Puuperäiset polymeerit synteettisten sideaineiden korvaajina

Tämän kandidaatintyön aiheena oli löytää biojalostamon näkökulmasta käyttökelpoisia tuotantoreittejä puuperäisistä materiaaleista bioperäisiin kemikaaleihin, joilla olisi mahdollista korvata synteettisiä sideaineita. Tällä hetkellä suurin osa sideaineista ja päällystemateriaaleista tuotetaan uusiutumattomista luonnonvaroista, kuten maakaasusta ja öljystä. Lopputuotteiden kierrätettävyyden ja vihreyden ohella yksi metsäteollisuuden tulevaisuuden trendejä on pyrkiä irti öljy- ja maakaasuriippuvuudesta. Muutoksella voidaan säästää sekä ympäristöä, että rahaa. Biopohjaisilla drop-in kemikaaleilla ja muilla biopohjaisilla vaihtoehdoilla tämä on mahdollista Tässä työssä tutkittiin ja havainnollistettiin mahdollisin tuotantoreitein useiden tällä hetkellä käytössä olevien sideaineiden korvaamista biopohjaisilla versioilla. Työ tehtiin kirjallisuustutkielmana, eikä siihen kuulunut laboratoriokokeita. Työn ensimmäisessä osassa painopiste on biojalostamossa ja dispersiopäällystyksessä. Toisessa osassa esitellään tällä hetkellä käytettyjä sideaineita ja niiden mahdollisia biopohjaisia korvaajia tuotantoreitteineen. Työn toissijainen tarkoitus oli selvittää lyhyesti mitä muita puuperäisiä komponentteja voidaan käyttää suoraan paperin ja kartongin päällystämiseen. Viimeiseksi on esitelty vielä lyhyesti kaupallisesti käytössä olevia biomuoveja ja päällysteitä.

Adaptive Dynamics of Resource Specialization

Ecological specialization in resource utilization has various facades ranging from nutritional resources via host use of parasites or phytophagous insects to local adaptation in different habitats. Therefore, the evolution of specialization affects the evolution of most other traits, which makes it one of the core issues in the theory of evolution. Hence, the evolution of specialization has gained enormous amounts of research interest, starting already from Darwin’s Origin of species in 1859. Vast majority of the theoretical studies has, however, focused on the mathematically most simple case with well-mixed populations and equilibrium dynamics. This thesis explores the possibilities to extend the evolutionary analysis of resource usage to spatially heterogeneous metapopulation models and to models with non-equilibrium dynamics. These extensions are enabled by the recent advances in the field of adaptive dynamics, which allows for a mechanistic derivation of the invasion-fitness function based on the ecological dynamics. In the evolutionary analyses, special focus is set to the case with two substitutable renewable resources. In this case, the most striking questions are, whether a generalist species is able to coexist with the two specialist species, and can such trimorphic coexistence be attained through natural selection starting from a monomorphic population. This is shown possible both due to spatial heterogeneity and due to non-equilibrium dynamics. In addition, it is shown that chaotic dynamics may sometimes inflict evolutionary suicide or cyclic evolutionary dynamics. Moreover, the relations between various ecological parameters and evolutionary dynamics are investigated. Especially, the relation between specialization and dispersal propensity turns out to be counter-intuitively non-monotonous. This observation served as inspiration to the analysis of joint evolution of dispersal and specialization, which may provide the most natural explanation to the observed coexistence of specialist and generalist species.

Functionalisation of spruce O-acetyl-galactoglucomannans for barrier and composite applications

The increasing use of energy, food, and materials by the growing population in the world is leading to the situation where alternative solutions from renewable carbon resources are sought after. The growing use of plastics depends on the raw-oil production while oil refining are politically governed and required for the polymer manufacturing is not sustainable in terms of carbon footprint. The amount of packaging is also increasing. Packaging is not only utilising cardboard and paper, but also plastics. The synthetic petroleum-derived plastics and inner-coatings in food packaging can be substituted with polymeric material from the renewable resources. The trees in Finnish forests constitute a huge resource, which ought to be utilised more effectively than it is today. One underutilised component of the forests is the wood-derived hemicelluloses, although Spruce Oacetyl-galactoglucomannans (GGMs) have previously shown high potential for material applications and can be recovered in large scale. Hemicelluloses are hydrophilic in their native state, which restrains the use of them for food packaging as non-dry item. To cope with this challenge, we intended to make GGMs more hydrophobic or amphiphilic by chemical grafting and consequently with the focus of using them for barrier applications. Methods of esterification with anhydrides and cationic etherification with a trimethyl ammonium moiety were established. A method of controlled synthesis to obtain the desired properties by the means of altering temperature, reaction time, the quantity of the reagent, and even the solvent for purification of the products was developed. Numerous analytical tools, such as NMR, FTIR, SEC-MALLS/RI, MALDI-TOF-MS, RP-HPLC and polyelectrolyte titration were used to evaluate the products from different perspectives and to acquire parallel proofs of their chemical structure. Modified GGMs with different degree of substitution and the correlating level of hydrophobicity was applied as coatings on cartonboard and on nanofibrillated cellulose-GGM films to exhibit barrier functionality. The water dispersibility in processing was maintained with GGM esters with low DS. The use of chemically functionalised GGM was evaluated for the use as barriers against water, oxygen and grease for the food packaging purposes. The results show undoubtedly that GGM derivatives exhibit high potential to function as a barrier material in food packaging.

Esiselvitys puupolttoaineen jalostamisesta torrefiointitekniikalla

Fossiilisten polttoaineiden käytöstä aiheutuvia kasvihuonekaasupäästöjä pyritään vähentämään EU:ssa mm. päästökaupan avulla. Uusiutumattomien polttoaineiden tilalle kehitetään biopolttoaineita, joita voidaan hyödyntää olemassa olevien voimalaitosten polttolaitteistoilla. Biopolttoaineiden etuna on, ettäniiden ei katsota lisäävän hiilidioksidipäästöjä, koska biomassa sitoo itseensä kasvaessaan poltossa vapautuvan määrän hiiltä. Eräs kiinnostavimmista jalostetuista biopolttoaineista on torrefioitu puu, joka vastaa useimmilta ominaisuuksiltaan kivihiiltä ja jota voidaan käyttää hiilivoimalaitoksissa ilman laitteistomuutoksia. Torrefiointi on puun eräänlaista paistamista hapettomissa olosuhteissa 250-270ºC:ssa, jolloin siitä saadaanpoistettua vesi ja osa haihtuvista aineista. Puun väri muuttuu suklaanruskeaksi, se kevenee, ei savuta poltettaessa, hylkii vettä, jauhautuu hyvin sekä sillä on pienet hiukkaspäästöt. Käsitellyn puun ominaisuudet muuttuvat säilyvyydeltään ja käyttöominaisuuksiltaan merkittävästi raaka-aineeseen verrattuna. Torrefioinnilla saavutetaan puulle polttoainekäytön kannalta myös paremmat ja kestävämmät ominaisuudet kuin hiiltämällä. Torrefiointiprosessia on tutkittu jonkin verran ja torrefioidun biomassan polttoa voimalaitosmittakaavassa on kokeiltu pienessä mittakaavassa. Torrefioitu materiaali on alhaisen tiheytensä vuoksi hankalaa ja kallista kuljettaa,joten sen tiheyttä tulee nostaa kuljetuksia varten tiivistämällä esim.pelletöimällä. Torrefionti yhdistettynä pelletöintiin on parhaimmillaan kilpailukykyinen vaihtoehto, kun kivihiiltä korvaavaa biomassaa jalostetaan kaukana käyttöpaikasta ja kuljetetaan irtotavarana aluskuljetuksina. Torrefioitua puuta on tiettävästi poltettu vain hollantilaisessa voimalaitoksessa. Tässä esiselvityksessä kootun tiedon perusteella torrefioidun puupolttoaineen tuottamiseen Suomen olosuhteissa arvioidaan olevan teknis-taloudellisia mahdollisuuksia. Kuitenkin torrefiointiprosessin soveltaminen suomen olosuhteisiin ja kotimaisiin raakaaineisiin vaatii panostusta jatkotutkimukseen ennen varsinaiseen toteutusvaiheeseen siirtymistä.

Design and production of protein nanostructures for biomolecular detection

Particulate nanostructures are increasingly used for analytical purposes. Such particles are often generated by chemical synthesis from non-renewable raw materials. Generation of uniform nanoscale particles is challenging and particle surfaces must be modified to make the particles biocompatible and water-soluble. Usually nanoparticles are functionalized with binding molecules (e.g., antibodies or their fragments) and a label substance (if needed). Overall, producing nanoparticles for use in bioaffinity assays is a multistep process requiring several manufacturing and purification steps. This study describes a biological method of generating functionalized protein-based nanoparticles with specific binding activity on the particle surface and label activity inside the particles. Traditional chemical bioconjugation of the particle and specific binding molecules is replaced with genetic fusion of the binding molecule gene and particle backbone gene. The entity of the particle shell and binding moieties are synthesized from generic raw materials by bacteria, and fermentation is combined with a simple purification method based on inclusion bodies. The label activity is introduced during the purification. The process results in particles that are ready-to-use as reagents in bioaffinity. Apoferritin was used as particle body and the system was demonstrated using three different binding moieties: a small protein, a peptide and a single chain Fv antibody fragment that represents a complex protein including disulfide bridge.If needed, Eu3+ was used as label substance. The results showed that production system resulted in pure protein preparations, and the particles were of homogeneous size when visualized with transmission electron microscopy. Passively introduced label was stably associated with the particles, and binding molecules genetically fused to the particle specifically bound target molecules. Functionality of the particles in bioaffinity assays were successfully demonstrated with two types of assays; as labels and in particle-enhanced agglutination assay. This biological production procedure features many advantages that make the process especially suited for applications that have frequent and recurring requirements for homogeneous functional particles. The production process of ready, functional and watersoluble particles follows principles of “green chemistry”, is upscalable, fast and cost-effective.

Etelä-Karjalan pienten ja keskisuurten konepaja- ja kunnossapitoyritysten energiaohjelma

Työssä tutkitaan Etelä-Karjalan alueella olevien uusiutuvien energiavarojen lisäämisen mahdollisuuksia sekä energian kulutuksen vähennysmahdollisuuksia energiatehokkuuden avulla pienissä ja keskisuurissa konepaja- ja kunnossapitoyrityksissä. Energiaohjelman pohjalla on EU:n halu jalkauttaa energia- ja ilmastotavoitteensa pieniin ja keskisuuriin yrityksiin. Ohjelma on muodostettu yritysryhmän mielipiteet ja tarpeet, sekä Etelä-Karjalan alueen ominaispiirteet huomioon ottaen. Energiaohjelmaa muodostettaessa perehdyttiin sekä EU:n että Suomen energiapolitiikkaan ja Etelä-Karjalan alueellisiin ominaisuuksiin ja energiantuotantotapoihin. Lisäksi yrityksiä haastateltiin energia-asioista ja niihin liittyvistä asenteista sekä perehdyttiin yritysten energiatehokkuuteen. Haastattelujen ja alueellisen energiarakenteen pohjalta päädyttiin muodostamaan energiaohjelma energiatehokkuuteen painottuen, koska alueen uusiutuvia luonnonvaroja on jo hyödynnetty melko tehokkaasti. Energiaohjelmaa testattiin pilottiprojektissa, joka toteutettiin työssä teoreettisena laskentana. Pilottiprojektin laskennasta saatiin lupaavia tuloksia. Laskennassa käytettävistä arvoista suurin osa saatiin pilottiprojektin yritykseltä tai muista lähteistä, mutta osa arvioitiin itse. Pilottiprojektista saatujen tietojen perusteella voidaan energiaohjelman väittää toimivan ainakin tarkastelussa mukana olleessa yritysryhmässä Etelä-Karjalan alueella. Energiaohjelma voi edistää yritysryhmän energiatehokkuutta vain jos se otetaan yrityksissä käyttöön. Ohjelmaa on mahdollista kehittää lisää muun muassa yksinkertaistamalla laskentaa. Jatkokehittelyllä on mahdollista luoda EU:n alueelle sopiva energiantehokkuustarkasteluun käytettävä ohjelma.

Metanolin tuotanto biomassasta

Tämä työ käsittelee eri tapoja, joilla biomassasta voidaan valmistaa metanolia. Työssä käydään läpi eri valmistusreitit sekä tarkastellaan biomassaa raaka-aineena. Työhön on myös koottu joidenkin maailmalla tehtyjen tutkimusten aine- ja energiataseita. Tutkimusten pohjalta mietitään onko metanolin tuotanto liikennepolttoaineeksi tällä hetkellä taloudellisesti tai energiatehokkuudeltaan järkevää. Metanolia voidaan valmistaa biomassasta pääsääntöisesti viidellä eri tavalla. Ensimmäinen tapa on kaasuttaa biomassaa, jolloin tuotetaan raaka-kaasua. Raaka-kaasusta jalostetaan synteesikaasua, josta voidaan metanolisynteesillä valmistaa metanolia. Toinen tapa metanolin valmistamiseksi on liittää tuotanto sellunkeiton yhteyteen. Tällöin raaka-aineena olisi selluprosessissa syntyvä mustalipeä, josta metanoli voidaan erottaa. Kolmas mahdollinen valmistusprosessi on biomassan mädätys. Mädätyksessä syntyy biokaasua, josta jalostetaan synteesikaasuaja siitä edelleen metanolia. Neljäs keino metanolin valmistamiseksi biomassasta on pyrolyysi. Puun pyrolyysissä puu kuumennetaan nopeasti hapettomissa tai rajallisen hapensaannin olosuhteissa. Prosessissa syntyvästä pyrolyysiöljystä voidaan erottaa metanolia tislaamalla. Viides mahdollinen reitti metanolin valmistukselle on Fischer¬–Tropsch-synteesi. Biomassasta saatu synteesikaasu johdetaan FT-synteesiin, jossa katalyyttisesti saadaan hiilivetyjen ohella tuotettua metanolia. Biopolttoaineiden kuten metanolin valmistusprosesseja tutkitaan ja kehitetään jatkuvasti, sillä uusiutumattomat energianlähteet eivät riitä loputtomasti ja niiden aiheuttamia hiilidioksidipäästöjä halutaan vähentää. Tällä hetkellä tuotantoteknologiat eivät ole vielä tarpeeksi kehittyneet, jotta tuotanto saataisiin vastaamaan kulutusta. Metanolia ei kuitenkaan vielä voida käyttää sellaisenaan liikennepolttoaineena, joten metanolin markkinat ainakin vielä ovat sillä saralla varsin kapeat.

Legitimacy Building in Public Disclosures on Strategic Energy Investments

Renewable energy investments play a key role in energy transition. While studies have suggested that social acceptance may form a barrier for renewable energy investments, the ways in which companies perceive and attempt to gain the acceptance have received little attention. This study aims to fill the gap by exploring how large electric utilities justify their strategic investments in their press releases and how do the justifications differ between renewable and non-renewable energy investments. The study bases on legitimacy theory and aims at contributing to the research on legitimation in institutional change. As its research method, the study employs an inductive mixed method content analysis. The study has two parts: a qualitative content analysis that explores and identifies the themes and legitimation strategies of the press releases and a quantitative computer-aided analysis that compares renewable and non-renewable energy investments. The sample of the study consists of 396 press releases representing the strategic energy investments of 34 electric utilities from the list of the world’s 250 largest and financially most successful energy companies. The data is collected from the period of 2010–2014. The study reveals that most important justifications for strategic energy investments are fit with the strategy and environmental and social benefits. Justifications address especially the expectations of market. Investments into non-renewable energy are justified more and they use more arguments addressing the proprieties and performance of power plants whereas renewable energy investments are legitimized by references to past actions and commonly accepted morals and norms. The findings support the notion that validity-addressing and propriety-addressing legitimation strategies are used differently in stable and unstable institutional settings.

Organizational creativity – Hegemonic and alternative discourses

SUMMARY Organizational creativity – hegemonic and alternative discourses Over the course of recent developments in the societal and business environment, the concept of creativity has been brought into new arenas. The rise of ‘creative industries’ and the idea of creativity as a form of capital have attracted the interests of business and management professionals – as well as academics. As the notion of creativity has been adopted in the organization studies literature, the concept of organizational creativity has been introduced to refer to creativity that takes place in an organizational context. This doctoral thesis focuses on organizational creativity, and its purpose is to explore and problematize the hegemonic organizational creativity discourse and to provide alternative viewpoints for theorizing about creativity in organizations. Taking a discourse theory approach, this thesis, first, provides an outline of the currently predominant, i.e. hegemonic, discourse on organizational creativity, which is explored regarding themes, perspectives, methods and paradigms. Second, this thesis consists of five studies that act as illustrations of certain alternative viewpoints. Through these exemplary studies, this thesis sheds light on the limitations and taken-for-granted aspects of the hegemonic discourse and discusses what these alternative viewpoints could offer for the understanding of and theorizing for organizational creativity. This study leans on an assumption that the development of organizational creativity knowledge and the related discourse is not inevitable or progressive but rather contingent. The organizational creativity discourse has developed in a certain direction, meaning that some themes, perspectives, and methods, as well as assumptions, values, and objectives, have gained a hegemonic position over others, and are therefore often taken for granted and considered valid and relevant. The hegemonization of certain aspects, however, contributes to the marginalization of others. The thesis concludes that the hegemonic discourse on organizational creativity is based on an extensive coverage of certain themes and perspectives, such as those focusing on individual cognitive processes, motivation, or organizational climate and their relation to creativity, to name a few. The limited focus on some themes and the confinement to certain prevalent perspectives, however, results in the marginalization of other themes and perspectives. The negative, often unintended, consequences, implications, and side effects of creativity, the factors that might hinder or prevent creativity, and a deeper inquiry into the ontology and epistemology of creativity have attracted relatively marginal interest. The material embeddedness of organizational creativity, in other words, the physical organizational environment as well as the human body and its non-cognitive resources, has largely been overlooked in the hegemonic discourse, although thereare studies in this area that give reason to believe that they might prove relevant for the understanding of creativity. The hegemonic discourse is based on an individual-centered understanding of creativity which overattributes creativity to an individual and his/her cognitive capabilities, while simultaneously neglecting how, for instance, the physical environment, artifacts, social dynamics and interactions condition organizational creativity. Due to historical reasons, quantitative as well as qualitative yet functionally- oriented studies have predominated the organizational creativity discourse, although studies falling into the interpretationist paradigm have gradually become more popular. The two radical paradigms, as well as methodological and analytical approaches typical of radical research, can be considered to hold a marginal position in the field of organizational creativity. The hegemonic organizational creativity discourse has provided extensive findings related to many aspects of organizational creativity, although the con- ceptualizations and understandings of organizational creativity in the hegemonic discourse are also in many respects limited and one-sided. The hegemonic discourse is based on an assumption that creativity is desirable, good, necessary, or even obligatory, and should be encouraged and nourished. The conceptualiza- tions of creativity favor the kind of creativity which is useful, valuable and can be harnessed for productivity. The current conceptualization is limited to the type of creativity that is acceptable and fits the managerial ideology, and washes out any risky, seemingly useless, or negative aspects of creativity. It also limits the possible meanings and representations that ‘creativity’ has in the respective discourse, excluding many meanings of creativity encountered in other discourses. The excessive focus on creativity that is good, positive, productive and fits the managerial agenda while ignoring other forms and aspects of creativity, however, contributes to the dilution of the notion. Practices aimed at encouraging the kind of creativity may actually entail a risk of fostering moderate alterations rather than more radical novelty, as well as management and organizational practices which limit creative endeavors, rather than increase their likelihood. The thesis concludes that although not often given the space and attention they deserve, there are alternative conceptualizations and understandings of organizational creativity which embrace a broader notion of creativity. The inability to accommodate the ‘other’ understandings and viewpoints within the organizational creativity discourse runs a risk of misrepresenting the complex and many-sided phenomenon of creativity in organizational context.

Value co-creation in bio-based chemicals value network

The purpose of this Master’s thesis is to study value co-creation in emerging value network. The main objective is to examine how value is co-created in bio-based chemicals value network. The study provides insights to different actors’ perceived value in the value network and enlightens their motivations to commit to the collaborative partnerships with other actors. Empirical study shows that value co-creation is creation of mutual value for both parties of the relationship by combining their non-competing resources to achieve a common goal. Value co-creation happens in interactions, and trust, commitment and information sharing are essential prerequisites for value co-creation. Value co-creation is not only common value creation, but it is also value that emerges for each actor because of the co-operation with the other actor. Even though the case companies define value mainly in economic terms, the other value elements like value of the partnership, knowledge transfer and innovation are more important for value co-creation.

Sustainability of protein production by bioreactor processes using wind and solar power as energy sources

Food production account for significant share of global environmental impacts. Impacts are global warming, fresh water use, land use and some non-renewable substance consumption like phosphorous fertilizers. Because of non-sustainable food production, the world is heading to different crises. Both food- and freshwater crises and also land area and phosphorous fertilizer shortages are one of many challenges to overcome in near future. The major protein sources production amounts, their impacts on environment and uses are show in this thesis. In this thesis, a more sustainable than conventional way of biomass production for food use is introduced. These alternative production methods are photobioreactor process and syngas-based bioreactor process. The processes’ energy consumption and major inputs are viewed. Their environmental impacts are estimated. These estimations are the compared to conventional protein production’s impacts. The outcome of the research is that, the alternative methods can be more sustainable solutions for food production than conventional production. However, more research is needed to verify the exact impacts. Photobioreactor is more sustainable process than syngas-based bioreactor process, but it is more location depended and uses more land area than syngas-based process. In addition, the technology behind syngas-based application is still developing and it can be more efficient in the future.

Renewable energy scenarios for South Karelia – non-industrial energy demands

Tässä diplomityössä tarkastellaan täysin uusiutuvaa energiajärjestelmää Etelä-Karjalan maakunnan alueella, mikä onkin jo tällä hetkellä Suomen uusiutuvin maakunta. Diplomityössä tarkastellaan julkisen sektorin, liikenteen ja rakennusten energian kulutusta mutta teollisuuden energiankäyttö jätetään tarkastelun ulkopuolelle. Työssä tutustutaan tämän hetken Etelä-Karjalan energiajärjestelmään ja sen perusteella tehdään referenssi-skenaario. Tulevaisuuden skenaariot tehdään vuosille 2030 ja 2050. Tulevaisuuden skenaarioissa muutos keskittyy järjestelmän sähköistymiseen ja uusiutuvien tuotantomuotojen integroimiseen järjestelmään. Sähköistyminen kasvattaa sähkönkulutusta, joka pyritään kattamaan uusiutuvilla tuotantomuodoilla, lähinnä tuuli- ja aurinkovoimalla. Liikennesektori rajataan kumipyöräliikenteeseen ja sen muutos tulee olemaan haastavin ja aikaa vievin. Muutokseen pyritään liikennepolttoaineiden tuotannolla maakunnassa sekä sähköautoilulla. Uusiutuva energiajärjestelmä tarvitsee tuotannon ja kysynnän joustoa sekä älyä järjestelmältä. Työssä tarkastellaan myös järjestelmän kustannuksia sekä työllisyysvaikutuksia.

Distributed Energy Production in the North-West Region of Russia

The energy system of Russia is the world's fourth largest measured by installed power. The largest are that of the the United States of America, China and Japan. After 1990, the electricity consumption decreased as a result of the Russian industry crisis. The vivid economic growth during the latest few years explains the new increase in the demand for energy resources within the State. In 2005 the consumption of electricity achieved the maximum level of 1990 and continues to growth. In the 1980's, the renewal of power facilities was already very slow and practically stopped in the 1990's. At present, the energy system can be very much characterized as outdated, inefficient and uneconomic because of the old equipment, non-effective structure and large losses in the transmission lines. The aim of Russia's energy reform, which was started in 2001, is to achieve a market based energy policy by 2011. This would thus remove the significantly state-controlled monopoly in Russia's energy policy. The reform will stimulateto decrease losses, improve the energy system and employ energy-saving technologies. The Russian energy system today is still based on the use of fossil fuels, and it almost totally ignores the efficient use of renewable sources such as wind, solar, small hydro and biomass, despite of their significant resources in Russia. The main target of this project is to consider opportunities to apply renewable energy production in the North-West Federal Region of Russia to partly solve the above mentioned problems in the energy system.

Competence Development and Capacity Building of Sawmill Enterprises in Kenya – A Human Resources Development Approach

The Kenyan forestry and sawmilling industry have been subject to a changing environment since 1999 when the industrial forest plantations were closed down. This has lowered raw material supply and it has affected and reduced the sawmill operations and the viability of the sawmill enterprises. The capacity of the 276 registered sawmills is not sufficient to fulfill sawn timber demand in Kenya. This is because of the technological degradation and lack of a qualified labor force, which were caused because of non-existent sawmilling education and further training in Kenya. Lack of competent sawmill workers has led to low raw material recovery, under utilization of resources and loss of employment. The objective of the work was to suggest models, methods and approaches for the competence and capacity development of the Kenyan sawmilling industry, sawmills and their workers. A nationwide field survey, interviews, questionnaire and literature review was used for data collection to find out the sawmills’ competence development areas and to suggest models and methods for their capacity building. The sampling frame included 22 sawmills that represented 72,5% of all the registered sawmills in Kenya. The results confirmed that the sawmills’ technological level was backwards, productivity low, raw material recovery unacceptable and workers’ professional education low. The future challenges will be how to establish the sawmills’ capacity building and workers’ competence development. Sawmilling industry development requires various actions through new development models and approaches. Activities should be started for technological development and workers’ competence development. This requires re-starting of vocational training in sawmilling and the establishment of more effective co-operation between the sawmills and their stakeholder groups. In competence development the Enterprise Competence Management Model of Nurminen (2007) can be used, whereas the best training model and approach would be a practically oriented learning at work model in which the short courses, technical assistance and extension services would be the key functions.
