Dimensionality of quality from a customer perspective in the wood industry

The research analyzes product quality from a customer perspective in the case of the wood products industry. Of specific interest is to understand better how environmental quality is perceived from a customer perspective. The empirical material used comprises four data-sets from Finland, Germany and the UK, collected during 1992 2004. The methods consist of a set of quantitative statistical analyses. The results indicate that perceived quality from a customer perspective can be presented using a multidimensional and hierarchical construct with tangible and intangible dimensions, that is common to different markets and products. This applies in the case of wood products but also more generally at least for some other construction materials. For wood products, tangible product quality has two main sub-dimensions: technical quality and appearance. For product intangibles, a few main quality dimensions seem be detectable: Quality of intangibles related to the physical product, such as environmental issues and product-related information, supplier-related characteristics, and service and sales personnel behavior. Environmental quality and information are often perceived as being inter-related. Technical performance and appearance are the most important considerations for customers in the case of wood products. Organizational customers in particular also clearly consider certain intangible quality dimensions to be important, such as service and supplier reliability. The high technical quality may be considered as a license to operate , but product appearance and intangible quality provide potential for differentiation for attracting certain market segments. Intangible quality issues are those where Nordic suppliers underperform in comparison to their Central-European competitors on the important German markets. Environmental quality may not have been used to its full extent to attract customers. One possibility is to increase the availability of the environment-related information, or to develop environment-related product characteristics to also provide some individual benefits. Information technology provides clear potential to facilitate information-based quality improvements, which was clearly recognized by Finnish forest industry already in the early 1990s. The results indeed indicate that wood products markets are segmented with regard to quality demands

Biomassan energia-arvon nostaminen sekundäärilämmöllä kuivaamalla

Viime aikoina ilmastonmuutos, fossiilisten polttoaineiden väheneminen ja niiden hinnan nousu ovat lisänneet merkittävästi maailmanlaajuista kiinnostusta uusiutuviin energiavaroihin. Suomessa uusiutuvien energialähteiden käytössä on jo pitkään panostettu metsäteollisuuden sivutuotevirtana tuottamaan puuperäiseen biomassaan, jota metsäteollisuus käyttää energiantuotantoonsa. Metsäteollisuuden jätevesien käsittelyssä syntyy erilaisia lietteitä, jotka joko uusiokäytetään tai hävitetään polttamalla tai sijoittamalla kaatopaikalle. Erityisesti biolietteiden uusiokäyttö on hankalaa ja kaatopaikkasijoitus tulevaisuudessa mahdotonta tai ainakin kustannuksiltaan kohtuutonta. Käytännössä liete hävitetään polttamalla ja kuivaamalla siitä tulee polttoaine. Lietteiden energiakäyttö on järkevin tapa hävittää jäteliete. Lietteiden korkean vesipitoisuuden vuoksi ne tulee kuitenkin kuivata ennen polttoa. Lietteen kuivaaminen sekundäärienergiavirralla eli metsäteollisuusprosesseissa sivutuotteena muodostuvalla ns. hukkalämmöllä lisää lietteen poltosta saatavaa energiamäärää ja korvaa fossiilisten polttoaineiden käyttöä. Tutkimuksen tavoitteena oli selvittää lietteen kuivaukseen optimaalisin kuoren ja lietteen seossuhde eri kuivausparametrejä vaihdellen. Kokeellinen työ aloitettiin rakentamalla energiatekniikan koehalliin laboratoriokokoluokan kiintopetikuivuri, jossa kuivumista tutkittiin puhaltamalla polttoainepedin läpi lämmitettyä ilmaa. Kuivattavina polttoaineina olivat kuoren ja lietteen seos tai pelkkä kuori ja liete erilaisilla massoilla ja erilaisilla prosenttisilla suhteilla ja erilaisissa lämpötiloissa. Kuivumiskäyrien määritys perustui massanmuutokseen. Koelaitteessa olivat anturit lämpötilan mittausta varten, jotta lämpötila saatiin säädettyä ja seurattua kokeen edellyttämällä tavalla. Lämpötilat ja painonmuutokset tallentuivat koetta tehdessä tietokoneelle. Kuivauskokeet osoittivat, että liete-kuori seos kuivuu hyvin kiintopedissä kun lietteen massaosuus seoksessa on korkeintaan 50 %. Lietteen massaosuuden ollessa tätä suurempi kuivaaminen ei enää ole tehokasta, mikä johtuu luultavasti ilman suuresta kanavoitumisesta kuivauspedissä. Kuorta kuivatessa lämpötilan nosto 50 °C:stä 70 °C:een oli huomattavasti tehokkaampaa kuin 70 °C:stä 90 °C:een, ajallisesti ero oli noin kaksinkertainen.

CSR in forest industry – Case study of reporting and implementation of social responsibility in three international companies

Corporate Social Responsibility (CSR) has become increasingly important topic in forest industries, and other global companies, in recent years. Globalisation, faster information delivery and demand for sustainable development have set new challenges for global companies in their business operations. Also the importance of stakeholder relations, and pressure to become more transparent has increased in the forest industries. Three dimensions of corporate responsibility economic, environmental and social, are often included in the concept of CSR. Global companies mostly claim that these dimensions are equally important. This study analyses CSR in forest industry and has focus on reporting and implementation of social responsibility in three international companies. These case-companies are Stora Enso, SCA and Sappi, and they have different geographical base, product portfolios and therefore present interesting differences about forest industry strategy and CSR. Global Reporting Initiative (GRI) has created the most known and used reporting framework in CSR reporting. GRI Guidelines have made CSR reporting a uniform function, which can also be measured between companies and different sectors. GRI Guidelines have also made it possible to record and control CSR data in the companies. In recent years the use of GRI Guidelines has increased substantially. Typically CSR reporting on economic and environmental responsibility have been systematic in the global companies and often driven by legistlation and other regulations. However the social responsibility has been less regulated and more difficult to compare. Therefore it has previously been often less focused in the CSR reporting of the global companies. The implementation and use of GRI Guidelines have also increased dialogue on social responsibility issues and stakeholder management in global companies. This study analyses the use of GRI´s framework in the forest industry companies´ CSR reporting. This is a qualitative study and the disclosure of data is empricially analysed using content analysis. Content analysis has been selected as a method for this study because it makes it possible to use different sources of information. The data of this study consists of existing academic literature of CSR, sustainability reports of thecase-companies during 2005-2009, and the semi-structured interviews with company representatives. Different sources provide the possibility to look at specific subject from more than one viewpoint. The results of the study show that all case-companies have relatively common themes in their CSR disclosure, and the differences rise mainly from their product-portfolios, and geographic base. Social impacts to local communities, in the CSR of the companies, were mainly dominated by issues concerning creating wealth to the society and impacting communities through creation of work. The comparability of the CSR reporting, and especially social indicators increased significally from 2007 onwards in all case-companies. Even though the companies claim that three dimensions of CSR economic, environmental and social are equally important economic issues and profit improvement still seem to drive most of the operations in the global companies. Many issues that are covered by laws and regulations are still essentially presented as social responsibility in CSR. However often the unwelcome issues in companies like closing operations are covered just briefly, and without adequate explanation. To make social responsibility equally important in the CSR it would demand more emphasis from all the case-companies. A lot of emphasis should be put especially on the detail and extensiveness of the social reponsibility content in the CSR.

Afrikkalaisen sikaruton mahdollisia maahantuloreittejä

Afrikkalainen sikarutto on lakisääteisesti vastustettava helposti leviävä sikojen ja villisikojen virustauti, jolla on myös vakavia sosioekonomisia vaikutuksia. Akuutissa tautimuodossa eläimillä esiintyy syömättömyyttä, korkeaa kuumetta, verenpurkaumia iholla, veristä ulostetta sekä mahdollisesti ripulia. Kuolleisuus on lähes 100 % ja tauti johtaa kuolemaan 7-10 vrk tartunnan jälkeen. Tauti ei tartu ihmisiin. Tautia esiintyy sekä kesy- että villisioissa suurimmassa osassa Saharan eteläpuolista Afrikkaa ja Sardiniassa. Vuodesta 2007 lähtien tautia on esiintynyt Kaukasuksen alueella ja vuonna 2011 lähellä Suomen rajaa: Leningradin alueella ja Kuolan niemimaalla. Tässä riskiprofiilissa kartoitetaan reitit ja tapahtumasarjat, jotka voivat johtaa siihen, että afrikkalainen sikarutto tulee Suomeen ensimmäisen kerran. Näistä oleellisimmat ovat: maahantulo infektioalueella matkustaneiden ihmisten mukana, infektoituneen lihan tai lihatuotteen mukana, elävien kesysikojen ja sperman mukana, kontaminoituneiden eläinkuljetusajoneuvojen mukana, kansainvälisen liikenteen ruokajätteen mukana ja Suomeen vaeltavan infektoituneen villisian mukana. Tilatason tautisuojaus sekä tehokas ja kohdennettu tiedottaminen taudin vaaroista ovat avainasemassa, kun halutaan suojata Suomen sikaelinkeinoa afrikkalaiselta sikarutolta.

Learning Challenges in Biogas Production for Sustainability : An activity theoretical study of a network from a swine industry chain

This study is about the challenges of learning in the creation and implementation of new sustainable technologies. The system of biogas production in the Programme of Sustainable Swine Production (3S Programme) conducted by the Sadia food processing company in Santa Catarina State, Brazil, is used as a case example for exploring the challenges, possibilities and obstacles of learning in the use of biogas production as a way to increase the environmental sustainability of swine production. The aim is to contribute to the discussion about the possibilities of developing systems of biogas production for sustainability (BPfS). In the study I develop hypotheses concerning the central challenges and possibilities for developing systems of BPfS in three phases. First, I construct a model of the network of activities involved in the BP for sustainability in the case study. Next, I construct a) an idealised model of the historically evolved concepts of BPfS through an analysis of the development of forms of BP and b) a hypothesis of the current central contradictions within and between the activity systems involved in BP for sustainability in the case study. This hypothesis is further developed through two actual empirical analyses: an analysis of the actors senses in taking part in the system, and an analysis of the disturbance processes in the implementation and operation of the BP system in the 3S Programme. The historical analysis shows that BP for sustainability in the 3S Programme emerged as a feasible solution for the contradiction between environmental protection and concentration, intensification and specialisation in swine production. This contradiction created a threat to the supply of swine to the food processing company. In the food production activity, the contradiction was expressed as a contradiction between the desire of the company to become a sustainable company and the situation in the outsourced farms. For the swine producers the contradiction was expressed between the contradictory rules in which the market exerted pressure which pushed for continual increases in scale, specialisation and concentration to keep the production economically viable, while the environmental rules imposed a limit to this expansion. Although the observed disturbances in the biogas system seemed to be merely technical and localised within the farms, the analysis proposed that these disturbances were formed in and between the activity systems involved in the network of BPfS during the implementation. The disturbances observed could be explained by four contradictions: a) contradictions between the new, more expanded activity of sustainable swine production and the old activity, b) a contradiction between the concept of BP for carbon credits and BP for local use in the BPfS that was implemented, c) contradictions between the new UNFCCC1 methodology for applying for carbon credits and the small size of the farms, and d) between the technologies of biogas use and burning available in the market and the small size of the farms. The main finding of this study relates to the zone of proximal development (ZPD) of the BPfS in Sadia food production chain. The model is first developed as a general model of concepts of BPfS and further developed here to the specific case of the BPfS in the 3S Programme. The model is composed of two developmental dimensions: societal and functional integration. The dimension of societal integration refers to the level of integration with other activities outside the farm. At one extreme, biogas production is self-sufficient and highly independent and the products of BP are consumed within the farm, while at the other extreme BP is highly integrated in markets and networks of collaboration, and BP products are exchanged within the markets. The dimension of functional integration refers to the level of integration between products and production processes so that economies of scope can be achieved by combining several functions using the same utility. At one extreme, BP is specialised in only one product, which allows achieving economies of scale, while at the other extreme there is an integrated production in which several biogas products are produced in order to maximise the outcomes from the BP system. The analysis suggests that BP is moving towards a societal integration, towards the market and towards a functional integration in which several biogas products are combined. The model is a hypothesis to be further tested through interventions by collectively constructing the new proposed concept of BPfS. Another important contribution of this study refers to the concept of the learning challenge. Three central learning challenges for developing a sustainable system of BP in the 3S Programme were identified: 1) the development of cheaper and more practical technologies of burning and measuring the gas, as well as the reduction of costs of the process of certification, 2) the development of new ways of using biogas within farms, and 3) the creation of new local markets and networks for selling BP products. One general learning challenge is to find more varied and synergic ways of using BP products than solely for the production of carbon credits. Both the model of the ZPD of BPfS and the identified learning challenges could be used as learning tools to facilitate the development of biogas production systems. The proposed model of the ZPD could be used to analyse different types of agricultural activities that face a similar contradiction. The findings could be used in interventions to help actors to find their own expansive actions and developmental projects for change. Rather than proposing a standardised best concept of BPfS, the idea of these learning tools is to facilitate the analysis of local situations and to help actors to make their activities more sustainable.

Kymmenen teollisesti merkittävän puulajin kuoriuutteiden mahdollisuudet tuholaistorjunnassa

Metsäteollisuudesta kertyy vuosittain suuria määriä ylijäämämateriaalia, kuten puun kuorta ja oksia.Ylimääräinen aines käytetään pääasiassa energiantuotantoon, mutta uusia soveltamismahdollisuuksia kaivataan. Kuoren on havaittu olevan potentiaalinen lähde monille bioaktiivisille yhdisteille, joille olisi käyttöä esimerkiksi lääke- ja kemianteollisuudessa sekä maa-, metsä- ja puutarhatuotannon tuholaistorjunnassa. Tutkimus on osa Euroopan Unionin rahoittamaa ForestSpeCs-projektia, jonka tarkoituksena on selvittää metsäteollisuuden ylijäämämateriaalien vaihtoehtoisia käyttötapoja. Valittujen kymmenen teollisesti merkittävän pohjoisen puulajin (Abies nephrolepis, Betula pendula, Larix decidua, L. gmelinii, L. sibirica, Picea abies, P. ajanensis, P. pumila, Pinus sylvestris, Populus tremula) kuoresta uutettujen aineiden soveltuvuutta syönninestoaineeksi testattiin kaaliperhosen (Pieris brassicae L.) ja krysanteemiyökkösen (Spodoptera littoralis Boisduval) toukilla sekä osittain sinappikuoriaisella (Phaedon cochloreae Fabricius) ja idänlehtikuoriaisella (Agelastica alni L.). Uutteet valmistettiin yhteistyössä projektin ryhmien avulla tai itsenäisesti erilaisin menetelmin. Testaukset tehtiin laboratorio-oloissa käyttäen lehtikiekkojen valintabiotestiä sekä karkeilla uutteilla että niistä erotelluilla yksittäisillä yhdisteillä. Tehdyistä mittauksista laskettiin syönninestoindeksit (FDI). Tulosten perusteella lähes kaikki testatut uutteet vaikuttivat ainakin jossain määrin kohdehyönteisen syöntikäyttäytymiseen. Hieman yli puolet kaaliperhosella testatuista 46 uutteesta aiheuttivat yli 50 % syönnineston eli kaaliperhonen suosi kontrollilehtiä uutteella käsiteltyjä todennäköisemmin. Krysanteemiyökkösellä yli 50 %:n syönnineston aiheuttivat vain seitsemän testatuista 56 uutteesta. Lisäksi kolme uutetta lisäsi käsiteltyjen kiekkojen syöntiä merkittävästi. Idänlehtikuoriaistoukat ja -aikuiset karttoivat erityisesti abietiinihapolla käsiteltyjä lehtiä. Sinappikuoriaisella testatut uutteet toimivat myös lupaavasti. Testattujen puulajien kuoresta on mahdollista uuttaa biologisesti aktiivisia yhdisteitä, mutta tuholaistorjunnan kannalta oikeiden pitoisuuksien ja tehokkaiden uuttomenetelmien löytäminen vaatii jatkotutkimuksia. Kuoren sisältämien yhdisteiden laatu ja määrä vaihtelevat monien tekijöiden, kuten ympäristön ja genetiikan vaikutuksesta. Hyönteisten sietokyky vaihtelee myös paljon lajeittain ja yksilöidenkin välillä on eroja. Uutteista valmistettavia torjunta-aineita olisi kuitenkin mahdollista sisällyttää esimerkiksi integroituun torjuntaan muiden menetelmien rinnalle tulevaisuudessa.
