Consumers' biased perceptions of the environmental impact of products:influence on advertising efficiency

This paper investigates the main perceptual biases developed by consumers regarding the environmental impact of products. It shows that these biases make consumers unable to distinguish between advertisements for highly versus less sustainable products, but that the inclusion of relevant information can increase the efficiency of arguments for true sustainability.

Ethical consumption (in)decisons

Consumers’ indecisions about the ethical value of their choices are amongst the highest concerns regarding ethical products’ purchasing. This is especially true for Fair Trade certified products where the ethical attribute information provided by the packaging is often unacknowledged by consumers. While well-informed consumers are likely to generate positive consumer reactions to ethical products and increase its ethical consumption, less knowledgeable buyers show different purchasing patterns. In such circumstances, decisions are often driven by socio-cultural beliefs about the low functional performance of ethical or sustainable attributes. For instance, products more congruent with sustainability (e.g., produce) are considered to be simpler but less tasty than less sustainable products. Less sustainable products instead, are considered to be more sophisticated and to provide consumers with more hedonic pleasures (e.g., chocolate mousse). The extent that ethicality is linked with experiences that provide consumers with more pain than pleasure is also manifested in pro-social social behaviors. More specifically through conspicuous self-sacrificial consumption experiences like running for charity in marathons with wide public exposure. The willingness of consumers to engage in such costly initiatives is moderated by gender differences and further, mediated by the chronic productivity orientation of some individuals to use time in a productive manner. Using experimental design studies, I show that consumers (1) use a set of affective and cognitive associations with on-package elements to interpret ethical attributes, (2) implicitly associate ethicality with simplicity, and that (3) men versus women show different preferences in their forms of contribution to pro-social causes.

Fractionation of Hen Egg and Oat Lipids with supercritical Fluids Chemical and functional Properties of Fractions

Hen eggs and oats (Avena Sativa) are important materials for the food industry. Today, instead of merely satisfying the feeling of hunger, consumers are asking for healthier, biologically active and environmentally friendly products. The growing awareness of consumers’ increasing demands presents a great challenge to the food industry to develop more sustainable products and utilise modern and effective techniques. The modification of yolk fatty acid composition by means of feed supplements is well understood. Egg yolk phospholipids are polar lipids and are used in several applications including food, cosmetics, pharmaceuticals, and special nutrients. Egg yolk phospholipids are excellent emulsifiers, typically sold as mixtures of phospholipids, triacylglycerols, and cholesterol. However, highly purified and characterised phospholipids are needed in several sophisticated applications. Industrial fractionation of phospholipids is usually based on organic solvents. With these fractionation techniques, some harmful residues of organic solvents may cause problems in further processing. The objective of the present study was to investigate the methods to improve the functional properties of eggs, to develop techniques to isolate the fractions responsible for the specific functional properties of egg yolk lipids, and to apply the developed techniques to plant-based materials, too. Fractionation techniques based on supercritical fluids were utilised for the separation of the lipid fractions of eggs and oats. The chemical and functional characterisation of the fractions were performed, and the produced oat polar lipid fractions were tested as protective barrier in encapsulation processes. Modifying the fatty acid compositions of egg yolks with different types of oil supplements in feed had no affect on their functional or sensory properties. Based on the results of functional and sensory analysis, it is evident that eggs with modified fatty acid compositions are usable in several industrial applications. These applications include liquid egg yolk products used in mayonnaise and salad dressings. Egg yolk powders were utilised in different kinds of fractionation processes. The precipitation method developed in this study resembles the supercritical anti-solvent method, which is typically used in the pharmaceutical industry. With pilot scale supercritical fluid processes, non-polar lipids and polar lipids were successfully separated from commercially produced egg yolk powder and oat flakes. The egg and oat-based polar lipid fractions showed high purities, and the corresponding delipidated fractions produced using supercritical techniques offer interesting starting materials for the further production of bioactive compounds. The oat polar lipid fraction contained especially digalactosyadiacylglycerol, which was shown to have valuable functional properties in the encapsulation of probiotics.

Metsäteollisuuden ympäristöstrategia hallinnon näkökulmasta : Metsäteollisuuden kehitysskenaariot vuoteen 2020

Suomen metsäteollisuus elää voimakasta uusiutumis- ja murrosvaihetta, joka ilmenee muutoksina yksittäisten tehtaiden ja tehdasintegraattien toiminnassa. Monia yksikköjä on poistunut tuotannosta ja tuotannon painotusta on muutettu. Toisaalta metsäteollisuus on suuntaamassa uusille aloille, jolloin tuotteina voivat olla esimerkiksi erilaiset biopolttoaineet, kemianteollisuuden raaka-aineet ja uuden sukupolven paperi- ja kartonkituotteet. Metsäteollisuuden muuttuminen ja laitosten monimutkaistuminen sekä jatkuvasti lisääntyvä tiedontarve asettavat yhä suurempia vaatimuksia sekä toiminnanharjoittajien ympäristövastaaville että viranomaisille. Hallinnon jatkuva muutos ja niukkenevat voimavarat voivat johtaa siihen, että käytännön lupa- ja valvontatyöhön jää yhä vähemmän aikaa. Kaakkois-Suomen ELY-keskuksen koordinoima hanke ”Metsäteollisuuden ympäristöstrategia vuoteen 2020 – hallinnon näkökulma” pyrkii vastaamaan edellä mainittuihin haasteisiin strategiatyön avulla. Hankkeen tarkoituksena oli tarkastella metsäteollisuuden ympäristönäkökohtia niistä lähtökohdista, joihin yritys voi vaikuttaa raaka-aineen tulosta tehtaalle ja tuotteen lähdöstä tehtaalta sekä tehtaan perustamisesta sulkemiseen ja jälkihoitoon asti. Tavoitteena oli määritellä toiminnoille toimiva ympäristöstrategia. Strategiassa pyrittiin löytämään yhteisymmärrys toiminnanharjoittajan ja viranomaisen kanssa mm. siitä, miten otetaan käyttöön parhaat käytännöt niin teollisuudessa kuin hallinnossakin, toimitaan uusien BAT-, IED- ja vesienhoitoperiaatteiden mukaisesti sekä edistetään kestävän kehityksen mukaisten tuotteiden markkinoille tuloa ja otetaan ennakointi tavaksi -lähtökohta käyttöön kaikessa toiminnassa. Hanketyössä esille nousseet haasteet ryhmiteltiin aihealueittain kolmeksi pääkohdaksi tärkeysjärjestyksessä: viranomaisen ja teollisuuden tiedonkulun ja tietämyksen parantaminen, lupa-, valvonta- ja hallintoprosessien parantaminen sekä uusien haasteiden kartoittaminen ja niihin reagointi. Haasteiden ratkaisukeinoiksi etsittiin käytännön toimenpiteitä sekä määriteltiin niille vastuutahot. Toimenpiteiksi esitettiin mm. viranomaisen ja teollisuuden yhteisiä koulutuspäiviä, asiantuntijapaneelin perustamista sekä lupamääräysten antamista myös tehtaan tai tuotantoyksikön sulkemisen tai muuttamisen varalle. Riittävien resurssien ja tietotaidon turvaaminen niin hallinnossa kuin teollisuudessa on ehdoton edellytys toimenpiteiden onnistumiselle.

Green welding in practice

Efficient production and consumption of energy has become the top priority of national and international policies around the world. Manufacturing industries have to address the requirements of the government in relation to energy saving and ecologically sustainable products. These industries are also concerned with energy and material usage due to their rising costs. Therefore industries have to find solutions that can support environmental preservation yet maintain competitiveness in the market. Welding, a major manufacturing process, consumes a great deal of material and energy. It is a crucial process in improving a product’s life-cycle cost, strength, quality and reliability. Factors which lead to weld related inefficiencies have to be effectively managed, if industries are to meet their quality requirements and fulfil a high-volume production demand. Therefore it is important to consider some practical strategies in welding process for optimization of energy and material consumption. The main objective of this thesis is to explore the methods of minimizing the ecological footprint of the welding process and methods to effectively manage its material and energy usage in the welding process. The author has performed a critical review of the factors including improved weld power source efficiency, efficient weld techniques, newly developed weld materials, intelligent welding systems, weld safety measures and personnel training. The study lends strong support to the fact that the use of eco-friendly welding units and the quality weld joints obtained with minimum possible consumption of energy and materials should be the main directions of improvement in welding systems. The study concludes that, gradually implementing the practical strategies mentioned in this thesis would help the manufacturing industries to achieve on the following - reduced power consumption, enhanced power control and manipulation, increased deposition rate, reduced cycle time, reduced joint preparation time, reduced heat affected zones, reduced repair rates, improved joint properties, reduced post-weld operations, improved automation, improved sensing and control, avoiding hazardous conditions and reduced exposure of welder to potential hazards. These improvement can help in promotion of welding as a green manufacturing process.

Breves considerações sobre o conceito de natureza na genese da geografia moderna

From the twentieth century is witnessing a gradual increase in the debates and issues related to the degradation of nature, making the twenty-first century begins under the aegis of speeches linked to this concept as one of the axes of the concerns of humanity. There are several movements that are related to the degrading way of contemporary society and how we are called upon daily to save and defend nature, from the consumption of sustainable products through environmentally friendly lifestyles. While this may appear to be explicit that the current form of metabolic interaction man / nature in the current historical period of capitalism converges in a bleak scenario, however, there is an ideological and peacemaker convergence between productively and the systematic appeal to the consumption. Given these assumptions could be palpable the question that in the course of human history would be ideological conceptions of nature? Being a true statement what is the conflict present in the ideological struggle over nature with regard to the genesis of modern geography? Would it be overt or covert? These questions lead us to the present study, whose goal is to bring some notes about the ideological conceptions of the nature in human history, culminating in the possible influences upon the institutionalization of Modern Geography
