Opis: Agriculture and food production can cause a variety of adverse environmental impacts. Life Cycle Assessment (LCA) is the only standardised method so far that provides a comprehensive assessment of the environmental burden of products. LCA results can be expressed as environmental impacts (midpoint level) or environmental damage (endpoint level). Communication on environmental impact is mostly carried out as a part of the Carbon Footprint (CF) or Environmental Product Declaration (EPD), while reporting on environmental damage is rarely used. Due to the growing interest of consumers in ‘healthy’ food, it is important that food producers address the environmental damage. Therefore, an overview of existing Life Cycle Impact Assessment (LCIA) methods that provide insight into endpoint indicators describing damage to human health has been performed and presented in this paper. The application of the selected LCIA methods is demonstrated for the case of food products, highlighting the fact that the results obtained by different LCIA methods are not directly comparable due to a variety of methodological limitations, such as the existence of different environmental indicators and their structure. Finally, the usage of the LCA method for designing food products is presented, with the aim of enabling consumers to choose diets with lower environment and human health impacts.

Opis: Every year approximately 70 million passenger cars are being produced and automotive industry is much bigger then just passenger cars. The impact of automotive industry on the environment is tre-mendous. From extracting raw materials through manufacturing and assembly processes, exploitation of the vehicle to the reprocessing irreversible, extensive environmental damage is done. The goal of this study is to show how implementing eco-design processes into supply chain management can re-duce the impact of automotive industry on the environment by e.g. reducing the use of the fuel, in-creasing the use of recycled materials. Focus is on evaluation of current state, environmental impacts and potential improvements for design, raw materials, manufacturing and distribution and end-of-life phase.

Opis: Giant goldenrod (S. gigantea Aiton) is considered an invasive weed in Europe, Asia, Australia, and New Zealand. In this research, the untreated and chitosan-treated cotton fabrics were functionalized with goldenrod inflorescences aqueous extract, at room temperature and 95°C. Zeta potential of fabrics was determined as a function of pH and the results showed an increased isoelectric point from 2.50 to 5.25 and amphoteric character of the chitosan-treated sample. The antioxidant activity (AA) of extract and functionalized fabrics was determined using DPPH analysis, while color and ultraviolet protection factor (UPF) were determined spectroscopically before and after wash and lightfastness testing. The chitosan pretreatment and dyeing of cotton at higher temperature increased AA (from 41.19 ± 0.28 to 56.08 ± 0.25), UPF (from 33.05 to 51.59) and color strength (K/S) (from 1.74 to 2.21), providing dyed cotton with excellent UV protection and a free radical inhibition activity. The samples had good wash fastness in terms of color (ΔEab* < 1), but not in terms of UV protection (UPF value decreased after washing to 23.47). The overall lightfastness was good to excellent (the UPF values of chitosan and dyed samples did not change much after lightfastness test (UPF = 51.75).

Opis: According to Kotler (1998) the product is the first and most important element of the marketing combination. Product strategy should include consistent decisions "about the product combination, group of products, brands, packaging and labelling." (Kotler 1998: 459). After we identify green products we will especially be interested in specific strategies for developing green products and packaging and green brand positioning. Shortly green products can be labelled as more durable, non-toxic, made from recycled materials and have less or only necessary volume of packaging (Ottman 1997: 89). Broader definition is given by Peattie (1995) who also considers the social dimension under the concept of green. He considers the product or service as green, where its effect on the natural environment and its social impact in terms of production, use or disposal, is significantly improved with respect to conventional products and services (Peattie 1995). Green product strategy should be implemented through: - Development of green product, - Green brand, - Eco-label and - Eco-design.

Opis: Background and Purpose: Providing a win-win situation for enterprises and the environment is raising the importance of eco-innovation. This article sheds light on the eco-innovation activities implemented within the clusters of the South Eastern European region (hereafter the SEE region). The main objective of this paper is to provide an outline of the situation pertaining to the implementation of eco-innovation activities in analyzed clusters. Methodology: Empirical evidence is provided through the performance of survey research with a sample of 52 clusters, encompassing 11 countries of the SEE region. The basic research method used in this research was a questionnaire developed for cluster organizations, with which we gathered the data and afterwards conducted descriptive statistics. Results: The findings demonstrate that the majority of analyzed clusters implement eco-innovation activities. The results indicate that 40 clusters out of 52 in all have set objectives with regard to eco-innovation support in their national or regional programs, followed by 35 clusters, which include objectives related to eco-innovation in their cluster strategies, and lastly, only 15 clusters are primarily focused on eco-innovation. Hence, our study depicting the current situation regarding the implementation of eco-innovation activities in analyzed clusters and clusters' orientation towards eco-innovation leads to us the discussion of why such differences in clusters occur. Conclusion: The huge differences related to the implementation of eco-innovation activities in clusters of the SEE region, can also reflect the level of the national/regional development in terms of economic indicators such as GDP and, at the same time, offer room for a lot of improvement, and an exchange of best practice.
