Abstract: The urgent and relevant goals of providing a healthier diet and sustainable food systems taken together require a systematic approach that considers a broader environment for food choice. The paper compares three technologies to produce functional ingredients for preventing oncological diseases - each of them involving different sources of raw materials - a by-product of soybean processing, wild meadowsweet extract and planted meadowsweet extract. Life cycle assessment (LCA) has been selected to justify the choice of raw ingredients and the best technology for the stakeholders. Life cycle inventory analysis (LCIA) of technologies was carried out based on the SimaPro 9.1.1.1. To confirm the results of the LCIA of technologies to produce biologically active substances (BAS) from by-products of soybean oil processing, the following models of the SimaPro 9.1.1.1 software were used: EPD (2018) V1.01, ReCiPe 2016 (Midpoint (H) V1.04 / World (2010) H) and IPCC 2013 (GWP 500a V1.01). The validation of the results and the assessment of the impact of uncertainties in the initial data on the LCA calculations of the technologies were carried out using Monte Carlo method. The results showed that production of BAS from a by-product of soybean oil processing is the most environmentally friendly technology, and the data obtained could add to the life cycle database for the category of “Functional food ingredients” or serve as an example for further research and comparison with other targeted functional ingredients.

Abstract: Currently, in Russia there is no established system of sugar waste treatment, while their forming is increasing every year However the waste of sugar production is a valuable raw material that can serve as a source of energy and commodity goods, and their placement in landfills increases the irreversible climate change The relevance of agricultural waste treatment is confirmed by the existing legal acts, such as the Doctrine of Food Security and Climate Doctrine of the Russian Federation, as well as the State programs of agricultural development The given study focuses on comparison of environmental impacts and economic costs and benefits of four scenarios of processing of sugar production waste such as placing at the landfill, incineration, accelerated anaerobic digestion and the production of secondary product, a valuable food ingredient – pectin The research method for examination of the scenarios is simulation modeling

Abstract: The potential health and environmental impacts associated with the improper management of chemically treated wood waste demands the adoption of recycling, and disposal practices. Chemically treated wood waste has several physical and chemical properties which makes it usable for the manufacture of another product to multiple use, among which the production of paper and fuel. This paper presents the initial life cycle assessment (LCA) study on wood waste used for paper production. The study boundary is limited with raw materials (raw wood or waste wood) processing and paper production itself, thus corresponds to “gate-to-gate” life cycle with a special focus on life cycle inventory data on waste wood treatment via hydrolysis process. The results of the analysis demonstrate competitiveness of the waste wood use for paper production vs. raw wood in such environmental categories as human health and ecosystem quality.

Abstract: The second Lahti Cleantech Annual Review consists of eleven articles written by Lahti University of Applied Science’s experts from the Faculty of Technology and Institute of Design, and Lahti UAS partners from the City of Lahti and Lahti Region Development LADEC Ltd. The aim of the review is to present the latest interesting research and development projects in the field of cleantech. The focus of the review is on work related to material efficiency, energy efficiency and sustainable urban environment, which are the main themes of cleantech activities at Lahti UAS.Lahti Cleantech Annual Review supports communication with Lahti UAS’s partner universities, companies and other stakeholders, and it is also a part of implementation of cleantech themes in the Lahti UAS RD and educational operations. This Lahti Cleantech Annual Review is published as a part of REISKA: New Business Using Resource Efficiency project funded by the European Regional Development Fund.

Abstract: Meadowsweet (Filipendula ulmaria) is an essential oil-bearing, pharmacologically valuable medicinal plant growing wild in floodlands that are either not usually used for agriculture or have low economic value. The aim of this work was to understand the relationship between the yield of F. ulmaria inflorescences and the qualitative and quantitative composition of the essential oil during flowering stages in different habitats. Five different habitats of F. ulmaria were investigated for evaluation of inflorescence characteristics (length and weight) and the quantitative and qualitative composition of essential oils in early and late blooming stages (growing stage BBCH 62–63 and BBCH 65–67/72–73, respectively). The results showed significant (p < 0.05) positive correlations between the length and weight of inflorescences both in early and in late blooming stages (r = 0.73 and r = 0.72, respectively). The early blooming stage was observed to have 1.2–2 times greater quantity of volatile oils in comparison with the late blooming stage. Salicylaldehyde and methylsalicylate were the main salicylates in both blooming stages. Spearman’s correlation showed statistically significant relationship between percentages of salicylaldehyde and methylsalicylate (r = −0.94, p < 0.05). An increase in salicylaldehyde was accompanied by a decrease in methylsalicylate in essential oils. Statistically significant relations between the investigated parameters of plant and the parameters of habitat were not detected. The dried raw material yield of F. ulmaria in 1 ha in the late blooming stage was 18–56% higher than in the early blooming stage; however, the yield of essential oil in the early flowering stage was 1.5–1.6 times higher than in the late flowering stage. The obtained research data suggest that the low economic value of floodlands—the habitats of F. ulmaria—can be increased by using these areas as natural industrial plots.

Abstract: Most companies aimed at long-term sustainable development take full responsibility to reduce the environmental risks in order to guarantee environmental safety and social justice of the planet’s population. In accordance with circular economy principles, energy efficiency and energy saving are currently among the most important strategic directions for technological development of many enterprises. For transition to «low carbon» development scenario, companies are setting priorities and goals, taking into account the concept of sustainable development, considering the energy consumption index or energy usage ratio as one of the key business indicators. An analysis of existing methods and approaches in companies’ energy management show a low level of strategic planning and management. To improve energy efficiency and implementation of energy policy, as well as to create conditions for company’s sustainable development in long term, it is necessary to apply innovative management methods. Such approaches as transition engineering and participatory backcasting will allow companies to determine the main directions of strategic business development in the field of energy efficiency. The need to improve methodological approaches to managing the energy sector of the enterprise’s economy determines the relevance of the chosen research topic. The aim of this paper is to present the results of CREA-RE-RU project, which deals with circular economy and resource efficiency development. The project investigated following key points: existing methods and approaches for managing energy resources of an enterprise; a review of innovation management methods for improving the energy efficiency of companies; application of the «transition engineering» approach to the formation of the company's energy development strategy; the results of application of the «transition engineering» approach for developing an energy efficiency strategy for the brewery company.
