Abstract In this paper, a decision support approach for designing a family of environmentally benign products for a ranged set of customer requirements is presented. More specifically, we incorporate environmental issues in order to minimize the environmental impact of products without sacrificing their performance characteristics and keeping competitive prices in comparison to existing products. The example problem consists of the design of a family of environmentally benign oil filters based on a variety of oil flow rate ranges. Environmental issues are represented by Life Cycle Assessments and comparisons of the existing alternatives based on their environmental impact. Emphasis is placed on highlighting the trade-off analysis for including environmental considerations in the design of a family of products and not on the results of the problem, per se.

The Impact

The construction industry is responsible for 40–45% of primary energy consumption in Europe. Therefore, it is essential to find new materials with a lower environmental impact to achieve sustainable buildings. The objective of this study was to carry out the life cycle analysis (LCA) to evaluate the environmental impacts of baked clay bricks incorporating organic waste. The scope of this comparative study of LCA covers cradle to gate and involves the extraction of clay and organic waste from the brick, transport, crushing, modelling, drying and cooking. Local sustainability within a circular economy strategy is used as a laboratory test. The energy used during the cooking process of the bricks modified with organic waste, the gas emission concentrate and the emission factors are quantified experimentally in the laboratory. Potential environmental impacts are analysed and compared using the ReCiPe midpoint LCA method using SimaPro 8.0.5.13. These results achieved from this method are compared with those obtained with a second method—Impact 2002+ v2.12. The results of LCA show that the incorporation of organic waste in bricks is favourable from an environmental point of view and is a promising alternative approach in terms of environmental impacts, as it leads to a decrease of 15–20% in all the impact categories studied. Therefore, the suitability of the use of organic additives in clay bricks was confirmed, as this addition was shown to improve their efficiency and sustainability, thus reducing the environmental impact.

The results of life-cycle assessments (LCAs) of concrete are highly dependent on the concrete design method. In this study, LCAs were conducted to evaluate the environmental impacts of the replacement of sand with furnace bottom-ash (FBA) in concrete. In the FBA-based concretes, sand was replaced with FBA at proportions of 0, 30, 50, 70, and 100 wt%. Two design methods were studied: (i) concrete with fixed slump ranges of 0–10 mm (CON-fix-SLUMP-0-10) and 30–60 mm (CON-fix-SLUMP-30-60); and (ii) concrete with fixed water/cement (W/C) ratios of 0.45 (CON-fix-W/C-0.45) and 0.55 (CON-fix-W/C-0.55). The ReCiPe2016 midpoint and single-score (six methodological options) methods were used to compare the environmental damage caused by the FBA-based concretes. A two-stage nested (hierarchical) analysis of variance (ANOVA) was used to simultaneously evaluate the results of six ReCiPe2016 methodologies. The ReCiPe2016 results indicate that replacing sand with FBA decreased the environmental impact of the concretes with fixed slump ranges and increased the environmental impact of the concretes with fixed W/C ratios. Therefore, using FBA as a partial sand replacement in concrete production is of debatable utility, as its impact highly depends on the concrete design method used.

With the advancement of biotechnology, consumers are demanding more scientifically advanced products as well as being more concerned with the environmental impact of products. A life cycle carbon footprint assessment is an important tool in reaching net-zero carbon production goals. This paper presents the greenhouse gas emissions of functional foods by highlighting TCI Co., Ltd. as a case study. TCI conducted life cycle assessments (LCAs) on two mainstream products that utilize common manufacturing processes to examine their carbon footprint and gain a better understanding of their environmental impact. The main finding shows that while the manufacturing stage accounts for around 20–30% of emissions, the raw material stage accounts for 70–80% for both products. This suggests that TCI needs to work closely with its suppliers to ensure a low emissions supply chain and to achieve its net-zero target. Not only do these LCAs allow TCI to increase the products’ transparency, but they can also be offered as a reference to other businesses producing similar products. Sharing of knowledge and practices in the biotechnology industry benefits the entire ecosystem and improves corporate sustainability.

For educating a wide audience on the environmental impact of their daily life decisions, the Eco-Confessional has been developed as an interactive exhibit and a serious game. In this, the effectiveness of promoting sustainable lifestyles through life cycle thinking was explored. Based upon life cycle assessments, the eco-confessional reveals the environmental impact of eco-sins and good deeds performed in everyday life in a playful way. As the Eco-Confessional was being exhibited, it was evaluated to measure the impact of the new communication format. The goal of the project was to increase sustainable behavior by influencing both the desire and the ability to make sustainable decisions. The evaluation revealed that these goals were mostly achieved. By combining life cycle data with gamification elements, the Eco-Confessional succeeded in implementing a new scientainment approach to environmental education, which promotes life cycle thinking among the public.

Abstract This chapter discusses the environmental impact of insect rearing. Direct greenhouse gas (GHG) emissions from insects used as feed or food are discussed and data from life cycle assessments (LCAs) on commercially farmed insects are discussed per species. The relevance of the utilized feed on the environmental impact of insects and their derived products, including suggestions to lower this impact are also discussed. It is concluded that land use associated with insect production generally seems low, compared to conventional feed and food products. The EU (expressed as fossil fuel depletion) of insect production is often high compared to conventional products. To a large extent this is because several LCAs have been conducted for systems in temperate climates, which require extensive climate control.
