The bioeconomy can support Europe’s transition to a low-carbon economy and help to meet key international, European and member state sustainability targets through the provision of bio-based products and energy derived from sustainably sourced biomass. A successful implementation of a bio-based economy in Europe will, however, require a profound transformation of our production and consumption patterns. Consumer behavior will play a major role in supporting the successful transition to a bio-based economy. This paper uses a structured quantitative survey approach to gain an understanding of consumer perspectives in relation to bio-based products. Conducted among 18–75-year-old consumers in Ireland and the Netherlands, the study indicates that consumers in both countries have a relatively positive outlook regarding bio-based products, with Irish consumers showing a slightly more positive outlook. The study finds that a larger majority of Irish consumers would prefer buying bio-based products as opposed to fossil-based products, while Irish consumers also have a slightly more positive impression than Dutch consumers that their consumer choices can be beneficial for the environment.

Perennial rye grass is a widely used forage species in Ireland, on which the ruminant sector of agriculture is heavily dependent. While this species of grass is the primary source of fodder for cows, it is also abundant in plant protein, which could form a potential alternative ingredient in monogastric animal feed using a green biorefinery approach. In this study, perennial rye grass was processed using a novel biorefining process to extract value added products including protein as a potential replacement for soybean meal in monogastric feeds. Feed trials were conducted on a commercial farm with 55 weaner pigs for 31 days until slaughter. The diets comprised a control and a trial diet which integrated the green biorefinery protein concentrate. The effects of the new diet were determined by measuring the daily feed intake (DFI), average weight gain (AWG) and feed conversion ratio (FCR). Amino acid profiles of grass protein concentrate and soybean meal were comparable, with the latter having a slightly higher amount of total protein content, lysine and cysteine. The DFI and ADW indicated that the treatment diet was superior to the control. DFI for the treatment diet (1.512 kg/d) was 8% higher than the control diet (1.400 kg/d) by the end of the trial. Additionally, the ADW for the treatment diet was 6.44% higher than that achieved in the control sample. Meanwhile, FCR calculations indicated that the treatment diet is just as efficient as the conventional diet. Overall, the results of the study indicate positive potential for perennial ryegrass-derived green biorefinery protein concentrate as an alternative protein source for pig feed formulations in Ireland.

Brand owners can play a key role in enabling biobased products to penetrate mass markets and to influence consumer choices in relation to biobased products. The current paper explores the role that brand owners can play in supporting market uptake of biobased products and captures the perspectives of European brand owners in relation to biobased products. Based on the findings of this paper, brand owners have an overall positive outlook towards biobased products, with 85% of brands who don't currently use biobased ingredients or products within their branded products and 95% of brands who don't currently use biobased packaging interested in including these in future. However, brand owners still perceive some concerns surrounding biobased products including their high cost, functional performance and ease of integration, as well as their reliability of supply. Regional differences among brand owners have also been identified, with cost and uncertainty around customer demand appearing as a bigger issue in continental Europe, with functional performance concerns appearing as a more pressing issue for brands in northern Europe.

Global warming and climate change are imminent threats to the future of humankind. A shift from the current reliance on fossil fuels to renewable energy is key to mitigating the impacts of climate change. Biological raw materials and residues can play a key role in this transition through technologies such as anaerobic digestion. However, biological raw materials must also meet other existing food, feed and material needs. Green biorefinery is an innovative concept in which green biomass, such as grass, is processed to obtain a variety of protein products, value-added co-products and renewable energy, helping to meet many needs from a single source. In this study, an analysis has been conducted to understand the renewable energy potential of green biorefinery by-products and residues, including grass whey, de-FOS whey and press cake. Using anaerobic digestion, the biogas and biomethane potential of these samples have been analyzed. An analysis of the fertiliser potential of the resulting digestate by-products has also been undertaken. All the feedstocks tested were found to be suitable for biogas production with grass whey, the most suitable candidate with a biogas and biomethane production yield of 895.8 and 544.6 L/kg VS, respectively, followed by de-FOS whey and press cake (597.4/520.3 L/kg VS and 510.7/300.3 L/kg VS, respectively). The results show considerable potential for utilizing biorefinery by-products as a source for renewable energy production, even after several value-added products have been co-produced.
