“…Food loss occurs in production, storage, transport, and processing, which are the stages of the value chain with the lowest returns. Organic waste biorefinery is a concept for waste management which can extract high value products from organic waste and technological, strategic and market constrains may affect implementation (Alibardi et al, 2020). Organic waste fertilization which might be an alternative for mineral fertilizers, promoted soil biochemical and microbial properties (Gryta et al, 2019).…”

Food loss may occur in production, storage, transport, and processing, which are the stages of the value chain with the lowest returns. The current searching was done by the keywords in main indexing systems including PubMed/MEDLINE, Scopus, and Institute for Scientific Information Web of Science as well as the search engine of Google Scholar. The most important points challenging areas that represent opportunities for stakeholders to look into in China are, put in place suitable economic incentives to encourage restaurants to get more involved in the formal system, create a comprehensive regulation system to benefit all relevant stakeholders by clearly defining their respective roles and responsibilities, which is necessary for the proper functioning of the whole system. In China, the most important regulations, policies and plans are regulations on safety issues of food waste treatment, detailed countermeasures on organizing, educating, supervising, and inspecting the work on food waste reduction in China, and detailed plant for household waste collection and treatment, issued by Chinese government, state council, and ministry of environmental protection. Setting national goals, awareness-raising campaigns, strict and appropriate regulation, stakeholder engagement, biorefinery and food waste recycling to animal feed are important strategies for better waste management. The most important food waste management practices in China are source separation, animal feed, rendering, composting, co-digestion, anaerobic digestion, incineration, landfill, and etc. Understanding social factors influencing household behavior is utmost importance; public education and specific communication highly contribute to improve recycling.

“…Biorefineries' environmental and economic performance depends on the feedstock, logistics, process configuration, integration with nearby industries, and management of byproducts [12,42]. Extracting high-value products from biobased materials may be hard to implement on a large-scale in a way that is also economically and environmentally efficient [12].…”

“…Nevertheless, biogas solutions are arguably always relevant to the drive toward a circular economy even when the bio-based materials are highly utilised and valorised. This partly because there will always be some low-grade wastes or by-products leftovers that can be effectively managed through anaerobic digestion [42] and energy balance of biorefineries may improve as well [45]. But, more importantly and in a broader sense, a circular economy cannot be achieved by merely non-biobased processes: closing the loops through biological processes and regeneration through technologies such as anaerobic digestion is an essential part of a circular and biobased economy [46].…”

The transition toward a circular and biobased economy requires the biorefineries and bio-based industries to become more resource efficient with regards to their waste and by-product management. Organic by-products and waste streams can be an important source of value if used in feasible pathways that not only have a low environmental impact but also preserve or recover their energy, nutrients, and other potentially valuable components. Through development of a multi-criteria assessment framework and its application on a real case, this article provides methodological and practical insights on decision making for enhanced by-product management. Our framework includes 8 key areas and 18 well-defined indicators for assessing the environmental performance, feasibility, and long-term risk of each alternative. We studied six different management options for the stillage by-product of a Swedish wheat-based biorefinery and our results shows that the most suitable options for this biorefinery are to use the stillage either as animal fodder or as feedstock for local biogas production for vehicle fuel. This multi-criteria approach can be used by bio-based industrial actors to systematically investigate options for by-product management and valorisation for a circular and bio-based economy.

“…This equation can be reversed by designing more effective recovery and processing systems to turn organic waste into a source of value and contribute to restoring natural capital. Biorefineries could be a central technology in this endeavor (Alibardi et al, 2020). Operating in a similar way to petrochemical refineries, they employ a range of techniques -such as feedstock pretreatments, biological processes, enzymat-ic conversions -to transform source separated biowaste into valuable chemicals, products and energy.…”

This innovative Biorefinery platform is based on the integration of a mild thermal pre-treatment and a solid/liquid separation unit to parallel-integrated bioprocesses specifically selected on food waste distinctive chemical composition: a liquid fraction, rich in readily fermentable sugars, to be transformed into valuable biobased products, and a solid organic residue to enhance biomethane production generating a fully hygienized digestate to be recycled. The preliminary results in terms of VFAs yields and composition from the acidogenic stage, and the methane conversion rate from the anaerobic digestion of the solid residue, are here presented
