“…In this context, the biggest challenge of the scientific world is to develop efficient valorization strategies with a high degree of industrial feasibility [56]. In prioritizing resource efficiency, the closed-loop value chains that convert waste and byproducts into resources can lead to the achievement of a sustainable food system in all its three dimensions: economic, social, and environmental protection [23,57]. In this context, the management of food byproducts is encouraged to move from a linear model to a much more complex circular chain.…”

One of the biggest challenges in managing the food sector during a pandemic crisis is sustaining a robust food security system and adopting the right strategies in correlating the consumers’ needs and requirements with those of food safety, the producers, the distribution chain, the economic environment, and waste management. The restrictions on people’s global movement, commodities, and services and the measures taken to reduce the spread of COVID-19 have disrupted food environments around the world and forced us to collectively redesign and optimize our systems using existing resources from a more sustainable perspective. This paper offers an overview of the implications of COVID-19 for the food supply chain and discusses several potential strategies for tackling short- and long-term adverse effects resulting from the pandemic.

“…For example, new packing materials are increasingly composite materials (the mixture of several materials designed for desired properties). Composite waste materials are challenging to effectively recycle when the mechanical separation is applied [ 2 ]. Thus, new technologies are needed to sustainably treat MSW in the context of zero landfilling and circular economy goals.…”

Lab-Scale Study of Temperature and Duration Effects on Carbonized Solid Fuels Properties Produced from Municipal Solid Waste Components

In work, data from carbonization of the eight main municipal solid waste components (carton, fabric, kitchen waste, paper, plastic, rubber, paper/aluminum/polyethylene (PAP/AL/PE) composite packaging pack, wood) carbonized at 300–500 °C for 20–60 min were used to build regression models to predict the biochar properties (proximate and ultimate analysis) for particular components. These models were then combined in general models that predict the properties of char made from mixed waste components depending on pyrolysis temperature, residence time, and share of municipal solid waste components. Next, the general models were compared with experimental data (two mixtures made from the above-mentioned components carbonized at the same conditions). The comparison showed that most of the proposed general models had a determination coefficient (R2) over 0.6, and the best prediction was found for the prediction of biochar mass yield (R2 = 0.9). All models were implemented into a spreadsheet to provide a simple tool to determine the potential of carbonization of municipal solid waste/refuse solid fuel based on a local mix of major components.

“…The misconception of industrializing food and agriculture has resulted in extreme environmental degradation and destruction (Campbell et al, 2017;Willett et al, 2019). Failure to recycle the nutrients used in agriculture production is striking (Buckwell and Nadeu, 2016;Sherwood, 2020). The present system is highly dependent on external and excessive energy inputs, especially in the form of fossil fuels (Sherwood, 2020).…”

Critics of modern food systems argue for the need to shift from a consolidated and concentrated, often monoculture based agro-industrial model toward diversified, post-fossil, and nutrient recycling food systems. The abundance of acute and obvious environmental problems in the agricultural subsystems of the broader food system(s) have resulted in a focus on technological and natural scientific research into "solving" these point of production problems. Yet, there are many facets of food systems that are vital to sustainability which are not addressed even if the environmental problems were solved. In this article, we argue for agroecological symbiosis (AES) as a generic arrangement for re-configuring the primary production of food in agriculture, the processing of food, and development of a food community to work toward system-level sustainability. The guiding principle of this concept was the desire to base farming and food processing on renewable bioenergy, to close nutrient cycles, to break away from the consolidated food chain, to be more transparent and connected with consumers, and to revitalize the rural spaces where farms generally operate. Through a consistent and robust collaboration and co-creative process with transdisciplinary actors, ranging from food producers, and processers to policy actors, we designed a food system model based on networks of AES (NAES). The NAES would form place-based food networks, replacing the consolidated commodity chains. The NAES supports sustainable interactions from a biophysical and socio-cultural perspective. In this paper, we explain the AES concept, give an overview of the process of co-creating the pilot AES, and a proposal for the extension of the AES, as NAES, to create sustainable food systems. Overall, we conclude that the AES model holds potential for creating place-based food systems that further the sustainability agenda.
