This article aims to understand the role of institutions, especially meso-institutions, in the construction of definitions of bioplastics that foster sociotechnical changes, so that a single language with epistemic quality can be defined for global governance in the solution of environmental problems arising from the plastic production chain. To th...

Food waste is a global concern that urges the development of multiple strategies to be tackled. Food waste-reducing platforms (FWRP) have emerged as a technological solution in different countries, connecting different parties along the food supply chains to reduce waste by redistributing surplus or non-commercial food. However, most studies refer...

Environmental and social impacts caused by petrochemical plastics are generating significant concerns on a global scale. Bioplastics can contribute to the transition to more sustainable materials, but they did not expand at the expected rates in the early 2000s. With recent predictions indicating that the bioplastic capacities will almost triple in...

Food waste is one of the main obstacles to transitioning to sustainable and circular food systems. Food waste-reducing platforms (FWRPs) have emerged as low-cost alternatives by donating or commercializing surpluses and non-commercial food. However, as a recent phenomenon, little is known about their actual contribution to the fight against food wa...

The leachate treatment by nanofiltration (NF) process has received much attention over the last two decades. Previous studies focused on the investigation of the technical feasibility of NF. However, there are a limited number of works that examined leachate treatment costs. On the other hand, in a landfill management system, the economic component...

Leachate treatment is a major issue in the context of landfill management since solutions have not been yet developed, resulting in more satisfactory technical and economic results concerning leachate treatment. In this paper, the technical and economic factors concerning lime application and nanofiltration for the treatment of leachate from the Se...

Among the most promising opportunities to tackle food waste are the food waste reducing apps. Contrary to what some entrepreneurs and policy makers may initially believe, the challenges are not limited to the technology, so their attention should be extended to a business perspective. Focussing on non-technological aspects, de Almeida Oroski explor...

One of the main problems related to solid waste landfilling is the effective treatment of leachate liquids produced in landfills. The physicochemical composition of these leachates is strongly influenced by the nature of the landfilled waste, the water balance, the mode of operation of the site and the age of the site (El-Fadel el al., 2002). For t...

Landfill leachate consists mostly of a high content of refractory organic matter, ammonia and toxic compounds. All these compounds, regardless of their nature, have a potential pollution effect on local ground and surface waters. In this context, the purpose of the present study was to evaluate a treatment process (coagulation–flocculation with lim...

One of the main problems related to solid waste management is the effective treatment of leachate liquids produced in sanitary landfills. In this context, the objective of the present study was to evaluate coagulation-flocculation with lime coupled by nanofiltration (NF) in the treatment of landfill leachate from Seropédica, located in the Rio de J...

This paper proposes a framework with six dimensions that can be useful to evaluate the potential and the stage of a bio-based platform chemical. The framework considers technological and strategic challenges to be filled by a company that intend to lead a platform based on a bio-based chemical. A platform chemical should be an intermediate molecule...
