Understanding food waste-reducing platforms: A mini-review.

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 waste.

Nanofiltration applied to the landfill leachate treatment and preliminary cost estimation.

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.

Evaluation of coagulation-flocculation and nanofiltration processes in landfill leachate treatment.

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 lime coupled with nanofiltration) applied to landfill leachate from Seropédica, Rio de Janeiro (Brazil).

Developing new platform chemicals: what is required for a new bio-based molecule to become a platform chemical in the bioeconomy?

This paper proposes a framework with six dimensions that can be useful for evaluating the potential and the current stage of a bio-based platform chemical. The framework considers the technological and strategic challenges to be fulfilled by a company that intends to lead a platform based on a bio-based chemical. A platform chemical should be an intermediate molecule, with a structure able to generate a number of derivatives, that is produced at a competitive cost, capable of allowing exploitation of the scale and scope economies, and inserted within a complete innovation ecosystem that is able to create value with governance mechanisms that are capable of allowing coordination of the innovation process and facilitation of the value capture by the focal company leading the platform, in our case the producer of the platform molecule.
