Plastics materials are essential in every part of our lives, resulting in their increasing production and consumption. Consequently, recycling of plastics has been of great importance in the last decades. Among all types of plastics, polyesters have become very appealing for numerous kinds of applications, making their recycling crucial. Several techniques have been developed for the recycling of plastics with the aim of eliminating the waste accumulated, as well as to create a circular economy.

The article discusses the production of platform chemicals from various biological sources, including glycerol, lignin, cellulose, bio-oils, and sea products. It presents the results of catalytic and downstream processes involved in the conversion of these biomass-derived feedstocks. The experimental approaches are complemented by numerical descriptions, ranging from density functional theory (DFT) calculations to kinetic modellingof the experimental data. This multi-scale modelling approach helps to understand the underlying mechanisms and optimize the production of platform chemicals from renewable resources.

With the global population projected to reach close to 10 billion by 2050, the escalating demand for cereals such as wheat, rice, corn, oat, and barley places significant pressure on production systems. These systems are increasingly vulnerable to the adverse impacts of climate change, threatening global food security. This article emphasizes the critical need to address these challenges and explores strategies for sustainable foodproduction, focusing on the opportunities that the upcycling of cereal byproducts offers for human and animal nutrition and health.

The Paris Agreement has made combating climate change a priority and has incentivised innovationfor the greentech industry. Higher education institution[s] (HEI[s]) play an important role in fueling this innovation by developing disruptive technologies and support the creation of start-up companies that take the risk to bring these technologies to the market. The successful spinning out of such start-ups relies on the HEIs nurturing anecosystem with multiple actors as well as internal mechanisms to transfer such technologies to the start-up. HEIs have dedicated offices involved in technology transfer (TTO) that provide an interface between all the different actors (inventors, founders, start-up, investors, etc.). The TTO of an HEI also plays a central role in the technology transfer by providing the licence agreements granting start-ups the rights to use a technology developed by the HEI. This review summarises the role of a TTO and the practice of making the licensing process as transparent as possible for start-up founders and investors.
