“…In addition, with short-chain volatile fatty acids obtained from the degradation of organic waste, such as acetic acid, valeric acid, propionic acid or butyric acid, C. necator is also able to produce PHBV. In this way, Hathi and coworkers studied the production of PHBV by C. necator valorising food waste hydrolysate and VFAs as PHBV inducers (Hathi et al, 2022). They showed that the fermentations combining food waste hydrolysate with valeric acid produced the highest yield of PHBV (34.12%) per total amount of biomass and the highest molar 3HV content (50%) (Hathi et al, 2022).…”

The use of food waste derived VFAs as the sole carbon source for PHBV batch production was also analysed reporting a yield of 1.02 g/L PHAs (Vu et al, 2022).…”

Global concern about plastic pollution is forcing new policies and modifications of human consumption as well as promoting new research lines aiming at the replacement of non-degradable plastics with other polymers more environmentally friendly. Addressing food waste and promoting circular economy strategies, among other approaches, are crucial in reducing environmental impacts and fostering sustainability in several sectors like the agri-food industry. The European Union’s Circular Economy Action Plan is a significant initiative in this direction. Biotechnological processes, especially the valorisation of agri-food waste to produce highly marketed biomolecules like poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) using microorganisms as cellular factories, offer promising avenues for achieving these goals. PHBV is a biodegradable polymer firstly characterised as an isolated biopolymer from bacterial biomass. This biopolymer shows interesting physicochemical properties making possible immense potential in various applications due to its biocompatibility and sustainability, thus revealing it as a good candidate to replace plastics produced by chemical synthesis from petroleum (which are highly recalcitrant and consequently pollutants). This review critically analyses the PHBV synthesis and end-of-life scenarios from their synthesis using chemical and biological pathways, through the forms of biotechnological operation and production, to the forms described until the moment of recycling.

“…PHA's improved physico-chemical qualitiesfor instance, in comparison to PP-have encouraged its use in a variety of industries, particularly fine chemicals, pharmaceutical industries, and food packaging material. Numerous investigations have been carried out in an attempt to discover low-cost feedstocks that can be used on a larger scale than standard raw materials [90]. Agro-industrial waste (such as lignocellulosic waste from the food industry and forestry) has received a great deal of attention among many of the multiple substitute feedstocks for PHA production because food waste offers a tactical way to reduce the ultimate manufacturing cost.…”

“…As only eight years are left to attain this target, there is an urgency to scale up action to lessen the food waste [106][107][108][109]. Reducing the food waste provides an opportunity for instantaneous climate benefits and making our food systems overall sustainable-a obligatory revolution to safeguard this planet and to assure sustainable nutritional outcomes [7,90,110]. Food waste utilization not only aid towards sustainable environment but also provide nutritional and food & energy security [111][112][113][114][115][116][117][118][119][120][121][122][123][124].…”

There is world-wide generation of food waste daily in significant amounts, leading to depletion of natural resources and deteriorating air quality. One-third of global food produced is wasted laterally with the food value chain. Carbon footprint is an efficient way of communicating the issues related to climate change and the necessity of changing behavior. Valorization or utilization of food wastes helps in resolving issues related to environment pollution. Reduction in the carbon footprint throughout the chain of food supply makes the whole process eco-friendly. Prevailing food waste disposal systems focus on their economic and environmental viability and are putting efforts into using food waste as a resource input to agriculture. Effective and advanced waste management systems are adopted to deal with massive waste production so as to fill the gap between the production and management of waste disposal. Food waste biorefineries are a sustainable, eco-friendly, and cost-effective approach for the production of platform chemicals, biofuels, and other bio-based materials. These materials not only provide sustainable resources for producing various chemicals and materials but have the potential to reduce this huge environmental burden significantly. In this regard, technological advancement has occurred in past few years that has proven suitable for tackling this problem.
