“…Coffee and soya beans are major agricultural products with 9 million metric tons of green coffee beans and 313 million metric tons of soya beans produced in 2016 worldwide [ 1 , 2 ]. The hulls or chaff from these products are low-value agricultural wastes which go to landfill when an agricultural use does not exist [ 3 , 4 ]. A promising use of this potential waste product is in the generation of biocarbon for composite applications as a bio-based replacement for mineral fillers such as glass fibre and talc [ 5 , 6 ].…”

The physical properties of biocarbon vary widely with the biomass used, and the temperature and duration of pyrolysis. This study identifies the effects of feedstock characteristics and pyrolysis conditions on the production of biocarbon and the corresponding properties for industrial applications. For coffee chaff and soy hulls, ash content and carbon content increased with pyrolysis temperature and duration. Ash content increased thermal conductivity and specific heat, and decreased electrical conductivity. Change in surface area with pyrolysis conditions was dependent on type of feedstock. Increased surface area corresponded with increased thermal and electrical conductivity. Increased carbon content corresponded with increased graphitization and thermal stability and decreased surface functionality. Properties of soy hull biocarbons were found to be similar to the properties of other biocarbons with industrial applications such as incorporation into polymer composites.

Wastewater from the food industry is increasingly recognized as a valuable source of energy and as a resource for new products and not as waste. The reutilization and valorization of wastewater contributes to combating water scarcity and to improve the energetic efficiency of treatment facilities. Moreover, it has the added benefit of reducing environmental impact and providing economically interesting added value products. This review discusses the most recent approaches for the valorization of food industry wastewaters of different origins (dairy, brewery, oil mill, fish, meat, among others) and the products obtained, from energetic resources such as biogas and biofuel to the recovery of biopolymers, pigments, phenolic compounds, and other added value products. A critical overview regarding the bottlenecks of large-scale implementation of resource recovery strategies, including up-scaling, quality and quantity of the effluent, legislation, and economic, environmental, and social issues related to the use of products derived from waste, is herein presented.
