The utilization of organic wastes to improve soils or for growth media components in local farms and nurseries can reduce the environmental pollution linked to waste disposal while increasing the sustainability of crop production. This approach could be applied to waste products generated from the production of guacamole (an emerging activity in the avocado production areas in mainland Spain), ...

This paper presents a spatially explicit method for making regional estimates of the potential for biogas production from crop residues and manure, accounting for key technical, biochemical, environmental and economic constraints. Methods for making such estimates are important as biofuels from agricultural residues are receiving increasing policy support from the EU and major biogas producers,...

The global food system is and will be facing many challenges in the coming decades, which necessitate innovative solutions to address issues of a diminishing fertilizer supply, an increasing demand from growing populations, frequent extreme climates due greenhouse gas emissions. An advancement proposed synthesizing waste, here referred as waste anaerobic digestate (FWAD). This occurs through pr...

Developing commercial mushroom and vegetable production in an integrated food-to-waste-to-food biosystem VegWaMus CirCrop aims to develop into biosystem. The objective is close the loop between food waste-based biogas reuse of output after anaerobic digestion. Integrated cultivation interesting from a circular approach; organic wastes are utilised for energy crop closed system.

This Special Issue of Bioresource Technology is dedicated to selected contributions presented at the international Workshop: ‘‘Livestock waste treatment systems of the future: A challenge to environmental quality, food safety, and sustainability,” held 2–4 April, 2008, in Florence, South Carolina (USA) and sponsored by the OECD (Organisation for Economic Co-operation and Development), Cooperati...

Vermicomposts have been shown to promote the germination, growth, and yields of plants. This paper aims to demonstrate the effects of vermicomposts produced from three types of wastes on growth and flowering of petunias which are an important U.S. flowering crop. Vermicomposts, produced commercially from cattle manure, food wastes and paper wastes, were substituted at a range of different conce...
