Vermicompost ( vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. This process is called vermicomposting, with the rearing of worms for this purpose is ...
Food recovered by food waste critic Robin Greenfield in Madison, Wisconsin, from two days of recovery from dumpsters [1]. Food loss and waste is food that is not eaten. The causes of food waste or loss are numerous and occur throughout the food system, during production, processing, distribution, retail and food service sales, and consumption.
This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms. Waste can be solid, liquid, or gases and each type has different methods of disposal and management.
Biodegradation is the naturally-occurring breakdown of materials by microorganisms such as bacteria and fungi or other biological activity. [ 35] Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. [ 36] The predominant difference between the two is that one process is naturally-occurring ...
Waste (management) hierarchy is a tool used in the evaluation of processes that protect the environment alongside resource and energy consumption from most favourable to least favourable actions. [ 1] The hierarchy establishes preferred program priorities based on sustainability. [ 1] To be sustainable, waste management cannot be solved only ...
The global blue water footprint of food waste is 250 km 3, the amount of water that flows annually through the Volga or three times Lake Geneva. [197] There are several factors that explain how food waste has increased globally in food systems. The main factor is population, because as population increases more food is being made, but most food ...
Compost is a mixture of ingredients used as plant fertilizer and to improve soil 's physical, chemical, and biological properties. It is commonly prepared by decomposing plant and food waste, recycling organic materials, and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes ...
Food webs depict energy flow via trophic linkages. Energy flow is directional, which contrasts against the cyclic flows of material through the food web systems. [34] Energy flow "typically includes production, consumption, assimilation, non-assimilation losses (feces), and respiration (maintenance costs)."
