Domestic sewage vermifilter showing accumulated contents (composting worms exposed) A vermifilter (also vermi-digester or lumbrifilter) is an aerobic treatment system, consisting of a biological reactor containing media that filters organic material from wastewater.
Vermicompost can be mixed directly into the soil, or mixed with water to make a liquid fertilizer known as worm tea. The light brown waste liquid, or leachate, that drains into the bottom of some vermicomposting systems is not to be confused with worm tea. It is an uncomposted byproduct from when water-rich foods break down and may contain ...
Vermifilter toilet, also known as a primary vermifilter, vermidigester toilet, tiger toilet [1] [2] or tiger worm toilet, [3] is an on-site sanitation system in which human excreta are delivered from a toilet (usually by flushing) onto a medium containing a worm-based ecosystem.
Vermicomposting can take place indoors or outdoors. However, it is recommended to keep the worm bin indoors since worms can die from extreme temperatures. [2] Vermicomposting is faster (2–3 months) than no-worm composting (3–9 months), involves minimal maintenance, limits odor, and provides multiple nutrients to the soil. [16]
Windrow turner used on maturing piles at a biosolids composting facility in Canada. Maturing windrows at an in-vessel composting facility.. In agriculture, windrow composting is the production of compost by piling organic matter or biodegradable waste, such as animal manure and crop residues, in long rows – windrow.
Green waste does not include things such as dried leaves, pine straw, or hay. Such materials are rich in carbon and considered "brown wastes," while green wastes contain high concentrations of nitrogen. Green waste can be used to increase the efficiency of many composting operations and can be added to soil to sustain local nutrient cycling.
A sewage farm in Hampshire, England. The resources available in wastewater and human excreta include water, plant nutrients, organic matter and energy content. Sanitation systems that are designed for safe and effective recovery of resources can play an important role in a community's overall resource management.
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes.
