Composting Food waste

food waste can biodegraded composting, , reused fertilize soil. composting aerobic process completed microorganisms in bacteria break down food waste simpler organic materials can used in soil. redistributing nutrients , high microbial populations, compost reduces water runoff , soil erosion enhancing rainfall penetration, has been shown reduce loss of sediment, nutrients, , pesticide losses streams 75–95%.
traditional composting uses microbes perform decomposition, process efficient using low, mid, , high temperature microbes (psychrophilic, mesophilic, , thermophilic – respectively). high temperatures required thermophilic microorganisms hot enough kill pathogens, making product of traditional composting satisfactory use in soil according united states environmental protection agency s (epa) standards. traditional decomposition process requires long length of time , additional energy expended turn material , maintain aerobic process. composting thermophilic microbes can lead nutrient loss , compost product heterogeneous, potential higher levels of contaminants can harmful if used in agriculture. alternate method of composting vermicomposting.
vermicomposting practise of feeding scraps worms produce fertilized soil byproduct. process of composting using earth worms completed in short duration of time , requires no additional energy turn , maintain aerobic processes, these actions performed worms. in order keep worms alive, environment has kept below 35° celsius, therein making compost ineligible use in agriculture according epa standards. product of vermicomposting homogenous , contains lower levels of contaminants traditional composting. integrate vermicomposting , traditional composting in effort maximize efficiency while producing high quality organic product can used in agriculture.
composting food waste leads decrease in quantity of greenhouse gases released atmosphere. in landfills, organic food waste decomposes anaerobically, producing methane gas emitted atmosphere. when biodegradable waste composted, decomposes aerobically , not produce methane, instead producing organic compost can utilized in agriculture.
municipal food waste (mfw) can composted create product of organic fertilizer, , many municipalities choose citing environmental protection , economic efficiency reasoning. transporting , dumping waste in landfills requires both money , room in landfills have limited available space. 1 municipality chose regulate mfw san francisco, requires citizens separate compost trash on own, instituting fines non-compliance @ $100 individual homes , $500 businesses. city s economic reasoning controversial mandate supported estimate 1 business can save $30000 annually on garbage disposal costs implementation of required composting.
food waste can composted @ home, avoiding central collection entirely, , many local authorities have schemes provide subsidised composting bin systems. however, proportion of population willing dispose of food waste in way may limited.
