Composting, in general, is the natural way of putting back nutrients into the eco-cycling system and approximately 30 % of the municipal solid waste can be composted and recycled into a nutritious topsoil additive.
On-site composting efficiently takes care of the organic waste at the source of generation.
On-site processing of food organics produced by the institutional, commercial and industrial sector has a number of economic and environmental benefits over all other options, like landfill disposal, incineration, centralized composting or production of biogas:
- The elimination on-site of a waste fraction which induces several environmental inconveniences, such as insanitary handling, health problems for the collection staff, spreading of fungal spores, spreading of leachate into the ground water and disagreeable odours.
- A reduction of the waste collection frequency, which leads to substantial reductions of the waste collection costs, disposal fees and costly transports.
- The elimination of the need for centralised organics processing facilities and therefore a reduction of greenhouse gas emissions and impacts on urban amenity from waste collection and transport activities.
- A reduction of the waste combustion (incineration), which generates 75 % of the total dioxin emissions in the world.
- The transformation into a composted material, which is much more easy, hygienic and economic to store, handle and transport than the untreated waste.
- A weight reduction of approximately 90 %.
- A waste volume reduction of at least 75 %.
- The opportunity to recycle the waste into a valuable product – compost – that can be used to maintain and fertilize the landscaped environment.
- The opportunity to considerably reduce CO2 emissions.
