THE IMPACTS OF LANDFILLING ORGANIC WASTE
At the landfill, putrescible materials decompose very slowly and release acidic water. When mixed with rainwater, this acidic juice (leachate) filters through the accumulated garbage and carries with it all kinds of contaminants (bacteria, chemical pollutants or heavy metals). Because of this phenomenon, landfilling of garbage has a significant potential to pollute groundwater and surface water.
This anaerobic decomposition (without oxygen) of organic matter is also accompanied by the production of abundant biogas (a mixture containing large quantities of methane, a powerful greenhouse gas), which is why it is important to separate it at the source in order to treat it in an environmentally friendly manner.
HOW DOES IT WORK?
Vermicomposting is a solution for those who wish to reduce a large part of their household waste by transforming organic matter (food or garden waste) into compost. It is an innovative composting method that is particularly suited to apartments, as it takes up little space and is odorless.
The vermicomposter consists of several bins, which receive organic waste (vegetable and fruit peelings, coffee grounds, egg shells, cardboard, etc.) and worms.
The bins must be opaque to keep the darkness necessary for the earthworms and have holes to let them through. These "composting worms" will digest the organic waste several times and transform it little by little into compost ready to enrich indoor plants or to use in the garden.
They also produce an "wormhole" that can be diluted with water to create an excellent liquid fertilizer for plants.
Before using your vermicompost, dilute it 1:10, that is: 1 part vermicompost in 9 parts water. It can be applied by watering or spraying.
