THE IMPACTS OF LANDFILLING ORGANIC WASTE

Biogaz

At the landfill, putrescible materials decompose very slowly and release acid-laden water. Mixed with rainwater, this acidic juice (leachate) filters through the accumulated garbage and causes all kinds of contaminants (bacteria, chemical pollutants or heavy metals). Because of this phenomenon, the burial of garbage has a significant potential for groundwater and surface water pollution.

This anaerobic (oxygen-free) decomposition of organic matter is accompanied by an abundant production of biogas (a mixture containing large amounts of methane, a powerful greenhouse gas). That is why it is important to separate them at the source in order to treat them in an ecological way.

HOW DOES IT WORK?

Vermicomposting is a solution for those who want to reduce a good part of their household waste by transforming organic matter (food or garden waste) into compost. It is an innovative composting method and particularly suitable for apartments, because it is space-saving and odorless.

The vermicomposter consists of several bins, which receive organic waste (vegetable and fruit peelings, coffee grounds, eggshells, cartons, etc.) and worms.

The bins must be opaque to preserve the darkness necessary for earthworms and holes to let them through. These "composting worms" will digest organic waste several times and gradually transform it into compost ready to enrich indoor plants or for use in the garden.

They also produce a "vermithea" that can be diluted in water to create an excellent liquid fertilizer for plants.

Vermihea will always be used diluted. This is because it contains so much nutrient that it could be harmful to most plants. Before using your vermithe, dilute it to 1/10th, that is: 1 volume of vermithe in 9 volumes of water. It can be applied by watering or spraying.
