The Workers

We use Dendrobaena Veneta worms in our Worm digestion systems, they will consume up to 80% of their body weight per day and produce a 100% organic material for use elsewhere.

Worms are able to digest ~ Ordinary kitchen waste such as peelings, cooked and uncooked scraps, teabags, eggshells, paper kitchen towels, even shredded newspaper etc. In fact virtually any organic kitchen waste (a more extensive list is available upon request).

    The Vermicomposting process

    • Vermicomposting uses particular species of earthworms to process organic wastes into material possessing excellent chemical, physical and biological characteristics for improving plant growth and health.
    • During the vermicomposting process, organic matter is fully oxidised and stabilised and the nutrients are converted into readily available forms for plants.
    • Vermicomposts have a fine structure, high moisture-holding capacity, greatly increased microbial activity and contain growth regulators produced by micro organisms and the interaction with humic substances.
