ORM Worm Digesters

Concept of Worm Digestion

It handles Biodegradable Waste
It uses Livestock – Worms
It allows Waste to be handled on site
It impacts on Landfill Costs
It produces an Organic Growing Media
It encourages Recycling

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).

A Worm Digester is constructed according to what most suit your requirements , depending on

a) volume of waste available
b) location

Site Requirements

You will need a consistent & sustainable waste stream (Catering Waste – Biodegradable Waste).
Have a designated person responsible for waste handling.
Install a system for handling, separating and moving waste from bins & bags to your worm digester.
Have a method of shredding waste or use an ORM macerator
Make Use of the created organic matter.

Extra's
Single/Three Phase Power Supply (dependant on size).

Essential Needs

Critical Factors – Requirements

Correct Volumes of Food – Not too much
Moisture – Water Supply
Oxygen – Air Supply included
Designated personnel – Monitoring

Waste Handling

Waste should be handled in bins (if possible).
Waste must be shreaded or chopped into small pieces.
Waste should be spread evenly across the worm bed in strips leaving 30% of the surface area uncovered by food.
Largest variety of food waste give best results.
Critical to monitor moisture level.

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.
