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.

- 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.
- Progress project – requires a site visit.
- Evaluate Waste Source – Volume and make up.
- Calculate space and livestock requirements.
- Produce detailed presentation.
