Frequently Asked Questions
What Is Organic Waste Or Biodegradable Waste?
Organic waste or biodegradable waste means waste of plant and animal origin. It includes kitchen waste including: tea leaves, egg shells, fruit and vegetable peels, cooked food scraps, meat and bones, garden waste including leaves and grass, carton waste, cardboard waste and paper waste
What Is Vermicomposting /Vermiculture?
Vermicomposting / Vermiculture is the accelerated and controlled decomposition of organic wastes, using composting worms and mesophilic bacteria active in the temperature range of 20°C to 45°C.
Is Vermicomposting An EST (Environmentally Sound Technology)?
Yes. It is an Environmentally Sound Technology (EST) according to the criteria defined by the United Nations Environment Program (UNEP). They define an EST as being less polluting, using resources in a sustainable manner, recycling more of their wastes and products and handling all residual wastes in a more environmentally acceptable way than the technologies for which they are substitutes. Vermicomposting has significant advantages over other waste disposal methods such as composting, landfill and incineration according to the criteria defined by the UNEP.
What Is The Difference Between Composting And Vermicomposting ?
Composting utilises bacteria for waste degradation. Waste reduction is 50%, No leachate treatment. Temperatures rise upto 65 to 70 degC. Recharging of bacteria culture required.
Vermicomposting utilises composting worms and bacteria. Waste reduction is 90%, solid and liquid fertilizer generated. Internal temperature is between 20-45degC. Recharging of worms not required for a well-run unit.
What Are The Various Types Of Vermiculture / Vermicompost Systems For Disposal Of Organic Waste?
Vermiculture / vermicompost systems can be classified into windrow based, pit based and continuous flow in-vessel systems.
What Kind Of Earthworms Are Used In The Digester? Can These Earthworms Process Both Vegetarian And Non-Vegetarian Food Waste?
The earthworms used in the Digester are surface burrowing earthworms’ also known as composting worms. These types of earthworms feed on rotting organic material. The composting worms used in the Digester are a blend of specially selected varieties of composting worms e.g. African Nightcrawlers (Eudrilus Eugeniae), Periyonix Excavatus and Eisenia Foetida – a blend of these composting worms is most ideal in Indian conditions. Through the vermiculture process all kinds of organic solid waste including vegetarian and non-vegetarian food is processed in the digester.
What Is The Processing Period For Conversion Of Waste Material Into Vermicompost In The Vermigold Tat-G Organic Digester?
The Vermigold Tat-G Digester has a very fast waste processing period of 7-14 days.
Is The Vermigold On-Site Waste Management System An Advanced Vermiculture Application?
Yes. The Vermigold Tat-G Organic Digester is a continuous flow in-vessel vermicompost system. It overcomes many of the drawbacks of traditional windrow / pit based vermicompost systems.
Are Vermigold Units The Right Size For Me?
The Vermigold Organic Digester comes in multiple capacities ranging from 50Kg/day to 2000 Kg/day and beyond. It is a modular system and can be expanded to process larger waste streams depending on customer requirements.
Where Can The Vermigold Waste Management Systems Be Installed?
We recommend the installation of our systems as near to the source of generation of waste as possible to reduce material handling or at a centralized location depending on customer preference. They can be installed in open areas, enclosed rooms or underground basements.
What Odours And Odour Controls Are Needed?
The Digester being an enclosed system, there is absolutely no chance of foul odours or the earthworms escaping provided prescribed procedures are adhered to.
What Happens If Foreign Non Organic Waste Such As Bottles, Plastic Or Cans Are Accidentally Introduced?
There is no harm done to the composting worms, however repeated contamination by foreign objects can affect the performance of the Vermigold Organic Digester. A service, whereby the lower section of removable mesh panels, must be removed and all foreign materials removed. This process is clearly described in the Digesters’ Support Manual.
What About Pests?
The Vermigold Tat-G Digester is not susceptible to invasion by cockroaches and rats, as its shape and internal environment are not conducive to habitation by pests. Rat / Insect Poisons can be placed safely inside the Vermigold Tat-G Digester with absolutely no threat to the compost worms should the need arise.
How Much Organic Fertilizer Will I Get From The System?
The vermicomposting process inside the Vermigold Tat-G Organic Digester reduces the quantity of waste input (feedstock) by a factor of 90%. So in fact if 100 kg of organic decaying waste is converted daily, then only 5-10 kg of converted vermicompost will fall to the collection trays. Along with the solid fertilizer, liquid fertilizer which is known as "vermiwash" is also generated.
Why Is The Vermigold Organic Waste Shredder Required To Assist The Digester?
The Vermigold Organic Waste Shredder is a specially designed shredder to process the organic kitchen, garden, paper and cardboard waste before introducing the waste material (feedstock) in the Organic Digester. Generally the smaller the size of the feedstock, the easier it is for the composting worms and mesophilic bacteria to eat the waste. Therefore we use the Vermigold Organic Waste Shredder to reduce the size of the feedstock and avoid foul odour which could occur if the size of the feedstock is not reduced.
