Would you like your business to be more “environmentally responsible” and recycle your organic waste on-site? Using worms, organic waste can be transformed into soil friendly plant nutrient. Benefits to the environment are : great reductions in the level of methane gas and carbon dioxide (compared to landfill) and reductions in waste removal costs. Schools and homes are becoming involved nationwide and now the technology and service is here for easy on- site organic waste recycling for businesses. Businesses are advised to undertake a waste audit of their organic waste and Organic Waste Solutions (WORMSRUS) can provide a consultancy assessment on the volume and waste types identified for recycling.

Recommendations for suitable systems to suit your needs will be advised upon the waste audit results. Here is our range of commercial worm digesters that are available in New Zealand. Our digesters are capable of digesting medium to large volumes of organic waste on a daily basis.  The systems function by the continuous flow of organic material placed in the top, with the worm castings and liquid fertiliser being easily removed from the bottom.

Tat-G On Site Organic Digester
The Tat-G On-Site Digester is a worm driven organic waste recovery system manufactured in Australia by Tat-G Corp Pty and solely distributed in New Zealand by Organic Waste Solutions Ltd ( WORMSRUS).
The Tat-G design objectives are to eliminate waste removal from site and shift from a waste focus to a resource focus producing a quality value added product.

Tat-G On Site Organic Digester Tat-G On Site Organic Digester

The On-Site Digester differs from traditional vermiculture methods by using the latest technology that includes a compact design within a high surface working area.  The Tat-G On-Site Digester’s 3-dimensional concept has a small footprint whilst providing a large surface area with multiple cells, enhancing the oxygenation of material.  The external panels allow easy access for inspection and maintenance.  The worm castings are automatically collected in trays.  The liquid fertiliser is easily pumped for collection as a concentrate then diluted as a valuable natural plant nutrient.

The digester operates by solar power or reduced mains power. A battery provides two weeks of back up power.  The power operates a quality submersible pump for the liquid reticulation system that is controlled by an electronic timer. This is adjustable for seasonal conditions.

The manufacturer has recently incorporated the above technology to increase the product range and now produces a single, plus modular unit and an industrial modular system.  All systems are made to be durable, odour friendly and are backed by a 24-month warranty on structural components and workmanship with 12 months warranty on electrical and plumbing system components.
