Waste Management In Action

Rapid optimal bioconversion of organic waste: Syntek

Syntek Environmental’s Ultraverte process can convert all kinds of waste into low volume, value added products. General Manager John Newton explains.

Over the last decade, Syntek Environmental has been focusing on technology and development to minimise the environmental impact of industrial and municipal wastewater and solid wastes.

Its Ultraverte bioconversion process tackles the later, providing an accessible and efficient solution for solid waste management.

While suited to multiple waste streams, John Newton, Syntek General Manager, highlights Ultraverte’s effective application to organic waste.

Ultraverte utilises naturally derived, synergistically linked bacteria strains to rapidly convert almost all kinds of organic waste into a free flowing, dry powder substance.

“The mass of waste material remaining after conversion is considerably less than the input mass, with over 95 per cent of organic matter converting to water vapour and inert biogas,” Newton says.

“The end product has wide applications such as a composting accelerator, soil bio-additive and spill absorbent.”

Ultraverte differs from the dehydration process as temperature during bioconversion is maintained at 25-35°C.

The temperature is largely maintained by heat generated by bacterial reactions. And, most bioconversion of organic waste is completed within 24 hours, compared to six to eight weeks in the composting process.

“A major environmental benefit of the Ultraverte bioconversion process is to avoid the production of odours and methane gas, which is bound to occur if the material becomes anaerobic or anoxic,” Newton explains.

“This is known to happen when organic waste is sent to landfill or for direct soil injection or surface land application. However, through Ultraverte, all pathogens present in the sludge are destroyed.”

According to Newton, additional benefits include a reduction in waste volume and weight, as well as onsite treatment, which results in a significant reduction in transport costs.

Ultravert technology has proven benefits in many applications, such as fruit and vegetable, putrescible waste with packaging, dairy cheese whey, cardboard converting and printing, cosmetics, paint, solvent and refinery crude oil.

“In fruit and vegetable waste processing, waste material has been converted into a dry granular material over a reaction time of 12-24 hours,” Newton says.

“The end product can then be returned to land as a soil additive for fruit, crop and vegetable growth. It also aids in maintaining moisture levels in the soil, with remaining bacteria aiding nutrient release.”

Furthermore, mixed municipal putrescible waste containing packaging such as cardboard and plastic can be treated and compacted for disposal, or plastic can be sieved from the organic product.

The plastic can then be recycled, with organic material used as a soil additive, Newton says.

  Ultraverte bioconversion equipment’s current capacity varies from 100 kilograms to 10 tonnes, and can be installed with multiple units on site to suit demand and specification.

“The operation has low energy inputs, minimal maintenance and operation requirements,”
Newton says.

“The Ultraverte process has been proven over 10 years of operation in hazardous waste conversion and is now changing industry practice in organic waste treatment.”
