Your partner in waste recovery and recycling

WTT is proud to serve clients around the world, however global logistics challenge our core value of reducing the company’s carbon footprint. Due to the consistent growth of international clients we have chosen to move away from a single point of engineering and production. 

“In 2018 we opened our Australian branch office
with experienced staff being local on the ground and a chain of
contractors in place to provide cost effective solutions.”

According to current growth pattern, Australia is set to reach a population of about 38 million by 2051. The effects waste has on our planet is increasingly more evident. As the complexity of waste streams evolve, the management of waste needs to adapt. “Reduce, Reuse, Recycle” has never been more important. 


Australian agriculture soils are increasingly deficient in nutrients and organic carbon. The compost produced from processing all available organics across Australia would cover less than 0.5% of the compost requirements in Australian agriculture, showcasing close to infinite market opportunities.

WTT has over 20 years of experience composting FOGO, as it became nationwide mandatory in the Netherlands back in 1994. There isn’t a one-size-fits-all model, WTT is your partner for cost effective tailor-made solutions.

Energy from waste

Our in-house engineered Dry-Anaerobic Batch Digestion (dry AD) technology enables biogas extraction as a pre-step towards final composting. Enabling waste operators to extract the gas potential and upgrade it to electricity, heat and/or natural gas, without compromising on Australian compost standards.

Electricity and heat can be used to neutralize the facilities demand and commercially sold to offset any excess. Biogas upgraded to Bio-methane can be injected into the grid or used as an alternative fuel in, for instance, waste collection vehicles.

Track record

As of today, WTT has delivered over 120 comprehensive waste treatment facilities all over the world. These facilities include, but are not limited to; Pre-treatment / decontamination, Composting, Dry Anaerobic Digestion, Bio-drying, RDF Production, Post-treatment / Refining, facility air and water management. We’ve built over 1200 In-Vessel Composting tunnels with an estimated combined processing capacity of over 7.280.000 tons per annum. After pre-treatment only ca. 50% of Municipal solid waste ends up at composting tunnels, meaning that these facilities accept over 14 million tons per annum through the gate.

A fun waste fact, but also showcasing WTT’s experience, is that in accordance to the Australian national waste report of 2016, WTT’s total installed processing capacity exceeds the total amount of Municipal Solid Waste generated in Australia.

Proven technology

WTT Netherlands was founded in 1996. The Netherlands is one of the leading countries in waste management worldwide. WTT is the partner to implement state of the art and cost-effective solutions that have been developed and carefully improved over the last 20 years.
