Design + Build
Every waste treatment project we work on is unique. We offer turnkey design and build projects for organic waste treatment facilities, with a focus on source separated municipal organic waste. We have designed and build over 120 facilities all over the world. Our solutions are built on extensive know-how and many years of experience. We strive to maximize cost efficiency and focus on customer needs. In addition, our solutions are sustainable aimed at preserving finite natural resources and reduction of greenhouse gas emissions.
We Think Ahead
We are committed to delivering quality throughout our cycle of service. We specialize in solid preparation and strive to anticipate our customers’ critical requirements.
Our system of delivery is built on years of operational experience and extensive knowledge. From process design and engineering to testing, installation, training and service. We have created a consistent feedback loop that delivers sustainable and state-of-the-art facilities and enables our customers to become the best operator.


Smart Solutions in 3D
During detailed engineering, the design of the facility is completed in a 3D-drawing. The 3D images allow customers to visualize the end product and help spark important conversations. Based on this 3D-model our engineers will create 2D-drawings which will be used for the fabrication and assembling. Our standard modular skids will be used where possible to make efficient delivery possible.
The use of standard modular skids reduces installation time and the margin of error.
“ What I really liked in working with WTT is the practical approach, the direct consultation structure and keeping the customer perspective in mind. And they do what they promise”

Our Technologies
We have the expertise to provide our customers with an array of waste treatment technology solutions to deliver the most optimal results, based on their unique needs. We’ve spent years strengthening our technologies so that they are as efficient and customizable as possible. All of our installations include one, or a combination of the following technologies:

Odour Abatement
Our engineers know how to meet the most stringent odour abatement criteria. We design each odour abatement system specifically to treat odourous compounds and ensure ideal dispersion to the atmosphere. Our facilities are designed to be air-tight and in a constant state of negative pressure. The aerobic systems within the design use the balance-of-plant air to process the organic steams, which allows for continuous air handling and superior process control. Based on local legislative requirements the system can be designed using chemical scrubbers, humidification, dust removal, heat exchangers, cooling towers, booster fans and bio-filters — all to ensure we are being a responsible neighbour. We also believe in building facilities close to generators to reduce the overall carbon footprint.
Composting & Biodrying
Our biological in-vessel tunnel technologies are individually controlled, and use forced aeration to process organic waste into compost. Our fully automated process allows the operator to set process parameters with the adaptability for different waste streams and seasonal fluctuations. Our modular construction and versatile control software allow the facility to treat organic waste optimally in less time. This process decreases costs and increases throughput — maximizing processing efficiency while keeping environmental conditions under strict control.


Heat Harvest
With the increasing importance of renewable energy and rising interest in by-product heat utilization, Waste Treatment Technologies (WTT) has developed a technology to be able to maximize the useful thermal energy production. Massive amounts of thermal energy are generated by the composting metabolic processes, which form a huge untapped resource for bio-energy. This heat can either be used for on-site purposes and save a lot of energy by heating buildings, pre-heat process air or dry other types of products, but it can also be sold as a source of renewable energy for neighboring operations like greenhouses, factories, heating networks or other demands for hot water. Valorization of waste heat plays a valuable role in offsetting dependence on fossil fuels, reducing operating expenses and increasing productivity.
Anaerobic Digestion
Anaerobic Digestion (AD) is an ideal circular solution. AD creates biogas from organic waste streams. Using a Combined Heat and Power unit (CHP) the biogas can be converted into renewable heat and power. Alternatively, by implementing and using a biogas upgrading system, the biogas can be turned into biomethane capable of fueling vehicles or injecting into the Natural Gas grid to render Renewable Natural Gas (RNG). We design and build AD systems based on our customers requirements, analyzing the waste streams to provide the optimal solution using wet AD, dry AD or a combination of both. Our dry AD batch system processes waste in-vessel without oxygen to produce biogas, while wet AD systems use digester tanks full of bacteria to break down the organic waste producing methane. Our experience in organic waste sector allows us the flexibility to create the ideal process to capture the most benefit from the feedstock.


Mechanical Treatment
We specialize in the design and construction of integrated and sustainable solutions. This system uses a combination of mechanical sorting and biological treatment like composting or anaerobic digestion. Mechanical treatment sets the stage for ideal aerobic and anaerobic biological processes. Once the materials have finished their time in-vessel, they travel to the final stage of handling –a screening system that ensures ideal product quality.
