Design + Build

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.

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.

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 (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.

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.
