We are the leading specialists for the pretreatment and wet digestion of waste containing contaminants.

Our wet mechanical pretreatment impresses with highest substrate flexibility and efficiency in the separation of impurities. This ensures high operational reliability, minimises disposal costs, maximises profitability and secures best digestate quality.

Whether it is a mechanical-biological waste treatment plant (MBT) for processing residual or municipal waste, wet digestion plants for biowaste, food waste or commercial waste, plants for co-digestion with agricultural substrates or sewage sludge, upstream plants before composting, or upgrades or refurbishments of existing wet-mechanical treatment and/or fermentation plants, we offer engineering services based on 35 years of experience, proven and patented wet-mechanical pretreatment systems and turnkey digestion plants.
