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.
