Schirm GmbH

Schirm GmbH in Wolfenbüttel, DE manufactures various chemical products for industrial purposes. Previously, the accumulated production water could not be diverted directly. Therefore, Schirm GmbH used a different procedure – external incineration of their wastewater. Schirm GmbH was looking for an environmentally friendly solution. In 2011, Schirm GmbH and Envotherm came in contact to conduct preliminary investigations. Envotherm’s evaporation technology allows the process water to be purified or recycled. Envotherm analyzed the wastewater to ensure that the plant was suitable for Schirm GmbH.


Schirm GmbH is a leading production service provider for the chemical industry. Numerous multinational customers in agrochemical, fine and specialty chemical segments provide services in synthesis, formulation and packaging.

Schirm GmbH operates neutrally, flexibly, reliably, competently and worldwide. Various value-added services, such as formulation development, upscaling of synthetic routes, customs clearance, support with regulatory processes such as REACH or mediation of warehouse and transport logistics solutions complete the portfolio.


In 2015, Schirm GmbH decided to proceed with the lease of an Envotherm evaporation plant. The lease period was three years. Envotherm is responsible for monitoring the system, 70% of the system's service is digitized. This means for Schirm GmbH that the price per cubic meters in the three-year period, can be budgeted and planned. Schirm GmbH has decided to extend the lease for another three years.


The controller in the Envotherm evaporator is equipped with sensors that generate an alarm in time before the system needs to be cleaned or replaced with a consumable. The control system in the system is programmed in such a way that the screen operators can track the process and all system parameters on the touch panel, mobile phone or computer. Envotherm's engineer can connect to the plant and track the process online. The alarm informs the customer and Envotherm accurately, so fast problem solving is guaranteed.

Our accumulated production water has a varying composition, so other solutions have not worked optimally. We are pleased with the rental solution and service from Envotherm.
We recommend this solution to other industrial wastewater companies.
