SimGas Netherlands

SimGas also has an office in The Netherlands, SimGas BV. This is the global head quarter of SimGas. This office has invested together with Silafrica Tanzania Ltd. to form the Joint Venture in SimGas East Africa. SimGas BV is responsible for partnering in new regions outside East Africa, finding new project partners for SimGas East Africa, Carbon Emission Rights, Product Development, and Research.

SimGas BV in the Netherlands was founded by two brothers: Sanne and Mirik Castro. Their goal is to prove that social entrepreneurship is profitable. SimGas BV engages in product development and investment in the distribution of decentralised utility systems. 

SimGas BV has developed two improved biogas systems for the Eastern and Southern African markets. These small-scale systems convert manure and organic household waste into methane gas, which can be used for cooking and lighting. These products have been developed in close collaboration with local partners and are mass produced and sold through our Joint Venture with leading East African plastics producer, Silafrica Tanzania Ltd.
