WTZ e.V. focuses on addressing scientific-technical topics of innovative nature within the following three areas: Climate-friendly energy systems, establishment of circular economy value chains, risk areas and avoidance of climate-damaging emissions.

In the area of climate-friendly energy systems, WTZ e.V. aims, for example, to contribute to the circular economy design of biogas and biomethane production. Open scientific-technical questions of the hydrogen economy in the national and international context are also of special importance in this topic area.

In the area of building circular economy value chains, WTZ e.V. takes up the opportunities of the circular economy with the longest possible use of products and raw materials, not only to relieve the environment and nature, but also to contribute to the achievement of national climate goals. For example, technological challenges and opportunities of the CO2 value chain are comprehensively considered or niche topics such as protein production from methane are elaborated.

The evaluation of risk areas as well as the avoidance of climate-damaging emissions, which represent the third field of activity of WTZ e.V., include, for example, the examination of gas hydrates in permafrost regions or the technical possibilities for the reduction of methane emissions.
