Closing loops and consuming fewer natural resources, avoiding waste or – even better – using it to create new value and shaping the future with sustainable and efficient solutions. This is what drove us to establish OutNature.




The primary raw material used to make paper is pulp, which is mainly sourced as virgin fibers from industrial-scale forestation. Oftentimes, volatile markets also mean long transport routes and a high carbon footprint. Downstream, wood processing also requires large amounts of energy and chemicals. At the same time, demand is growing as more and more paper-based packaging is used as an alternative to plastics. This has already been implemented with success in the food industry.
But how can paper be manufactured more sustainably so that it offers a real alternative?

Our solution:

The versatile silphium plant, which can be used to manufacture paper and to produce biogas and biomethane for energy recovery.

Our raw materials
the silphium plant

Silphium (Silphium perfoliatum L.) is a plant species native to North America that is currently cultivated on roughly 10,500 hectares (2022) of land in Germany. It is perennial and used primarily for its properties as an energy crop. However, it also has a host of benefits during its life cycle.
