Tree Shelters Made of Renewable Resources 

Development of innovative tree shelters and concepts to avoid plastic accumulation in forests 

Objective

The aim of the joint project is the strategic development of new, innovative, environmentally friendly tree shelters based on organic and residue-free degradable natural products and the removal of previously used, conventional tree shelters.

Tasks

  • Creation of trial areas in the forest
  • Compilation of a life cycle assessment and development of tree shelter software
  • Development of a concept for the removal of tree shelters
  • Development of new, innovative, environmentally friendly tree shelters based on the organic and residue-free degradable natural product SAVUTEC® (vulcanized fibre)
  • Assurance of complete rotting and avoidance of microplastics in the forest
  • Selection of suitable resources for SAVUTEC® tree shelters and development of suitable formulas on a laboratory scale.
  • Transfer to an industrial production capability
  • Production of tree shelter prototypes with selected tree shelter manufacturers
  • Analysis of degradability and functional testing of the manufactured prototype in field trials
  • Examination of the biological decomposition of tree shelters under aerobic conditions
  • Analysis of the lifespan and ecotoxicological impact of the tree shelters

Status Quo

  • Plastic products have come under public criticism as particles that are not easily biodegradable in the environment
  • Tree shelters are usually made of PE, PP, HDPE, PVC
  • Annual new tree shelters in the double-digit millions make them a relevant factor in forest management.

Advantages

  • The conversion of the forest into stable mixed stands, the use of rare tree species in the face of climate change and the inexpensive reforestation after climate-related storm events all lead to an expected major increase in the number of tree shelters that will be needed.
  • The strategic construction of stable, plastic-free, biodegradable tree shelters will lead to a consistent reduction in the use of tree shelters made of plastic, for example, PE, PP, HDPE or PVC, and counteract the accumulation of plastic in the forest.

Project Data and Partners

Growth covers usually consist of petrochemically produced plastics that are difficult to break down in nature.

In the case of bite-sensitive tree species, forest owners also rely on growth covers within stands.
