Walki®Biomass Cover
Protect Biomass. Increase Energy Value.
Fibre-based protection designed to elevate the energy value of forest residues.
Keeping biomass dry, valuable and ready for efficient bioenergy production.
Elevating the Energy Value of Forest Residues
Forest residues such as logging leftovers, thinnings and wood chips are valuable renewable energy resources. However, when stored outdoors they are exposed to rain, snow and ice, which can significantly increase moisture levels and reduce their calorific value.
Walki®Biomass Cover is a high-performance, fibre-based laminate designed to protect biomass piles during forest storage. By shielding the material from weather exposure, the cover helps maintain lower moisture levels, improving fuel quality and increasing the economic value of biomass.
Field measurements show that moisture levels can be reduced by up to 18%, enabling more efficient combustion and improved bioenergy performance.
For forestry operators, biomass suppliers and energy producers, protecting residues during storage can transform waste material into a more valuable energy resource.
Product Overview
Walki®Biomass Cover is a durable laminate structure made primarily from renewable fibre materials, reinforced for strength and designed for demanding forest conditions.
The cover is engineered to provide reliable weather protection while remaining practical for forestry operations.
Key features
- Reduces moisture in stored biomass by up to 18%
- Strong fibre-based laminate with reinforcement scrim
- Designed for forest storage conditions
- Easy to apply using standard forestry machinery
- Wide formats to cover large piles efficiently
- Can be chipped together with the biomass
- Optional printing for ownership or instructions
The solution provides a simple and cost-effective alternative to building dedicated storage infrastructure.
Designed for Efficient Forestry Operations
The cover integrates easily into standard forestry workflows.
Once biomass residues are stacked, the cover can be unrolled over the pile using a crane and reel bar system. Installation typically takes around 10 minutes per pile, allowing fast coverage without slowing down harvesting operations.
Because the laminate is tear-resistant and reinforced, it withstands demanding outdoor conditions while still allowing airflow around the pile when properly stored.
This practical design helps operators protect biomass without adding significant operational complexity.
Walki Offers Extensive Customisation
Every biomass storage operation is different. Walki®Biomass Cover can be adapted to meet operational requirements.
Customisation options
- Barrier level and coating type
- Width and reel length
- Reinforcement strength
- Surface printability
- Branding or ownership identification
- Handling and application features
This flexibility allows forestry companies and biomass operators to implement solutions tailored to their logistics and storage practices.
