Breaking down the biomass balance approach
What is biomass balance?
The biomass balance approach is a method used to balance the use of fossil and renewable resources by substituting a portion of fossil-based inputs with sustainably sourced biomass materials, such as biofuels or organic waste.
Why is it sustainable?
By incorporating renewable feedstocks, products and processes can achieve a reduced environmental impact, decrease reliance on non-renewable resources, and contribute to a more sustainable and circular economy.
How is biomass measured?
The biomass balance approach allows for the quantification and verification of the renewable content used, often through certified systems, ensuring transparency and credibility in the claims made about the sustainability of the final products.
What are some common feedstocks used today?
- Agriculture residues - This includes crop residues left after harvesting, such as corn stover, wheat straw, and rice husks.
- Algae and microalgae - Typically cultivated for their high lipid content, which can be converted into biomass materials.
- Aquatic plants - Some aquatic plants, such as water hyacinth, can be harvested and used for biomass applications.
- Crop waste - It's common to use waste from crop processing, like sugarcane bagasse or corn cobs.
- Energy crops - This can be switchgrass, miscanthus, and hybrid poplar, as well as giant reed, willow, and sweet sorghum.
- Forest residue - This can be leftover woody materials from forestry operations, like branches, tops, and logging residues.
- Municipal waste - This includes organic components of solid food waste and yard trimmings.
- Oilseed crops - This includes soybeans, rapeseed, and palm trees produce oils that can be converted.
What is the biomass balance production process?
- Select the renewables to be added at the start of the production chain
- Mix the alternative raw materials with the conventional materials
- Allocate the new mixture created to be used in products
- Certify the biomass balance products to be promoted and used
