biomassamäärä

Biomassamäärä, or biomass amount, is a term used to describe the total quantity of biomass available or used within a given context. In energy and material planning, it denotes the mass or energy content of organic matter that can be harvested, processed, or stored.

Biomass amount is commonly reported on a dry matter basis to enable comparison, but it can also be expressed as fresh weight, volume, or energy equivalents such as megawatt-hours or gigajoules. Measurement relies on forestry inventories, agricultural statistics, residue generation data, and remote sensing, often combined in regional or national biomass balance assessments.

Key factors influencing the biomass amount include moisture content, chemical composition, and the stage of processing. These factors affect energy density, transport requirements, and the feasibility of use in different supply chains.

Biomass sources encompass forests (roundwood, logging residues, bark), agricultural residues (straw, husks), energy crops, organic waste, and dedicated supply chains for bio-based materials. The biomass amount helps quantify potential supply, plan harvest or collection campaigns, and assess sustainability and life cycle impacts.

In policy and planning contexts, the biomass amount informs targets for renewable energy, carbon accounting, and security of supply. It is used to estimate potential energy production, determine sustainable harvest levels, and model logistics and market dynamics. Uncertainties arise from seasonal variation, market demand, policy changes, and data quality.

In Finnish usage, biomassamäärä often refers to the quantity of biomass that is available or mobilizable in a region or system, serving as a primary input for energy planning and environmental statistics.
