Comprehensive Analysis & Visualization Platform
This platform provides comprehensive analysis of California's biomass resources across six major sectors: municipal waste, agriculture, food processing, forest biomass, animal agriculture, and crop culls. Together, these resources represent 79.2 million dry tonnes per year of potential feedstock for renewable energy, biofuels, biochemicals, and other sustainable products.
28.7M tonnes/year of organic waste from households, businesses, and institutions. Currently the largest biomass sector in California, offering significant diversion opportunities from landfills.
23.4M tonnes/year of dry plant stalks, leaves, and prunings left after harvest. Low moisture content makes these ideal for combustion and solid fuel production.
17.6M tonnes/year from 712 commercial facilities including canneries, dairies, wineries, and mills. Concentrated at facilities with existing infrastructure for easier collection.
3.7M tonnes/year from logging residues, small-diameter trees, and forest processing waste. Includes material from sustainable forest management operations.
3.1M tonnes/year (dry basis) from manure and bedding. Very high moisture content makes this ideal for anaerobic digestion and biogas production.
2.6M tonnes/year of rejected produce unsuitable for sale. High moisture and perishability make these best suited for composting or wet processing.
This Sankey diagram visualizes how California's 79.2 million tonnes of annual biomass resources can be allocated across six major end-use applications. The flow width is proportional to biomass volume. Hover over sectors and flows to see detailed information including feedstock characteristics and conversion pathways.
Direct combustion in power plants and combined heat & power systems. Produces approximately 103 million MWh annually.
Anaerobic digestion produces renewable natural gas for transportation fuel and grid injection. Ideal for wet feedstocks like manure and food waste.
Ethanol and biodiesel production from cellulosic and lipid-rich feedstocks. Potential for 3.9 billion gallons ethanol and 2.7 billion gallons biodiesel.
Densified biomass for heating and industrial applications. High energy density enables efficient transport and storage.
Pyrolysis creates stable carbon for soil enhancement and carbon sequestration. Improves soil health while storing carbon long-term.
High-value bio-based products including bioplastics (PLA, PHA), platform chemicals (succinic acid, lactic acid), solvents, adhesives, and composite materials.

Commercial food and agricultural processing facilities including canneries, dairies, wineries, breweries, and grain mills that generate organic waste streams.
Small-scale power generation systems that convert biomass to electricity at or near the point of use, improving efficiency and reducing transmission losses.
CHP facilities that simultaneously produce electricity and useful thermal energy from biomass, achieving efficiency rates of 60-80%.
Large-scale facilities that combust municipal solid waste to generate electricity, providing both waste management and renewable energy.

Purpose: Maps existing infrastructure for biomass collection and conversion
Biomass feedstocks are grouped into six distinct categories based on their physical characteristics, collection logistics, and optimal conversion pathways. This classification enables realistic resource planning and technology matching.
Why Separate: Dry plant material (10-20% moisture) left in fields after harvest
Collection Challenge: Geographically dispersed across agricultural lands; requires specialized equipment
Best Use: Direct combustion, pelletization, cellulosic ethanol - anything requiring dry feedstock
Examples: Almond hulls and shells, grape pomace, rice straw, corn stover
Why Separate: Rejected fresh produce with 80-90% moisture content
Collection Challenge: Highly perishable, must be processed quickly; seasonal availability
Best Use: Anaerobic digestion, composting, animal feed - wet processing only
Key Difference from Ag Residues: Too wet for combustion; different handling requirements
Why Separate: Concentrated at 712 commercial facilities with existing infrastructure
Collection Advantage: Point-source generation makes collection far easier than field residues
Best Use: Anaerobic digestion, industrial composting, biogas production
Key Difference: Includes high moisture solids (HMS), low moisture solids (LMS), and processing municipal solid waste (MSW) with varying moisture levels and processing requirements
Why Separate: Largest single sector; already has established collection infrastructure
Regulatory Context: Subject to AB 1826 and SB 1383 mandating organic waste diversion from landfills
Best Use: Anaerobic digestion, composting, waste-to-energy
Key Difference: Mixed feedstock requiring sorting; existing curbside collection systems
Why Separate: Woody material with unique regulatory and sustainability considerations
Collection Challenge: Remote locations, steep terrain, fire hazard reduction requirements
Best Use: Direct combustion, wood pellets, pyrolysis, biochar
Regulatory Note: Must comply with sustainable forestry practices; often tied to fire prevention
Why Separate: Very high moisture (85-95% wet basis); methane emissions if not managed
Collection Context: Concentrated at dairy and livestock operations (confined animal facilities)
Best Use: Anaerobic digestion is essentially the only viable pathway
Environmental Benefit: Captures methane that would otherwise be emitted; renewable natural gas production
Conversion factors and allocations are based on industry data, peer-reviewed research, and current technology capabilities. These represent potential outcomes under optimized conditions.
