Thailand produces large volumes of agricultural residues that remain underutilized:
35–40 million tons of rice straw annually
≈9–10 million tons cassava pulp per year
At the same time, industrial sectors rely heavily on fossil natural gas for process heat.
This creates a structural gap:
• biomass resources are abundant but unused
• industrial demand for energy remains fossil-based
• decarbonization pathways are limited

Thailand is one of Southeast Asia’s major agricultural economies and a significant producer of rice and other biomass resources. Large volumes of agricultural residues are generated every year across the country’s farming landscapes.
At the same time, Thailand has been actively promoting renewable energy, circular economy policies and sustainable agricultural development. These conditions create a strong foundation for exploring circular biomass platforms that connect agricultural resources with renewable energy systems and bio-based industries.
The bioREaaS initiative explores how Thailand can serve as a regional demonstration environment for circular bioeconomy systems based on agricultural biomass.
Thailand is among the world’s major rice-producing countries, generating substantial quantities of rice straw every year as a by-product of rice farming.
In addition to rice straw, Thailand also produces a variety of other agricultural residues including cassava processing residues, sugarcane residues and livestock manure. These biomass streams provide diverse feedstocks that can support renewable energy production and bio-based industrial processes.
The availability of these agricultural residues creates an opportunity to develop circular biomass supply chains that transform underutilised biomass into valuable resources.
Thailand’s agricultural landscape is characterised by extensive rice farming regions supported by irrigation systems and rural infrastructure. These landscapes provide suitable conditions for establishing regional biomass collection networks and decentralised biomass processing hubs.
By connecting farmers, biomass logistics systems and processing infrastructure, agricultural residues can be integrated into circular biomass and bioenergy economy.
Thailand has been expanding its renewable energy sector, including solar energy, biomass power and biogas systems. These developments provide a foundation for further exploration of renewable gas systems such as biomethane production from agricultural biomass.
Renewable gas infrastructure can complement existing renewable energy systems while supporting the transition toward low-carbon energy solutions.
Thailand’s geographic location and industrial capabilities position the country as an important gateway to Southeast Asia. The region contains some of the largest agricultural biomass resources in the world.
Developing circular biomass platforms in Thailand may help demonstrate how agricultural residues can support renewable energy systems and bio-based industries across broader regional supply chains.
The development of circular biomass to bioenergy platforms requires collaboration across agriculture, renewable energy systems and industrial processing technologies.
Thailand’s openness to international partnerships creates opportunities for cooperation with global technology providers, research institutions and circular bioeconomy initiatives.
Through such collaboration, agricultural residues can be transformed into renewable energy carriers and bio-based materials within emerging circular bioeconomy systems.
Target sectors include:
• cassava starch processing
• food and agro-processing
• animal feed production
• chemicals and materials
• export manufacturing
Key drivers:
• carbon pricing (emerging)
• Scope 3 emission requirements
• CBAM exposure
Biomethane provides a direct, immediate solution for industrial decarbonization.

Rice straw is one of the most abundant agricultural residues in the world. Across Asia, hundreds of millions of tons of rice straw are produced every year as a by-product of rice farming.
Despite this large biomass resource, rice straw is often underutilised or burned in agricultural fields. This represents both an environmental challenge and an untapped opportunity for circular bioeconomy systems.
The bioREaaS initiative explores how rice straw can become a valuable feedstock for renewable energy, biochemical production and advanced bio-based materials.
Rice straw contains several components with industrial value, including:
These characteristics make rice straw a promising feedstock for integrated biomass utilization pathways.
bioREaaS is designed as a modular circular bioeconomy platform consisting of four integrated components:
Rice straw is produced in large quantities across Southeast Asia. While traditionally considered a low-value residue, rice straw contains valuable industrial components including cellulose, lignin and silica.
These components can be processed into a wide range of energy and material products.
Agricultural residues can be converted into renewable biomethane through anaerobic digestion.
Rice straw can be combined with complementary substrates such as:
cassava processing residues
livestock manure
agricultural organic wastes
Biomethane produced through this process can supply renewable gas systems for transport, industry and energy infrastructure.
Digestate generated from biomethane production can be returned to agricultural soils as organic fertiliser, helping improve soil fertility and nutrient cycling.
This circular approach supports both renewable energy production and soil regeneration.
Rice straw contains biochemical compounds such as phenolics, fibres and other organic molecules that can be extracted through biorefinery processes.
These compounds can be used in food, feed and industrial applications.
Through thermal processing such as pyrolysis and activation, rice straw can be converted into carbon-based materials including activated carbon used in filtration, environmental treatment and industrial processes.
Rice straw naturally contains silica which can be recovered from biomass ash.
Purified silica can be used in industrial applications such as:
rubber additives
battery materials
specialty materials for advanced manufacturing
Rice straw can be converted into renewable gas through anaerobic digestion systems when combined with complementary organic substrates such as cassava processing residues or livestock manure.
Upgraded biomethane can be used for:
• renewable transport fuels
• industrial energy supply
• gas grid integration
Renewable gas systems can play an important role in the transition toward low-carbon energy infrastructure.
Rice straw contains cellulose and hemicellulose that can be processed through biorefinery technologies to produce biochemical compounds.
Potential products include:
• bio-based industrial ingredients
• natural polymers
• fermentation feedstocks
Such materials can support the development of sustainable chemical and bio-based product industries.
Through thermal processing such as pyrolysis and activation, rice straw can be converted into carbon-based materials.
Examples include:
• activated carbon for filtration systems
• carbon materials for environmental applications
• advanced carbon materials for industrial processes
These materials are widely used in water treatment, air purification and industrial filtration systems.
Rice straw naturally contains silica that can be recovered through controlled thermal and chemical processing.
Purified silica derived from rice straw can be used in:
• rubber and tyre industries
• specialty materials manufacturing
• advanced industrial applications
Rice straw therefore represents a potential source of bio-based silica materials.
The combination of renewable energy production, biochemical extraction and materials processing enables cascading biomass utilisation.
In such systems, agricultural residues are used across multiple value streams, maximising resource efficiency and supporting circular bioeconomy development.
The initial development phase focuses on establishing regional biomass hubs that collect and process agricultural residues such as rice straw.
These hubs function as local infrastructure nodes connecting farmers, biomass logistics and renewable energy production systems.
Each hub may process approximately:
100,000 – 300,000 tons of biomass per year.
As multiple biomass hubs are established within agricultural regions, they can form interconnected regional biomass networks.
These networks enable coordinated biomass supply chains, shared processing infrastructure and integrated renewable energy systems.
Such regional systems improve biomass logistics efficiency and strengthen rural circular bioeconomy ecosystems.
Over time, regional biomass platforms may evolve into industrial bioeconomy clusters that integrate:
renewable biomethane production
These clusters can process more than:
1 million tons of biomass annually.
Such industrial systems demonstrate how agricultural residues can support emerging circular bioeconomy industries while strengthening rural economies.
Rice farming landscapes across Southeast Asia produce large quantities of agricultural residues every year. When these residues are burned in fields, they contribute to air pollution, greenhouse gas emissions and the loss of valuable biological resources.
The bioREaaS initiative explores how circular biomass platforms can transform agricultural residues into renewable energy and bio-based materials while supporting environmental regeneration and sustainable agricultural systems.
Open burning of rice straw remains a major environmental challenge in many rice-producing regions. Converting rice straw into renewable energy and industrial materials can significantly reduce the need for agricultural residue burning, helping improve air quality and reduce particulate emissions.
By establishing regional biomass collection systems, agricultural residues can be redirected from waste streams into productive circular bioeconomy pathways.
Through anaerobic digestion and biomethane upgrading, agricultural biomass can be transformed into renewable gas suitable for transport, industrial energy systems and energy infrastructure.
Renewable biomethane can help reduce reliance on fossil fuels while supporting the development of low-carbon energy systems.
The bioREaaS platform is designed around the concept of cascading biomass utilisation, where agricultural residues are used across multiple value streams including renewable energy, biochemical extraction and advanced materials production.
This integrated approach maximises resource efficiency while reducing biomass waste.
Digestate produced from biomethane systems can be returned to agricultural soils as organic fertiliser, improving soil fertility and nutrient cycling.
This supports the transition toward regenerative agricultural practices and strengthens long-term soil productivity.
By integrating renewable energy production, circular materials processing and sustainable agricultural practices, the bioREaaS platform contributes to broader climate and circular economy objectives.
Such systems demonstrate how agricultural landscapes can become part of future renewable energy and bio-based industrial systems.
The development of circular biomass platforms requires collaboration across multiple technology areas including renewable gas systems, biomass biorefinery technologies and advanced materials processing.
International cooperation with European innovation ecosystems, including technology partners, may support feasibility development and technology exchange.
Potential areas of collaboration include:
biomethane and renewable gas systems
biomass multi-fuels boiler & steam generation systems
The initiative currently explores feasibility development for regional biomass platforms that integrate renewable gas production, biomass power, circular materials processing and agricultural biomass supply chains.
Guidance from organisations such as the Netherlands Enterprise Agency and IFU may help identify relevant programmes supporting feasibility development and collaboration with the innovation partners.
As the platform scales, it may also enable additional value pathways based on agricultural biomass, including biorefinery applications and advanced bio-based materials.
These pathways are considered long-term extensions of the platform and will be evaluated through future feasibility studies, depending on feedstock availability, market conditions, and suitable technology partners.
The platform remains open to collaboration with international technology providers in areas aligned with these future opportunities.
