Alternate Fuel and Raw Materials (AFR) Market For New Energy Generation Industry Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Insights and Trends of Alternate Fuel and Raw Materials (AFR) Market For New Energy Generation Industry

Carbon Pricing and Industrial Decarbonization

The alternate fuel and raw materials market gains support from the cost of carbon-intensive fuel use in cement and other heavy industries. Carbon pricing and related import requirements have increased attention to the emissions cost of cement, steel, and aluminum production. The Global Cement and Concrete Association reported that waste supplied less than 10% of cement kiln energy worldwide in 2025, leaving room for broader substitution where operational conditions allow ^{[1]Source: Global Cement and Concrete Association, “Cement and Concrete Industry Net Zero Action and Progress Report,” Global Cement and Concrete Association, gccassociation.org}. A peer-reviewed 2026 review found that RDF substitution can reduce the global warming potential of clinker production, with the outcome depending on the substitution rate and avoided landfill effects. The planned phase-out of free emissions allowances for cement increases the operating relevance of reduced fossil fuel use. This setting supports longer fuel supply agreements for certified recovered fuels, especially where buyers must document emissions reductions across their operations.

Landfill Diversion and Circular-Economy Mandates

Landfill diversion requirements support the alternate fuel and raw materials market by directing residual waste away from disposal. The revised EU Waste Framework Directive strengthened requirements related to separate collection and food waste reduction in 2025. EU waste policy links higher recycling expectations with lower landfill use by 2035. Material that remains after appropriate sorting can become feedstock for RDF and SRF processing, although processors must maintain quality controls before the material reaches industrial users. The Clean Industrial Deal presented in February 2025 places industrial decarbonization and circularity within the EU competitiveness agenda. Better source separation can increase the supply of suitable residual material without requiring higher total waste volumes, while maintaining the priority given to recycling under waste policy.

Cement-Kiln Fuel Substitution Economics

Cement kilns provide a large and established outlet for recovered fuel in the alternate fuel and raw materials market, especially where coal replacement aligns with emissions and waste policy. The GCCA reported that some European cement plants exceeded 80% thermal substitution with alternative fuels, while global use remained below 10% of kiln energy in 2025. India operated at a 4-8% thermal substitution rate and China at 10-20%, leaving a substantial gap between current practice and higher-use markets with mature pre-processing and kiln acceptance systems. Fuel quality remains central because kilns require a stable calorific value and low chlorine content. Research published in 2026 identified fuel composition and process conditions as important determinants of RDF performance in thermal treatment systems. Cimento Itambé commissioned a kiln in Brazil in 2025 that was designed for 50% alternative fuel thermal substitution and reached 67% in trials.

Expansion of Waste Sorting and Pre-Processing Infrastructure

Sorting and pre-processing determine whether available waste can meet industrial fuel specifications, which directly affects the reliability of contracted deliveries. Continuous measurement of moisture and calorific value can improve consistency compared with periodic manual sampling. Indonesia attracted public and private investment in waste-to-energy projects during 2026, including the Legok Nangka project in West Java. Indonesia's alternate fuel and raw materials market received support from public and private investment in waste-to-energy infrastructure during 2026. Italian guidance for larger SRF plants has supported in-line monitoring and stronger production controls, providing a reference for facilities that need to demonstrate consistent specifications to industrial buyers. Wider use of near-infrared sorting can reduce variation in recovered fuel quality and improve acceptance by industrial buyers.

Feedstock Quality Variability and Contamination

Feedstock variability remains a restraint on the alternate fuel and raw materials market because industrial users need predictable material properties. A 2026 study found that RDF quality results cannot be applied across feedstocks without testing each material composition. Chlorine is particularly important because higher concentrations can increase the risk of undesirable emissions during cement kiln co-processing. Storage also requires controls for fire prevention, moisture, and contamination. These requirements increase operating costs for smaller processors in the alternate fuel and raw materials market. Stronger chemical controls in Europe and the UK can further raise the specification burden for suppliers.

High Retrofit, Storage, and Permitting Costs

Existing cement and energy plants need burner modifications, handling systems, and safety measures before they can use larger volumes of alternative fuel. These capital needs are harder to fund where carbon pricing or blended finance is limited, which can slow investment by smaller plant operators. North American state-level approaches to waste diversion create uneven conditions for retrofit decisions. Large processing plants can face permitting periods of 3-5 years under industrial pollution control rules. Regulatory uncertainty in Southeast Asia and the Middle East and Africa can affect whether a processed material is treated as a product or as waste. Competition for premium residual streams and the falling availability of fly ash add further pressure to project economics.

Segment Analysis

By Fuel Type: Standardized SRF Supports Higher-Value Offtake

RDF held 34.8% of the alternate fuel and raw materials market share in 2025, supported by co-processing agreements with cement manufacturers in Germany, Italy, and Poland. SRF is forecast to grow at a 10.9% CAGR through 2031, the highest rate among fuel types. Its EN ISO 21644 biomass-content certification can support procurement decisions that require auditable renewable content. The alternate fuel and raw materials market rewards SRF suppliers that can provide stable specifications and traceable material, because industrial buyers need clear evidence of fuel composition and renewable content. Higher biogenic content can help cement producers separate renewable and fossil carbon in emissions reporting.

Within the alternate fuel and raw materials market, waste plastics provide high calorific value in co-firing blends, but recycling policy can restrict their use for energy recovery. Tire-derived fuel remains important in parts of South America. Brazil used tire-derived fuel in cement kilns under Ibama monitoring in 2024. Tire-derived fuel also remains relevant to the cement sector in Mexico. Process-derived fuels and agricultural residues retain smaller roles where segregated waste collection is less developed.

By Raw Material Type: Fly Ash Leads While Steel Slag Gains Importance

Fly Ash held 38.9% of the alternate fuel and raw materials market share in 2025 because it is a well-established supplementary cementitious material. Its supply is expected to tighten as coal generation declines. A 2025 scenario analysis projected that EU fly ash supply could fall from 8.5 million tonnes in 2025 to 1.9-2.7 million tonnes by 2035 ^{[2]Source: R. Snellings et al., “Concrete Change: Exploring Future Scenarios for the Supply of Supplementary Cementitious Materials in the EU,” Developments in the Built Environment, doi.org}. The alternate fuel and raw materials market can use legacy stockpiles while fresh ash production declines.

Steel Slag is forecast to grow at a 10.2% CAGR through 2031, making it the fastest-growing raw material type. Research published in Nature Communications found that a binder made from 70% washed steel slag and 30% fly ash delivered a 133.7% improvement in compressive strength and showed a potential global emissions reduction of 2.2-3.0 gigatonnes. Blast furnace slag and foundry sand remain relevant but can face supply changes as steel and foundry operations decarbonize. Other material types include municipal solid waste incineration bottom ash and calcined clay, which are being assessed as processors seek to reduce dependence on inputs affected by coal phase-outs. The alternate fuel and raw materials industry is therefore broadening its input base as traditional supplementary cementitious materials become less available, increasing the value of processing systems that can manage different mineral inputs.

By Application: WtE Plants Provide the Largest Outlet

Within the alternate fuel and raw materials market, WtE Power Plants represented 61.7% of the alternate fuel and raw materials market size for applications in 2025, reflecting the installed base in Europe and Northeast Asia. These plants can provide high-volume demand for standardized fuels and recovered materials, allowing processors to support predictable operating schedules and improve the use of residual waste. SUEZ secured a 10-year operating contract in March 2026 for the Valserhône energy-from-waste facility in France, beginning in September 2027. Long operating contracts can improve confidence for upstream sorting and processing investment. This application base provides an important route to market for material that cannot be recycled, provided that operators meet environmental controls and local permitting conditions.

Biomass and Bioenergy Plants are forecast to grow at a 10.5% CAGR through 2031. India expanded bioenergy and waste-to-energy capacity through 2025, supporting the use of biomass-origin recovered fuels. Indonesia announced several waste-to-energy projects in 2026 under Presidential Regulation No. 109 of 2025. Biomass applications also require sustainability certification and compliance with greenhouse gas saving requirements, creating a clear preference for suppliers that can document feedstock origin and handling conditions. Industrial co-firing in glass, chemicals, and ceramics remains a smaller outlet for high-calorific-value material.

Geography Analysis

The alternate fuel and raw materials market in Europe held 39.6% of the alternate fuel and raw materials market share in 2025, supported by mature sorting systems, landfill rules, and cement kiln co-processing capacity. Germany, Italy, Poland, France, and the United Kingdom accounted for much of the region's SRF and RDF demand. Poland and Germany have substantial SRF co-firing capacity as cement producers replace coal. Indaver opened the Rivenhall Integrated Waste Management Facility in Essex in June 2026, a GBP 589 million project that processes up to 595,000 tonnes of residual waste each year and produces 55 MW of electricity ^{[3]Source: Indaver, “Rivenhall Integrated Waste Management Facility Officially Opens,” Rivenhall IWMF, rivenhall-iwmf.co.uk}. EU waste and industrial policy continue to support demand for recovered fuels and materials in the region, while harmonized classifications and emissions thresholds influence how operators structure processing investments.

Asia-Pacific is forecast to grow at an 11.1% CAGR through 2031, the fastest geographic rate in the alternate fuel and raw materials market. India and China have lower cement kiln thermal substitution rates than leading European facilities. Indonesia, India, Vietnam, and Thailand are developing processing and waste-to-energy capacity. Indonesia launched more than USD 600 million in waste-to-energy investment during 2026. India has a substantial agricultural biomass resource that can support biomass-origin recovered fuels. Japan and South Korea, with 50-65% thermal substitution rates in cement kilns, provide regional reference points as policy frameworks develop and neighboring markets work to improve waste access and fuel preparation.

North America, South America, and the Middle East and Africa have different demand patterns. In North America, landfill gas conversion to renewable natural gas is an important energy-recovery route. Republic Services and Archaea Energy opened their first joint renewable natural gas facility in Fort Wayne, Indiana, in June 2026. South America continues to use tire-derived fuel within cement co-processing. South Africa, Morocco, and Saudi Arabia are emerging locations for specification-controlled alternative fuel activity.
