In a context marked by increasingly stringent environmental regulations and unpredictable energy price volatility, industrial waste management has evolved from a simple, costly operational constraint to a major strategic issue. For production sites, whether they operate in the agri-food, chemical, materials, paper, or plastics industries, the question is no longer just how to dispose of waste at the lowest cost, but how to transform this dual problem (waste/CO₂) into a real opportunity for decarbonization and margin security.
Mini Green Power, a mission-driven company, offers a concrete solution: converting waste into low-carbon local energy. This innovative approach is fully in line with the ambitious objectives of the European Green Deal (-55% GHG emissions by 2030) and meets the new requirements of CSRD extra-financial reporting.
Industrial sites are currently caught in a vice between multiple pressures:
You have to deal with tightening regulations on greenhouse gas (GHG) emissions and waste management (5R hierarchy: reduce, reuse, recycle, recover, bury). Since January 1, 2025, the AGEC law has required the sorting of nine separate waste streams (paper, cardboard, metal, plastic, glass, wood, textiles, plaster, mineral fractions, food waste) and extends extended producer responsibility (EPR) to professional packaging. At the same time, the CSRD directive requires a growing number of companies to publish a comprehensive carbon footprint, covering scopes 1, 2, and 3 of their emissions. CSRD reporting requires detailed data on the decarbonization trajectory.
Waste treatment costs (landfill or external incineration) continue to rise. At the same time, the volatility of gas, fuel oil, and electricity prices is weighing heavily on margins. In heat-intensive industries (paper, agri-food, chemicals, plastics), the production of process heat, steam, or drying, often provided by natural gas or fuel oil boilers, are major energy items and significant sources of direct CO₂ emissions (scope 1).
Scopes 1 (direct emissions) and 2 (purchased energy) are mandatory in regulatory GHG reports. Scope 3 (indirect emissions throughout the value chain) often accounts for more than 60% of total emissions. Intelligent waste management is becoming a major strategic lever for the overall carbon footprint.
Faced with these challenges, energy recovery makes it possible to transform the double cost line (“waste cost” and “energy cost”) into an industrial asset that is useful for your competitiveness.
Energy recovery from industrial waste is a circular economy strategy that involves transforming production residues, biomass waste, agricultural waste, or Solid Recovered Fuels (SRF) into energy that can be used on site: heat, steam, electricity, or cooling. This energy is produced by controlled combustion in dedicated facilities.
In concrete terms, recovery can involve:
• Agri-food production residues (agricultural waste, co-products, sludge, fibrous residues).
• Wood and biomass residues (B-grade wood, pruning waste, green waste).
• Solid recovered fuels (SRF) from non-recyclable sorting rejects.
• Other solid process residues with calorific value.
The main objective is to replace fossil fuels (natural gas, fuel oil, propane) with renewable, local, and less volatile energy sources.
Mini Green Power's “mini-green power plants ” approach
Where Mini Green Power stands out is in its approach to human-scale power plants. MGP installations are specifically designed for the needs of small to medium-sized industrial sites, covering power ranges from 1 MWth to 10 MWth, with the possibility of increasing to 20 MWth with multiple units.
This reduced scale changes three major things for your site:
Energy is produced directly on the industrial site, as close as possible to where it is needed (steam, drying, processes), which limits energy losses and increases autonomy. Waste is sourced locally (your own or from local deposits), reducing logistics costs and the carbon footprint of transport.
The power stations are modular, demountable and transportable, reducing risks for financiers and offering operational flexibility. Their footprint is moderate, between 300 m² and 2,000 m².
The technology is based on patented staged combustion (36 patents filed). The technology is based on patented staged combustion (36 patents filed). This process can handle a wide range of waste of varying quality and moisture content (from 10 to 55%) without complex pre-treatment. Three-stage combustion ensures complete combustion at high temperatures (1,000°C), minimising pollutant emissions while maximising energy efficiency (thermal efficiency greater than 80%). Dedicated dryers can be added to the system to recover the most humid deposits or to dry wet waste before disposal.
Investing in waste-to-energy with Mini Green Power generates concrete and quantifiable benefits:
Replacing fossil fuels with energy from biomass or RDF is the most direct lever for decarbonization.
By replacing natural gas (approximately 0.418 kg CO₂/kWh) or fuel oil (0.73 kg CO₂/kWh) with biomass (approximately 0.230 kg CO₂/kWh) or RDF, CO₂ emissions reductions become substantial. A few megawatts of thermal capacity can avoid the emission of several hundred or even thousands of tons of CO₂ per year. For example, a 1 MWth power plant operating 8,000 hours per year can avoid the emission of approximately 1,500 tons of CO₂ per year by substituting natural gas. These reductions can be directly valued in your regulatory GHG balance sheet and in your CSRD reports.
Mini Green Power Plant technology also enables the co-production of biochar alongside energy. Biochar is a plant-based charcoal produced by the pyrolysis of biomass, recognized as a means of carbon sequestration. When incorporated into soil, materials (concrete, cement), or used in certain agricultural applications, it acts as a long-term carbon sink, sequestering CO₂ in a sustainable manner.
This production of certified biochar can, subject to a robust methodology (quantification, traceability, certification), generate carbon credits or additional revenue. This reinforces the credibility of your net-zero trajectory by complementing your emissions reduction with sustainable CO₂ removal solutions.
Waste recovery provides crucial economic stability.
By producing your own energy from locally available waste, you reduce your dependence on fluctuations in international gas and electricity prices. The energy produced is stable, as the facilities can operate up to 8,000 hours per year, ensuring on-demand production, unlike intermittent sources.
Instead of paying for disposal (landfill or external incineration), you turn this cost into an energy resource. Fuel costs can even be low or negative for waste that was previously destined for landfill.
The CAPEX (initial investment) of a Mini Green Power facility is lower than that of traditional incinerators per thermal megawatt. With optimized operating costs (remote control, automation), MGP plants offer an competitive return on investment.
The recovery approach strengthens your strategic and regulatory positioning.
• Compliance with CSR and regulatory requirements: You meet the requirements of the AGEC law (waste sorting), the CSRD (detailed non-financial reporting), and the Green Deal (-55% GHG by 2030).
• Quantitative reporting: Your non-financial reporting is supported by concrete, quantified data: tons of waste recovered, tons of CO₂ avoided, and the share of renewable energy in your energy mix.
• Local value creation: The approach is part of the circular economy: local waste becomes a valuable resource in a short supply chain, contributing to the region's energy independence.
For any industrialist, the transition to energy recovery is a structured process, carried out in partnership with Mini Green Power.
This step consists of accurately mapping your waste sources: volumes, seasonality, composition, moisture content, and calorific value. This analysis is compared with your specific energy needs (process heat, steam, drying, heating). The objective is to identify a sufficient alignment between your waste (or local waste) and your energy needs to justify a Mini Centrale Verte®.
This crucial step allows for preliminary sizing of the plant (power, type of recovery boiler) and verification of regulatory compliance (ICPE, atmospheric emissions). A robust business case is built: calculation of CAPEX, OPEX, cost of energy produced, return on investment horizon, and simulation of emissions avoided compared to the fossil fuel reference scenario.
Mini Green Power defines a standard or modular solution, integrated with your existing utilities (steam network, hot water loops). An automated control system is put in place, allowing for fine-tuned management, continuous monitoring of emissions (NOx, CO, dust), and remote supervision.
Once the plant is operational, it is run and adjusted to optimize energy and environmental performance. Consolidated data is made available to you to facilitate:
• Your GHG balance sheet (mainly scopes 1 and 2).
• Your CSRD reporting on the decarbonization trajectory.
• The potential valuation of carbon credits linked to biochar.
The MGP solution is intended for all manufacturers that consume thermal energy and generate recoverable waste.
Scenario 1 – Agri-food site: organic residues and steam requirements
• Context: An agri-food site generates organic residues (co-products, sludge, fibrous residues) that are difficult and costly to dispose of, while having high steam requirements for cooking or sterilization.
• Solution: Installation of a Mini Centrale Verte® powered by these internal residues and local biomass, coupled with a dryer to ensure a homogeneous fuel.
• Results: Reduction in gas purchases for the steam boiler, CO₂ avoided by fossil fuel substitution, lower waste treatment costs, and a smaller carbon footprint for finished products. A 750 kWth to 2 MWth installation can provide the heat required for the processes.
Scenario 2 – Paper mill/materials: fibrous waste and process heat
• Context: These industries require large amounts of heat for drying and often generate fibrous waste.
• Solution: Recovery of fibrous waste or local biomass for process heat or steam.
• Results: A significant portion of heat requirements covered by low-carbon local energy, stable energy costs. For a paper mill, a 9 to 12 MWth plant can replace natural gas for dryer cylinders, reducing emissions by several thousand tons of CO₂ per year.
Scenario 3 – Chemical/plastics industry: RDF and biochar
• Context: Sites faced with unsorted waste, non-recyclable combustible waste (RDF), and strong regulatory pressure to reduce GHG emissions.
• Solution: Use of RDF and other local combustible waste in a Mini Centrale Verte® (Mini Green Power Plant) with fine control of emissions and biochar production.
• Results: Significant contribution to the reduction of scope 1 emissions, possibility of integrating certified biochar into a CO₂ removal credit strategy.
European Waste Reduction Week (EWWR), held every year at the end of November (November 22-30, 2025), is a key mobilization event that promotes the 5R rule (Refuse, Reduce, Reuse, Recycle, Return to the earth). EWWR reminds us of the need to better manage the waste that remains after prevention and recycling.
Energy recovery is part of this approach on two levels:
It gives a second life to waste that can no longer be avoided or recycled, thus avoiding landfill or incineration without recovery.
By producing energy directly from local waste, you reduce transportation, secure your energy supply, and limit the use of imported fossil fuels.
By acting now, manufacturers can not only anticipate future regulations and improve their CSR image, but also benefit from public aid, such as the ADEME Heat Fund, which supports renewable energy production facilities using biomass or SRF. SERD is an ideal opportunity to showcase these concrete industrial decarbonization projects.
Conclusion: your decarbonization journey starts with your waste
Energy recovery from industrial waste is no longer just an option. It is a strategic lever for:
• Reducing your GHG emissions (scopes 1, 2, and sometimes 3).
