Plagazi AB

Plagazi designs and develops projects that convert unrecyclable waste into sustainable, circular hydrogen. The company manages the entire process chain, from waste feedstock handling to hydrogen purification and utilization, by combining proven technologies into a complete, scalable solution.

Plagazi acts as a project integrator and co-developer, sometimes in partnership with local municipalities or industrial actors. Licensing or operational roles may vary by project.

The core plasma gasification reactor is provided by Plagazi’s strategic technology partner, InEnTec Inc., a leading provider of plasma gasification systems. Plagazi does not manufacture gasifiers itself but integrates InEnTec’s technology into a complete waste-to-hydrogen plant.

Plagazi provides full value chain integration, permitting support, funding alignment, and end-to-end project structuring. Our key strengths include:Easier Market Entry: We remove key barriers so partners can enter the waste-to-hydrogen market with confidence.Trusted Project Partner: Beyond technology, we deliver full-scale, scalable hydrogen project development.Regulatory & Permitting Expertise: We simplify approvals by navigating complex regulatory and permitting processes.Proven Technology Partnership: Our long collaboration with InEnTec strengthens gasification expertise and integration capabilities.Public Funding & Policy Alignment: We help secure grants, subsidies, and supportive EU funding.High-Impact, Sustainable Model: We deliver measurable environmental and social value through decarbonization and waste reduction.

Plagazi’s process, designed with our partner InEnTec Inc., is a three-step system that converts non-recyclable waste into clean syngas, the basis for producing circular hydrogen. The stages are:Down-draft gasification (Step 1): Waste is broken down in a high-temperature gasifier using oxygen and steam, producing an initial syngas.Plasma Treatment (Step 2): Remaining materials are exposed to plasma temperatures above 3,000°C. This melts inorganics into an inert slag and improves the quality and volume of the syngas.Refinement (Step 3): The syngas is polished in a thermal chamber to remove impurities, resulting in a clean, high-energy gas ready for hydrogen extraction.By combining these steps, Plagazi achieves highly efficient waste conversion, reduces harmful residues, and produces clean hydrogen with strong environmental benefits.

Plagazi’s process can treat a wide range of waste, with a focus on non-recyclable and hazardous fractions, such as residual municipal solid waste (RDF/SRF), industrial waste, and auto-shredder residues (ASR). The system is flexible and adapts to varying waste compositions, complementing existing recycling practices.In our flagship project, Gävle Circular Park, the feedstock is non-recyclable plastic waste. Instead of being landfilled or incinerated, this material is converted into circular hydrogen, cutting emissions, avoiding competition with mechanical recycling, and supporting EU sustainability targets. In short, Plagazi transforms problematic waste streams into valuable resources.

To ensure a consistent and specification-compliant supply of feedstock, Plagazi works with third-party leading waste management and trading companies. Through long-term contracts, these companies will provide non-recyclable plastic waste, amongst others, that meets the technical requirements of our process.This approach guarantees both volume stability and quality control, while also allowing to focus on waste streams that have no viable recycling alternatives, further strengthening the project’s environmental contribution.

Yes. Plasma technology has a long track record in industrial applications such as the steel sector. Our technology partner has demonstrated the safety and operability of this specific plasma gasification system at commercial scale.Plagazi builds on this foundation by integrating two proven steps: converting waste into syngas (with InEnTec’s technology) and producing hydrogen from syngas with established carbon capture and storage (CCS) methods. This ensures a safe, reliable, and scalable process.

A single reactor can process up to 36,000 tonnes of waste per year, equivalent to the residual waste from a mid-sized European city.Availability is designed at around 90%, consistent with industrial thermal processes and ensuring reliable, continuous operation.

Plagazi’s process is highly energy-efficient, consuming less than 10 kWh per kg of hydrogen (or less than 12 kWh/kg H₂ if oxygen is produced on-site). By comparison, electrolysis typically requires around 50 kWh/kg H₂.This means our process uses only a fraction of the electricity of electrolysis, lowering costs and enabling large-scale deployment. The exact energy demand depends on feedstock composition and output volume.

The solution is highly scalable. Capacity can be increased step by step by replicating proven reactor units and integrating them with centralized gas cleaning and hydrogen separation. This modular approach allows projects to start small and expand as demand grows, while keeping both CAPEX and OPEX flexible.

Plagazi produces high-purity hydrogen through advanced gas cleaning and separation technologies. Two key stages ensure that the final product meets strict industrial and mobility standards:Syngas purification: After gasification, the raw syngas is thoroughly cleaned to remove chlorinated compounds, sulphur species, heavy metals, tars, and particulates. This results in a clean, high-quality syngas, ready for hydrogen conversion.Pressure Swing Adsorption (PSA): Following the shift reaction, the gas stream is refined in a PSA unit that selectively adsorbs impurities and isolates hydrogen at very high purity levels, reaching >99.97% purity.The resulting hydrogen complies with ISO 14687-2 standards for fuel-cell grade hydrogen, making it suitable for demanding applications in mobility, industry, and refining.
