A Modular Waste-to-Resource System
LOOPER is a modular thermochemical system for converting selected waste streams into syngas. Depending on the system configuration, syngas can be used to produce heat or electrical energy or for hydrogen extraction, with the potential to valorise the solid residue into valuable resources.

Engineered for Real-World Deployment
Indeloop develops LOOPER, a modular thermochemical system for converting selected waste streams into syngas. The system is configured according to feedstock properties, required capacity, site conditions, and end-user requirements.
LOOPER is being developed to process different waste streams, including sewage sludge, RDF, biomass, textile waste, and non-recyclable plastics. The suitability of each waste type is determined through prior testing and process validation.
In addition to syngas, the process generates a solid residue that is analysed to determine opportunities for its safe and technically viable further use, including potential applications in construction materials
What Makes LOOPER Different
Five key features that enable LOOPER to adapt to different waste types, capacities, and deployment scenarios.
Feedstock Flexibility
LOOPER is designed and adapted to the properties of different carbon-containing waste streams, subject to prior waste testing and process validation.
Modular Design
The system is configured according to required capacity, site conditions, and end-user requirements.
Scalability
The modular design enables system capacity to be adapted to end-user requirements.
Flexible Outputs
Depending on the system configuration, syngas can be used to produce thermal or electrical energy or for hydrogen extraction.
Solid Residue Valorisation
The solid residue is analysed to determine opportunities for its safe and technically viable further use, including potential applications in construction materials.
Waste Types We Process
Applicable to different waste types subject to prior testing and process validation.
From Syngas to Energy, Hydrogen and Materials
LOOPER produces syngas and a solid residue. Depending on the system configuration and end-user requirements, these outputs can be further valorised through energy and material applications.
Hydrogen-Rich Syngas
The primary gaseous product of the LOOPER process which, depending on the system configuration, can be used to produce thermal and/or electrical energy or for hydrogen extraction.
Ash and Biochar
The solid residue is characterised to determine opportunities for its further use, including potential valorisation in construction materials.

| Feature | INDELOOP LOOPER | Typical Competitors |
|---|---|---|
| Technology Readiness | TRL 6+ for key system components | TRL 3–5 (testing stage) |
| Feedstock Versatility | Textile waste, RDF, non-recyclable plastics, sludge, biomass and biowaste | Often optimised for a narrower range of feedstocks |
| Product Valorisation | Valorisation of syngas and solid residue | Often primarily focused on syngas valorisation |
| System Flexibility | Thermal or electrical energy, with the possibility of hydrogen extraction | Limited to configurations producing a single form of energy |
| Solid Residue Applications | Research and demonstration of applications in construction materials through the AshCycle project | Solid residue valorisation is often not a primary focus |
| Modularity & Adaptability | System configuration based on feedstock, capacity, site conditions, and end-user requirements | Lower adaptability |
| CO₂ Emission Savings | Demonstrated reduction in CO₂ emissions | Not demonstrated |
