Where Waste
Becomes a Resource
Indeloop develops LOOPER, a modular thermochemical coversion system that converts selected waste types into syngas for energy or hydrogen production, with the potential for further valorisation of the solid residue.
Technology Development Focused on Real-World Application
Indeloop is a Croatian technology company developing LOOPER, a modular system that converts selected waste types into syngas for energy production or hydrogen extraction. We develop and validate the technology in collaboration with industrial partners, research institutions and end users.
Modular & Scalable Technology
LOOPER is developed as a modular technology adaptable to different waste types, capacities and end-user requirements.
Decarbonisation
We develop technology that reduces the need for disposal of difficult-to-recycle waste types by enabling their conversion into energy carriers and material products.
Waste as a Local Resource
A future in which waste is viewed not only as a disposal cost, but as a locally available resource for energy and useful materials.
Energy Resilience
Local energy production from locally available resources can contribute to a more resilient and secure energy supply.
Validation in Real-World Conditions
LOOPER is developed and tested through international and EU-supported projects across different waste types, capacities and operating environments.
Improved Resource Utilisation
Valorising both syngas and solid residue increases the utilisation of incoming material and reduces the amount of unused material.
From Waste to Energy, Hydrogen and Materials for Further Use
LOOPER integrates feedstock preparation, thermochemical conversion, and the downstream treatment of syngas and solid residue according to end-user requirements.
Modular Technology for Turning Waste Into Resources
LOOPER converts selected waste types into syngas and solid residue. Depending on the system configuration, syngas can be used to produce heat or electrical energy or further processed for hydrogen extraction.
Feedstock Flexibility
LOOPER is engineered and adapted to the properties of different carbon-containing waste types, subject to prior feedstock testing and process validation.
Modular Design
The system is configured according to the required capacity, site conditions and end-user requirements.
Syngas Valorisation
Syngas can be used to produce heat or electrical energy or further processed for hydrogen extraction.
Solid Residue Valorisation
The solid residue is analysed to determine opportunities for its safe and technically justified further use.
From Feedstock to Useful Products
Feedstock Preparation
Waste is received and prepared for thermochemical conversion in the LOOPER system.
Thermochemical Conversion
The prepared waste undergoes controlled thermochemical conversion, producing syngas and solid residue.
Gas Cleaning & Conditioning
The produced syngas is cleaned and conditioned according to the requirements of its intended downstream use.
Energy or Hydrogen
Depending on the system configuration, syngas can be used to produce thermal or electrical energy or further processed for hydrogen extraction.
Solid Residue Valorisation
The solid residue is analysed to determine opportunities for safe and technically justified further use, including potential applications in construction materials.
