LLRW is an acronym for waste defined as Low Level Radioactive Waste. The definition of LLRW can be described as all wastes arising and generated within the area of a nuclear power plant.
Such waste is not allowed to be removed from the nuclear power plant or treatment facility. The thermal treatment of the waste in the ENVIKRAFT A/S incinerator system secures that all nuclides are kept in a certain period in a controlled area in the incinerator and not released from the system until a volume reduction down to app. 1 - 4% of the original volume is achieved.

The waste is a combination of liquid waste, spent- and waste oil and solid waste, and can be described as:
- Liquid waste
Contaminated water, chemicals, solvents, etc.
- Partly liquid waste
Spent oil, waste oil, resins
- Solid waste
Wood, cardboard, textiles, rubber etc.
All waste from a nuclear power plant or treatment facility is regarded contaminated waste - i.e. containing gamma, beta, radio-nuclides, and the incinerator system is designed and build for securing the complete burn-out under controlled process conditions, making it possible to maintain a decontamination factor of 10-7 or better.
The ENVIKRAFT specially designed LLRW process control and flue gas treatment system efficiency is entirely unique and cannot be found elsewhere.
The de-ashing system operates continuously during operation in order to avoid any human contact, and the ash is discharged directly via a specially designed de-ashing sluice into a special container for final processing in lead or concrete drums.
