The Environment Agency is consulting on new rules for regulating small-scale clinical waste treatment.
These would allow operators to treat up to 100 tonnes of clinical and healthcare waste a year under a standard permit.
The consultation, which began on 17 January, covers hazardous and non-hazardous waste produced and treated at medical practices and certain waste handled by medical staff in the community.
The draft rules allow clinical waste to be treated by heat, chemicals and irradiation, but not burning. All treatment must take place within a building with an impermeable surface and a sealed drainage system.
