The price incentive for households to cover the cost of waste collection and treatment is consequently low. There is clearly scope for price increases, considering in particular that the average level of the waste bill for households seems to be less than 1% of average income (GHK, 2006). The TGR is applied annually and differentiated depending on the type of treatment (waste deposited in landfills, managed by specific waste flow systems, or sent to the integrated centres for the recovery and disposal of hazardous waste, CIRVER, and incinerated or co-incinerated).
