Panda Waste customers could be fined up to €25 for throwing away food in their black wheelie bins.
Around 150,000 households are being made aware of a range of changes to contracts.
The fine system for polluting any of its bins will be implemented from next week.
Earlier this year the company installed cameras on its trucks to catch households doing things like throwing away nappies in green bins or even disposing of dead pets.
Now it's stepping up its campaign by fining customers up to €25 euro for putting the wrong items into any of its black, green or brown bins. That includes food in black bins or cooking oil in brown bins.
New contracts also force customers to allow Panda employees to enter their property to inspect their rubbish.
There'll also be fines for missing direct debits, extra levies for any waste deemed hazardous and €30 at the end of a contract for cleaning your bin.
