The study was commissioned following the discovery of a massive illegal dump in Campsie on the outskirts of Londonderry.
An estimated 516,000 tonnes of rubbish was buried in an area close to the River Faughan on a site which stretches over a mile - everything from household to industrial waste.
It was just the tip of the iceberg, with the independent investigation team lead by the former Director of the Welsh Environment Agency Chris Mills discovering that gangs are dumping waste right across NI, making huge profits and damaging the environment.
Twenty other suspect operations have now been identified and probed, and persecutions are being pursued against 34 people.
Mr Mills has recommended an overhaul of the entire system to prevent criminal activity.
He said: "The cost of dealing with this historic legacy could run into hundreds of millions of pounds and failure to do so risks infraction under the EU Waste Framework Directive."
Based on an assumption the clearance work was required at 100 locations in the region, Mr Mills estimated the cost could reach as much as £250m.
He revealed that the regulation of waste here is highly vulnerable to criminal infiltration which can allow criminals to access vast profits with low deterrents.
Environment Minister Mark H Durkan said the report "makes for sober reading".
The SDLP man went on: "Mills is clear in pointing out that we have serious problems right across our waste systems.
"Mr Mills provides a set of recommended actions to fix these problems. Given the scale of the problems, the implementation of these actions must be done in a powerful way that creates and delivers fundamental change.
"I am determined that this will happen as quickly as possible so that we can start building a waste system that everyone in Northern Ireland can have confidence in."
Proposal on how to tighten up the law will go before the minister early in the New Year.
