TYRES, asbestos and construction rubble are among the most fly-tipped types of trash, according to the latest Northern Ireland Environment Agency (NIEA) statistics.
Items from house clearances such as white goods and furniture were also among the most illegally dumped items.
Of the 155 incidents last year of tyres being dumped illegally reported to NIEA, 30 per cent were left at roadsides, 23 per cent on farmland, 14 per cent at bonfires and 12 per cent at commercial premises.
Mark Cherry, from NIEA's enforcement branch, said: "We are keen to remind all businesses, no matter how big or small, of their legal duty to dispose of their waste properly.
"It's their rubbish and their responsibility. Even if a business pays for someone to dispose of their waste they must ensure that it is stored, treated, transported and dealt with safely and properly.
"Some commercial operators want to avoid disposal costs and so dump the material. Our advice is to always use a licensed waste carrier or use an authorised waste management facility."
