Less than 30 million tonnes of waste a year in the UK is being dumped as landfill in the UK as an increasing number of sites close, according to market researchers.
A report by BDS Marketing Research said more than 20 landfill sites closed in the last year, meaning more than 150 sites have closed since 2008.
The report said due to a number of factors this was the first time that fewer than 30 million tonnes of waste had been sent to landfill.
BDS said: “The landfill tax has increased to £72 per tonne. Some landfill sites have completed their void and planning has not been allowed for an extension or the site has come to the end of its natural life.
“The development of alternative waste treatment options is also diverting waste streams away from landfill.”
FCC was estimated to be largest landfill company, as Viridor overtook Biffa into second place.
BDS said: “Together, these three companies are estimated to have around 40% of the market. Other companies comprising the top five are Veolia and SITA.”
The report estimated the largest six landfill companies had more than 80% of the market across the UK, but had a smaller share in northern England, Wales and Scotland.
