Tasmania generated an estimated 771,308 tonnes of waste in 2017-18, the Environment Protection Authority estimated.

That was 62 per cent more than the 475,462 tonnes generated in 2008-09.

The amount of waste sent to landfill increased by just 10 per cent in the same period, the EPA estimated in its 2018-19 annual report (from 398,523 tonnes to 439,600 tonnes).

The most recent total was lower than the annual totals for the three years from 2010-11 until 2012-13.

" ... the amount disposed of to landfill has remained relatively constant and recycling appears to have increased five times and composting activities have tripled," EPA director Wes Ford said in the annual report.

"Factors contributing to these trends are likely to include the actual increased rates of recycling and composting, along with improved data collection and reporting."

Mr Ford said about 52 per cent of waste sent to landfill in 2017-18 was from the commercial and industrial sector.

Forty-one per cent comprised municipal waste and 7 per cent was demolition and construction waste.

The Central Coast Council's new FOGO (food organics and garden organics) kerbside collections are intended to reduce the amount of material going to landfill.

According to the council, about half of the contents of the average Australian household waste bin are organic.

Mr Ford said the latest data for wastewater treatment (for 2017-18) showed Tasmania had reused the highest volume of treated effluent to date.

He said 10.7 per cent of it was diverted from water to land, such as golf courses, agricultural land and municipal recreation areas.
