The amount of waste recycling across the Parliamentary Estate has risen to almost two-thirds as Westminster officials continue efforts to reverse 2015 figures.
The information came in a written question from Labour MP Kerry McCarthy to Lib Dem Tom Brake, who speaks for the House of Commons Commission, which is responsible for services across the House, the Palace of Westminster and the rest of the Estate.
Total waste collected fell by 26,524kg to 1,595,716kg in 2016, the second year in a row it had declined after peaking in 2014. Overall recycled waste rose by 6,740kg to 1,017,615kg, which is 63% of that collected.
Mixed recycling volumes rose to 382,439kg in 2016 after falling to 371,572 2015kg the year before. During the same period, food collected for treatment rose from 136,285kg in 2015 to 195,082kg and glass recycling went up 192,681kg to 249,855kg.
Parliament also recycles waste electrical and electronic equipment, consumables, metal, cooking oil, lamps and fittings.
Brake said in reply: “Parliament continues to explore new opportunities to recycle and recover waste in collaboration with its waste service providers.
“Parliament commenced a new waste contract in November 2016 [with Bywaters], and the specification for the services included a written requirement for a continual improvement approach to collaborative waste recycling improvement.
“It is the contractual duty of the waste service provider to give advance notice of changes in best practice and waste recycling technology, and to incorporate these into their service provision in the most expedient and effective way possible.”
