Pollution Statistics (T4)

Question 1

As of 2001, around …… % of waste from households was recycled compared to …… % in 2001/11

Answer 1

As of 2001, around 40 % of waste from households was recycled compared to 11 % in 2001/11

Question 2

Since 2006/7, the average residual waste per person has reduced by …. Kg to ….. Kg/person/year

Answer 2

Since 2006/7, the average residual waste per person has reduced by .76 Kg to 275 Kg/person/year

Question 3

….. % of commercial and industrial waste was recycled or reused in England in 2009, compared to …. % in 2002/3

Answer 3

52 % of commercial and industrial waste was recycled or reused in England in 2009, compared to 42 % in 2002/3

Question 4

… % of municipal waste generated in the UK is sent to landfill, compared to a European average of …. %

Answer 4

55 % of municipal waste generated in the UK is sent to landfill, compared to a European average of 40 %

Question 5

According to RecycleNow, recycling in the UK saves more than …….. tonnes of carbon dioxide a year - equivalent to taking ……. cars off the road

Answer 5

According to RecycleNow, recycling in the UK saves more than 18 million tonnes of carbon dioxide a year - equivalent to taking 5 million cars off the road

Question 6

The UK produces approximately …… tonnes of food waste a year and about …… tonnes of animal slurry and manure, which could realistically be available for utilisation by ………. digestion technology. In England this could generate at least …… TWh electricity per year by 2020 (a heat equivalent of ….. TWh). The UK Al water industry already treats ….. % of sewage sludge by anaerobic ………, and generated around 1TWh per year of electricity in 2010

Answer 6

The UK produces approximately 7 million tonnes of food waste a year and about 90 million tonnes of animal slurry and manure, which could realistically be available for utilisation by anaerobic digestion technology. In England this could generate at least 3-5 TWh electricity per year by 2020 (a heat equivalent of 6-10 TWh). The UK Al water industry already treats 66 % of sewage sludge by anaerobic digestion, and generated around 1TWh per year of electricity in 2010

Question 7

The diversion of biodegradable wastes to anaerobic digestion can reduce greenhouse gas emissions from landfill. Give an example of this…

Answer 7

Capturing the bio gas from one tonne of food waste will save between 0.5 and 1 tonne of carbon dioxide equivalent

Question 8

Direct emissions from the waste management sector in the UK accounted for …. % of the UK’s total estimated emissions of greenhouse gases in 2009 (or ….. tonnes of carbon dioxide emissions) compared to ….. tonnes of carbon dioxide emissions in 1990. Of the 2008 total, … % arose from landfill, …% from waste-water handling and …% from waste incineration

Answer 8

Direct emissions from the waste management sector in the UK accounted for 3.2 % of the UK’s total estimated emissions of greenhouse gases in 2009 (or 17.9 tonnes of carbon dioxide emissions) compared to 59 tonnes of carbon dioxide emissions in 1990. Of the 2008 total, 89 % arose from landfill, 10% from waste-water handling and 2 % from waste incineration
