Organic Waste is generally reported to comprise Garden Waste and Food Waste and arisings total around 23,000,000 tonnes per year. It generally excludes Agricultural Waste (including manures and slurries which total around 90,000,000 tonnes per year) and Sewage Sludge (which totals around 2,000,000 tonnes per year)[1].

Overview

Organic waste is waste that is biodegradable, generally reported as Garden Waste and Food Waste. Whilst other wastes have an organic and/or biological content (such as Sewage Sludge and Agricultural Waste manures and slurries) they are separately reported.

Anaerobic Digestion and Composting (either Windrow Composting or In-vessel Composting) are the treatment methods for dealing with organic waste, and are key to diverting waste from landfill and producing renewable energy and sustainable fertilisers.

Macro Tonnage

The most recent information published by DEFRA [2] is based on 2016 data, with WRAP data for Food Waste from 2018[3] and organic waste generally from 2008[1]. The macro numbers under-report the total organic waste arisings in the UK as a whole as they exclude:

  • Organic Waste which is within general mixed waste (i.e. DEFRA only report segregated materials)
  • A large proportion of Agricultural Waste which is Food Waste (and hence Organic Waste) which is not reported (i.e. reject crops or crop wastage that is ploughed back into fields)
  • Other organic waste streams that are separately recorded (i.e. Sewage Sludge and Agricultural Waste manures and slurries)

WRAP Figures

WRAP in their organics report (dated 2008)[1] reported the following total arisings:

Organic Waste MSW Arisings (Tonnes) C&I Waste Arisings (Tonnes) Total Arisings (Tonnes)
Food Waste 6,100,000 5,700,000 11,800,00001
Garden Waste 6,400,000 4,200.000 10,600,000
Other 0 2,600,000 2,600,000
Total 12,500,0002 12,500,000 25,000,000
  1. The table is superseded by the figure below, showing the reviewed position of WRAP for Food Waste at 9,500,000 tonnes in 2018 (a reduction of around 2,300,000 tonnes) taking the total organic waste arisings to around 23,000,000 tonnes.
  2. Within the report WRAP indicated that 3,612,000 tonnes of the total arisings shown was collected, the majority of which was Garden Waste. Food Waste collection has increased since that time to around treble that reported as collected (c. 780,000 tonnes) and an increase in composting at the home (c. 530,000 tonnes). This has resulted in WRAP now reporting 1,300,000 tonnes of collected Food Waste. With Garden Waste reasonably static this means the 3,612,000 tonnes has increased to around 4,600,000 tonnes.


As noted above, WRAP in their most recent report [3]identify around 9,500,000 tonnes of Food Waste, of which 6,600,000 tonnes was from household sources with the following graphic summarising their findings and further explained on the Food Waste page:

DEFRA Figures

As set out above, the DEFRA macro numbers only report segregated organic waste and identifies three categories of wastes:

Reported by DEFRA as Generated in 2016 Tonnes
Animal & Mixed Food Waste 3,056,065
Vegetable Wastes 6,019,100
Animal Faeces, Urine & Manure 114,422
Total 9,189,587

The categories are split into six potential sources, as are all the DEFRA figures, summarised in the pie charts and data tables below:

From the information above, 4,959,851 tonnes is reported as household (54% of the total) and slightly more than the estimated figure of 4,600,000 tonnes above (mainly as a result of Garden Waste assumptions). The tonnage reported as C&I Waste of 4,063,247 tonnes (45% of the total) will be predominantly Food Waste, with only incidental other tonnage captured from other sources. This tonnage is higher than WRAP figures.
