A nationwide survey on the state of discharge and treatment of municipal solid waste (wastes and excrement) in FY 2003 (April 1, 2003 - March 31, 2004) was conducted and the results have been summarized as follows. (Figures in parentheses are those of FY 2002.)
1. | State of discharge and treatment |
(1) | Total amount of discharge |
Total volume remained flat while slight decrease in per-capita volume. |
- |
Total volume | 51.61 million tons (51.61 million tons) |
|
- |
Per-capita volume | 1.106 kg/capita/day (1.111 kg/capita/day) |
|
The total volume of recycled waste and the recycle rate increased steadily while the volume of final disposal decreased by 6.4% compared to FY 2002. |
- |
Total volume of recycled waste | 9.16 million tons (8.64 million tons) Increased by 6.0% from FY 2002. |
|
- |
Reduction by intermediate treatment | 36.76 million tons (36.58 million tons) |
|
- |
Final disposal | 8.45 million tons (9.03 million tons) Decreased by 6.4% from FY 2002. |
|
- |
Reduction treatment rate | 96.4% (95.7%) |
|
- |
Direct landfill rate | 3.6% (4.3%) |
|
- |
Recycle rate | 16.8% (15.9%) Increased by 1 point from FY 2002. |
|
2. | State of waste incineration facilities |
Decrease in number by consolidating waste incineration facilities while increase in treatment capacity per site.
Treatment facilities having generation equipment is 19% of the total, out of which only 50 % has generation efficiency over 10%. |
(Data as of March 31, 2004.) |
- |
Incineration facilities | 1,396 sites (1,490 sites) |
|
- |
Treatment capacity | 193,856 tons/day (198,874 tons/day) |
|
- |
Treatment capacity per site | 139 tons/day (133 tons/day) |
|
- |
Incineration facilities utilizing waste heat | 995 sites (1,035 sites) |
|
- |
Incineration facilities with generation equipment | 271 sites (263 sites) (19% of the total) |
|
- |
Total generation capacity | 1,441 MW (1,365 MW) |
|
3. | State of final disposal sites |
Difficult situation in securing final disposal facilities continued unchanged as the remaining capacity decreased, while slight increase in remaining lifetime due to the decrease in volume of waste.
In Kanto and Chubu areas, wastes go out of the areas because the procurement of final disposal sites were not possible. |
(Data as of March 31, 2004.) |
- |
Remaining capacity | 137.08 million cubic meters (144.77 million cubic meters) |
|
- |
Remaining lifetime | 13.2 years (13.1 years) |
|
4. |
Status of waste management expenditure |
Decrease in total expenditure for waste management. Expenses for treatment and maintenance account for 80% of the total and increased slightly. |
- |
Waste management expenditure | 1,960 billion yen (2,395.6 billion yen) |
|
- |
Treatment and maintenance expenses | 1,536.2 billion yen (1,541.5 billion yen) |
