Figure3-1 The Material Flow of Our Country

Note 1: Wet waste, etc.: Water taken in socioeconomic activities and water content included in waste (e.g. sludge, animal waste, raw sewage, waste acid, or waste alkali); and input of earth and sand as a result of economic activities (e.g. sludge generated by the mining, construction and waterworks industries and slag from the mining industry). Note 2: Energy consumption and waste generated during industrial processes: An estimation of water, etc., included in raw materials and released during the manufacturing processes of industrial products.

Note 3: Fertilizing: Sprayed fertilizer is not actually accumulated and will be decomposed in the soil; therefore, particularly it has been taken out from the net increase to stock. Source: Ministry of the Environment

construction such as materials for road base and cement.

Metal type circulative resources account for 6% of the entire amount of generation of wastes. Their contents are, scrap material from construction sites, scrap metal from iron and steel manufacturing/non-ferrous metal industries, metal processing scrap from machinery and appliances manufacturing industries, and such used household products as metal cans and home electric appliances.

Typical usages are electrical furnace iron manufacturing, and metal resources input for non-ferrous metal refining.

Fossil type circulative resources account for 3% of the entire amount of generation of wastes. They consist of waste oil from various manufacturing industries, plastics processing waste from plastic article manufacturing industries and machinery and appliance manufacturing industries, and used plastic articles from households and various industries.

Typical use of these circulative resources is as building materials for construction and as a reducing agent of iron ore and an alternative to coke in the shaft furnaces of the iron and steel industry.

## (2) Amount of waste generated

## A Status of municipal wastes (garbage)

The amount of total emission of wastes $ ^{*1} $ in FY 2006 was 52.04 million tons, or 1,116 grams daily per person; an overall decrease of 1.3% from the previous year (Figure3-2).

$ ^{*} $ 1 “Amount of total emission of wastes”=“Amount of collected wastes + amount of carried in wastes + amount of collected wastes by groups”

## B Status of industrial wastes disposal

The amount of total emission of industrial wastes across the-country in FY2006 was 418.5 million tons.

About 214.77 million tons (51% of the total amount) were reclaimed, about 181.93 million tons (43% of the total amount) were reduced by intermediate processing, and 21.8 million tons (5% of the total amount) were subject to final disposal. The amount of reclaiming refers to the total amount of directly reclaimed wastes plus recycled wastes generated from processed wastes produced by intermediate processing. The amount of final disposal refers to the total amount of wastes directly sent for final disposal plus wastes sent to final disposal after intermediate processing (Figure3-3).

## C The reduction of Greenhouse Gas from waste sector

The “Kyoto Protocol Target Achievement Plan” has set objectives concerning waste-related measures to reduce the emissions of Greenhouse Gas, and it aims to reduce about 7.8 million tons (carbon dioxide equivalent) in Year 2010. The Greenhouse Gas emission derived from wastes mounted to 44.8 billion tons (carbon dioxide equivalent) in FY2006, which is about 3.3 % of the total amount of Greenhouse Gas emissions (1.34 billion tons carbon
