Initiatives for industrial waste recycling

The TEPCO Group is making active efforts to attain a 100% recycling rate of industrial waste, with the aim of minimizing the environmental load of its business activities. We are also striving to create a recycling society by pursuing various eco-conscious business activities by Group companies.

Achievements of TEPCO's recycling initiatives

In FY2001, we established the target of "achieving 100% recycling rate of industrial waste by FY2005," and practically achieved this target through Company-wide efforts. We came close to achieving this 100% target again in FY2009, as a result of continued efforts.

    Radioactive waste is not included in industrial waste, as it is separately governed by nuclear power laws and regulations.

Recycling initiatives by TEPCO Group companies

TEPCO Group companies have established a target of achieving a 100% industrial waste recycling rate by FY2010, and are implementing recycling policies. The Group Environmental Committee supports each Group company's efforts to increase recycling rate, as appropriate to their respective businesses.

In FY2009, 9 companies achieved a recycling rate close to 100%, and 7 a recycling rate higher than 95%.

Promotion of recycling businesses by Group companies

Members of the TEPCO Group exploit their business expertise to launch diverse recycling projects.

  • Sewage sludge recycling

Tokyo Electric Power Environmental Engineering Co., Inc., a member of the TEPCO Group, manufactures non-fired brick blocks made partly from sewage sludge incineration ash. In addition to incineration ash, these bricks also contain quarry dirt and molten slag, and are made almost 80% of recycled materials.

The bricks also offer outstanding water permeability and water retention, and can help mitigate floods and the heat island effect. Furthermore, the production process of non-fired bricks emits less CO2 compared to the production of fired bricks that consume fossil fuel.

  • Waste power generation

TOKYO WATERFRONT RECYCLE POWER CO., LTD., a TEPCO Group company, operates the recycling facility "Super Eco Plant" for industrial and medical waste. Metals, aluminum, slags, and other by-products of the recycling process are recovered, and waste heat is used to generate power. It emits less CO2 compared to simple combustion facilities.
