Creating a Recycling Society

The Tokyo Gas Group strives to create a zero-waste society by implementing its Guidelines for Promoting Resource Saving and Recycling and rigorously practicing the 3Rs of reduction, reuse and recycling of waste across the Group. Specifically, we seek to achieve zero waste emissions at production sites, reduce the amount of soil excavated during gas pipeline construction, reuse old gas meters and recycle used gas pipes (steel, cast-iron, and polyethylene pipes) at every stage of our business activities.

Total Volume of Generated Waste, and Recycling Rate


Third-party Assured
Every Group office produces various types of industrial waste, such as plastics from containers and packaging and waste from technological development and training as well as maintenance work at customer sites. The Group is strongly committed to waste separation and strives to recycle and properly handle waste.
We promote efforts at offices to reduce the use of copy paper, generate less paper waste and recycle used paper.

Promoting the 3Rs

Working to Reduce Waste

 
Efforts Concerning Excavated Soil

Underground construction works of gas pipelines entails excavating roads so, pit sand is used to refill gaps. Reducing the use of pit sand suppresses environmental destruction and lowers CO2 emissions generated by the vehicles transporting sand to construction sites. The Tokyo Gas Group strives to reduce the volume of excavated soil and the use of pit sand by laying pipes in shallow, narrow trenches and has adopted the non-open-cut construction method.
To reduce the use of pit sand further, we are pursuing 3R efforts such as increasing the use of excavated soil (reuse), improved soil, recycled road surface materials (recycle), and Eco-balls (reduce, reuse) for refill work.

Measures at Production PlantsThird-party Assured
We take steps to reduce waste toward achieving zero emissions (a landfill rate of less than 1%) not only at LNG terminals, but also at city gas production plants, power plants and district heating and cooling centers. In fiscal 2018, total waste from our business was 678 tons, of which 8 tons were subjected to landfill, and a landfill rate reached as small as 1.2%*1.
  • *1Calculation excludes hard-to-recycle industrial waste such as asbestos.

Initiatives for Reuse

 
Reuse and Recycling of Gas Meters Third-party Assured
We have played a leading role in reusing gas meters immediately after initial introduction of gas meters, prior to other gas service companies and companies in other industries.
Gas meters installed at customer sites are regularly replaced before the expiration of their 10-year certified life. However, we collect such retired gas meters, replace consumable parts, recalibrate them and reuse them for up to three cycles, which means 30 years at the longest.
In fiscal 2018, we reused 326 thousand gas meters, thereby succeeding the suppression of 1,358 tons of potential waste. Gas meters reused for three cycles have been materially recycled through our own channel and effectively used as material for new products by electric furnace makers and other companies.

Recycling Initiatives

 
Recycling of Used Gas PipesThird-party Assured
In fiscal 1994, we established a system for recycling used gas pipes, which are recovered during gas pipeline installation work. We have achieved an annual recycling rate of 100% for polyethylene (PE) pipes*1, which are recycled into raw materials for plastics, and for steel and cast-iron pipes that are reused as materials for metals. We also materially recycle PE pipes in-house by reprocessing them into such items as gas meter instruction tags that show how to restart gas delivery after shut-off in the event of an emergency such as big earthquakes.
  • *1PE pipes have been in widespread use since the Great Hanshin-Awaji Earthquake in 1995 because of their earthquake resistance and anticorrosive property.

Plastics Smart

Plastics Smart: Campaign led by Japan’s Environment Ministry to promote efforts aimed at resolving the global issue of marine plastic pollution through broad collaboration and cooperation among individuals, local governments, NGOs, companies and research institutions. Tokyo Gas has registered its initiative as a Plastics Smart campaign.

Dealing with Waste at Customer Sites

We promote the 3Rs at customer sites as well by controlling waste generation through the business value chain from the design stage, reducing container and packaging waste, to collecting used appliances.
System for Collecting and Recycling Waste such as Used Gas  Appliances (SRIMS)
Third-party Assured
We collect used gas appliances and waste from replacement works at customers and gas installation or home renovation work. Since August 1994, we have been operating our own Saving & Recycling Innovative Model System (SRIMS), which offers the combined benefits of reducing environmental impact and cutting costs. Under the system, we collect waste when we deliver gas appliances, parts and piping materials to partner companies. In fiscal 2018, we collected 7,391 tons of waste and recycled 6,938 tons.

Assisting Recycle Home Electric Appliances

The so-called “A Group”, mainly organized by Panasonic Corporation and Toshiba Corporation, collects and recycles Tokyo Gas-brand household gas air conditioners and clothes dryers. These are eligible for recycling under the Act on Recycling of Specified Kinds of Home Appliances (Home Appliance Recycling Law).

Reducing Waste of Containers and Packaging
Third-party Assured

We have made it a rule to collect discarded containers and packaging to reduce waste at customer sites when partner companies sell and install gas appliances.
Collected containers and packaging are recycled in the Saving & Recycling Innovative Model System (SRIMS). In fiscal 2018, approximately 558 tons of corrugated cardboard and 13.6 tons of polystyrene foam were recycled.
In addition, we work to reduce the quantity of containers and packaging for gas appliances.
These efforts include reducing cushioning through the redesigning of cardboard packaging, cutting back on the use of cardboard through shrink wrapping in plastic film, and adopting returnable packaging, in which packaging materials are collected and reused repeatedly.

Best Practices in Dealing with Waste from Various Business Activities

Dealing with Waste from Construction Work

The Tokyo Gas Group deals with waste from gas equipment installation work under direct contracts with gas utilities, gas pipe work at customer sites, installation of air-conditioning, heating and hot water systems, and home renovation work. We are making our utmost efforts to reduce such waste, which is mainly construction rubble and sludge, scrap metal, and woodchips.
 

Working to Reduce Waste in Installation Work for New Gas Equipment
We have adopted the prefabrication and precut method for piping work for the TES (Tokyo gas Eco System) gas/water heating equipment. Pipes and joints as well as other materials are processed at manufacturing plants and supplied as piping sets in time for installation work at each house. The only work necessary at the worksite is connecting and fixing the pipes to appliances. In addition, we are cooperating with manufacturers and installation contractors to promote this method, which generates less waste by requiring no onsite processing.
 
Working to Achieve Zero Mixed Waste in Gas Equipment Renewal Work
Replacement of equipment or pipes for our HEATS gas central air-conditioning and heating system installed at condominiums requires dismantling and removal work. While the scale of the work is relatively small, waste separation is limited by work periods and space considerations, which often results in disposal as mixed waste. The recycling rate for mixed waste is low, with most of it disposed in landfills. We have therefore reinforced our efforts to formulate a waste separation protocol at the planning stage of construction work in coordination with relevant parties and educating staff on waste separation. Consequently, we have achieved zero mixed waste from construction work and reduced the volume of landfill waste disposal.
