Environmental Policies

Noise Control

• Special casing for all heavy machinery to reduce noise.
• Use of ear protection to reduce noise for employees.

Waste Control

• Fuel used during production process is reused as fuel for concrete stoves at plant.
• Large metal pieces are recycled and used to make smaller parts.
• Spare metal pieces are sent to be recycled and reused.

Environmental Policies

Dust and Fume Control System

• Use of filters to catch dust during the assembly of the Catalytic converter.
• Use of wet scrubber to spray mist into the air to catch fumes from the assembly of the Catalytic converter and recycling of water used by wet scrubber.
• System to reduce spatter from welding.

Environmental Policies

Air Purification System

• Robots used to paint parts, for higher quality and 80% more efficient use of paint.
• Water walls are used to capture dust in the paint assembly line.
• Use RTO ovens to evaporate Hydrogen Carbon from painting process. Ovens help reduce Hydrogen Carbon emissions up to 95%.
• In 2010, Toyota began to replace paint/thinner compound with a water soluable paint, which helps to dramatically reduce dangerous emissions.

Wastewater Treatment Facility

Toyota places a great deal of importance on wastewater treatment, and has invested in wastewater treatment system valued at 100 million baht to deal with wastewater created during manufacturing and consumption at our factory. Wastewater is treated chemically and biologically, before it is re-used in the factory in the following ways:

• Water is used to cool the room of the factory facility to reduce temperature and save energy.
• Water is used to water plants at factory facility.
• Water is used to raise fish in factory ponds.
• Water is used to wash lavatory facilities in factory.
• Water is used to wash Factory Floor.
• Wastewater is passed through the Chemical Treatments system to precipitate suspended solids and heavy metal.

Environmental Policies

• Plastic waste is shredded and recycled.
• Large part shipments from spare parts suppliers to reduce number of trips to Toyota factories and reduce fuel and emissions that result from shipping process.

Environmental Policies

Waste Management

• Toyota has asked for the cooperation of spare parts suppliers to package parts in reusable packages, such as plastic boxes, to reduce the amount of foam and paper waste.
• Waste is separated and categorized prior to disposal.

Use of Solar Cells

Toyota has installed solar cells at the Samrong Plant facility, in order to lower energy consumption, and uses stored energy to help power our meeting rooms.
