Solar cell panels installed on the roof of the plant
The construction of Hamamatsu Factory's Hosoe Plant to produce outboard engines was completed in Hosoe-cho, Inasa-gun in Shizuoka Prefecture in September 2001. The Hosoe Plant, located near Lake Hamana, is regarded as Honda's environmental benchmark plant for the 21st century, and it will be the site for the implementation of Honda's Green Factory concept. We planned the construction based on the results of an LCA to quantify the environmental impact.
(1)Environmentally-friendly planning and design
•
Effective use of water resources/Zero wastewater in the production process
·
Use of recirculating water for checking completed outboard engines
(Closed system)
·
Use of rainwater for flushing toilets and as water supply for the cooling
tower (utilization ratio of 40%)
•
Higher energy efficiency and reduced CO2 emissions
·
Highly efficient production system (Line integration from engine assembly to shipment to improve the production space efficiency)
·
Direct shipment of packaged products by transport containers
(reduced storage space and transport energy)
·
Energy saving by using reduced air pressure to drive tools
·
Energy-saving factory building (heat insulation) and equipment
(inverters, reuse of waste heat)
·
Solar power generation using next-generation thin film solar cells
(developed by Honda Engineering Co., Ltd.)
•
Introduction of constant monitoring devices for rain drainage
•
Harmony with the surrounding environment
(symbiosis with the local community)
·
Kind to birds (use of window glass that birds do not normally fly into)
·
Planting of 32,000 trees on the boundaries to create a local forest
·
Local residents allowed to use the playground
(2)Environmentally-friendly construction
•
Proper disposal of construction waste
·
By sorting and recycling waste, zero construction waste landfill achieved
•
Environmentally-friendly construction method
·
Reduction in the use of plywood from tropical forests by the use of wire mesh frames
•
Radical management of wastewater
·
Zero disposal of waste soil outside the construction site
·
Use of ISO 14001-certified constructors
·
Use of non-vibrating pile driving method and low-noise heavy machines
2. Honda Manufacturing of Alabama (US)
• Preventing oil leakages
Overhead pipes enable problems to be detected quickly, and oil drip pans are installed in the bottom sections of the pipes in case of leakage.
• RTO equipment to make VOC*2 harmless "Thermal Oxidizer"
The exhaust from the paint process is collected to one place and 95% of it is converted into CO2 and water using a ceramic catalyzer kept at a temperature of 800°C
Extensive pollution control measures create an advanced
environmentally-friendly factory Honda Manufacturing of Alabama, Honda's latest factory in North America, was established in Lincoln, Alabama in December 1999. Since November 2001, the factory has been producing the ODYSSEY (LAGREAT in Japan) and V-type 6-cylinder engines. The factory covers approximately 5.5 million square meters and employs about 2,200 people, including employees transferred from Japan. In establishing this factory, Honda set itself the goal of becoming a local company that people can look up to, and introduced various advanced environmental conservation measures. In addition to complying with the standards set by the PTI (Permit to Install) given by the EPA*1, we aimed to make the factory a model factory, keeping it in harmony with the surrounding natural area, including the abundant water systems. Measures to prevent soil and underground water pollution
By concentrating the oil supply facilities in one place, the factory minimizes the risk of oil leakage at the time of delivery. Overhead supply pipes are equipped with drip pans to collect oil in the event of pipe leaks. And treated wastewater is discharged through a double-walled effluent line to give special protection against leakage. Measures to prevent air pollution
In the painting process, water-based paints are used for intermediate and final base coats. The gases emitted by the drying furnace and the final clear coating process are collected and treated by an RTO (Regenerative Thermal Oxidizer).
