Would you like to have a beautiful fence sitting between your house and the factory where you work? A living fence, of neither steel nor brick, that flowers and grows?
People walk along PTT’s new ‘greenery fence’ designed to hide industrial blight, thereby improving residents’ quality of life.
At the PTT Eco-Industrial Zone in Rayong's Map Ta Phut area, the giant energy conglomerate has developed a "greenery fence" surrounding its new bio-petrochemical estate, with 55 floral species growing along it. With a width of three metres and 3.5 metres high, the fence is made of soil blended with organic fertiliser and livestock waste.
It is a pilot greenery fence on five rai of land designed to be a protection strip. Some 90% of the plants are still alive after being planted a year ago.
PTT chief executive Pailin Chuchottaworn said the company is developing another 30 kilometres of greenery fence plus 160 rai of green space surrounding 1,500 rai of PTT's estate. Inside the fence are bioplastic plants for succinic acid, lactic acid and biofuels, which will be developed more over the next three years.
Locals will seed the area, and PTT will buy back seedlings at a reasonable price to ensure income throughout the year.
The greenery fence is a technique that originated from the prominent Japanese botanist Akira Miyawaki, who discovered a way to create a natural forest from a degraded green field. His idea was picked up by Japanese industrial operators as they made greenery fences for 1,200 workplaces around the world including the new Toyota Motor factory in Thailand.
The greenery strip reduces the normal growing period of plants significantly. This technique uses local plants such as Siamese Rosewood and rubber trees by planting four per square metre. The floor of the fence is covered with fragrant floral plants such as ginger, gardenia and bullet wood to attract insects. More animals are needed to make the fence feel and look like a forest, and irrigation will be provided for a year and a half.
Two more years of surface grooming are needed, then it will belong to Mother Nature. The selection of floral species is also crucial. Staff applied His Majesty the King's advice by blending fast-growing and slow-growing trees.
Verapong Chaiperm, governor of the Industrial Estate Authority of Thailand, said this project is aimed at being Thailand's first eco-friendly industrial estate, which the IEAT will promote for the next generation of industrial real estate.
The fence grows one metre per year, and PTT thinks locals may eventually forget to notice what is on the other side.
