4. Feature of the park

4.1 Leachate Treatment Plant

All these large water tanks could be considered as the purifiers of the leachate! This area was a landfill accepting wastes from the Daxi, Sanxia and Yingge area. The wastes dumped here were gradually decomposed by bacteria for many years. At the same times, the rainfall flowing through the decomposed wastes was accumulated as the leachate, and then, treated, recycled as the gray water resources.

Current status:
The leachate treatment plant was completed in 1993, and operated responsible  for landfill leachate treatment and pollution control. The treatment plant had an initial design capacity of 300 tons per day, and an average of 120 tons leachate per day is treated after the landfill was closed. The treated leachate could be followed the EPA standards before discharging.
Leachate Treatment Plant

Benefits in carbon reduction:
Parts of the effluent from leachate treatment plant  are recycled for usage in the park's toilets and cleaning equipments. This behavior is conformed to not only the pollution reduction but also the water resource conservation. 548 tons of water is conserved annually, which are equal to the reduction of 104.12 kg CO2emissions (0.19 kg of CO2 are produced for each 1 m³ of water used).

4.2 Landfill Gas to Energy (LFGTE)

The process of waste decomposition in the landfill produces a landfill gas containing methane and carbon dioxide. Methane, which is a flammable, odorless, non-toxic gas, is 23 times more powerful than CO2 as a greenhouse gas. Although methane is a greenhouse gas, it has a high energy value, and can be used to generate electricity. The park has implemented landfill gas control measures since 2002, and has installed 25 gas extraction wells, four well stations, and one landfill gas flarming facility. In addition, since 2005, the park has installed Taiwan's first mircoturbine landfill gas to energy facility (capacity 90 kW) for generate electricity. As a result, we transformed a pollutant into green energy through greenhouse gas elimination.
Landfill Gas to Energy

Current status:
We use landfill gas to Energy System to collect most of the methane generating from the landfill. The LFGTE facility produces enough green energy for the park self-sufficient in electricity, and electricity from Taipower is used only as a backup. Apart from conserving energy, reducing CO2 emissions, and keeping the Earth cool, we are improving environmental quality within the park and boosting the seedling survival. This work will stabilize the park and facilitate future land-use plans.

Benefits in carbon reduction:
Power generated from landfill gas makes the park self-sufficient in electricity. Up to 570,000 kWh of power can be generated annually, which is equal to a reduction of 363,660 kg CO2 emissions (assuming that  0.638 kg CO2 emission per kWh energy generated).

4.3 The Tree Bank

What should we do with all those large trees that must be relocated when roads are widened or public construction projects conducted? In order to provide these trees with a new home, starting in 2005, we have opened what we call a "Tree Bank" gives old trees to grow in a new place. Today, we have re-planted more 500 trees here. Remember to take a deep breath when you stroll through the Tree Bank.
The park also reduce approximately 200,000 kg methane emissions annually, which is equal to a reduction of 4.6 million kg CO2 emission (methane is 23 times more powerful than CO2 as a greenhouse gas).
The Tree Bank

Current status:
It is said that it takes many trees to create a forest. Planting trees can moderate the climate, purify the air, conserve soil and water, maintain water resources, landscape the place, soothe people's hearts, and provide a habitat for life. The existence of the Tree Bank expresses our hope that, in addition to economic development, we can cherish life and living things. We also encourage everyone to plant trees. Trees not only improve the living environment, but also reduce air pollution, lessen the emission of greenhouse gases, and provide many other benefits.

Benefits in carbon reduction:
More than 2,300 trees have been planted in the park thus far, and the vegetation coverage rate is over 90%.This is equal to a reduction of 28,750 kg CO2 emissions annually (large trees generally absorb approximately 12.5 kg CO2 from the atmosphere annually).

4.4 A Beautiful Garden--Greenhouse seedling area

In 2003, we built a greenhouse on the landfill for the seedling planting occupying 1480 m2. The greenhouse provides a good environment for seedlings to perform photosynthesis and absorb carbon dioxide. Low-tech methods were used to grow hardy plants that could be used to replant the landfill.

Current status:
Plants including houseplants, such as pineapple flowers, Aglaonema, and Pachira, can improve air quality inside the office. Various types of waste are also used as landscaping materials, including the frames from bag house and old household mattresses. Plants grown at the greenhouse are provided for landscaping the offices, cleaning the indoor air quality and free of charge to visitors. In 2006, the greenhouse has successfully grown crops such as tomatoes, strawberries, and sweet corn in elevated growing medium. Local students welcomed to learn about plant growth. The greenhouse gives an even greater significance for the park's restoration.
A Beautiful Garden

Benefits in carbon reduction:
The usage of rainfall collection in the greenhouse provides a saving of600 tons water resources annually, which is equal to a reduction of 114 kg CO2 emissions. The greenhouse produces 15,000 plants for landscaping the indoors annually, which is equal to a reduction of 1,700 kg CO2 emissions.

4.5 New Visitor to the Park—The Cherry Blossom Tree Area

Green is not the only color of spring! In the emerald green valley, who is this bright pink newcomer? We have been actively landscaping and replanting the park since the landfill closed in June 2000. Apart from the tong trees that landscape the mountain valleys with their white blossoms at the end of spring, we have also planted cherry blossom trees since 2008. We hope these cherries will engage in vigorous photosynthesis, thrive in the park, and add even more colors in the springtime.

Current status:
When it was closed, the buried waste in the landfill was still unstable, and growing on the landfill surface was harmful to the vegetations. We have treated the landfill gas and leachate produced by decomposition in the landfill. As a result, the seedlings survive  increasing greatly, and we can now successfully plant many types of trees to increase the park's biodiversity.

We hope that everyone who visits the park will have a chance take a deep breathe, release their stress, and give them strength to face next challenge in their life.

Benefits in carbon reduction:
A total of 810 cherry blossom trees have been planted in the park, which are equal to a reduction of 10,125 kg CO2 emissions annually (large trees generally absorb approximately 12.5 kg  CO2from the atmosphere annually).

4.6 Living in Harmony with the Environment—Green Home

In the Greater Taipei area wouldn't it be a good thing if people are able to live in the spacious landfill? Since the fully restored landfill is ready for change, why not build a house for living? The Green Home features green energy, low-carbon materials, and natural ventilation. People who live in this house can experience the meaning of LOHAS (Lifestyles of Health and Sustainability). When you visit the Green Home, you can experience a "three-low lifestyle"--low energy consumption, low water consumption, and low carbon emissions.

Current status:
What is a green building? It is a building that combines ecological, energy conservation, waste reduction, health considerations, and strives to minimize the use of resources. A green building takes advantage of the environment as effectively as possible, and seeks to produce minimal waste. It takes advantage of natural lighting, ventilation, temperature, humidity, and other natural resources to provide comfort and convenience. In the Green Home, you can use green electricity and water resources, while experiencing a farmer with the self-sufficient life. In the still of the night, you can listen to an insect serenade, stroll under the starry sky, and experience the joy of simple, healthy life.

  • The house is built with green materials which reduce carbon emissions by more than 50% compared with RC buildings.
  • Structural materials can be recycled and reused.
  • The house uses green energy and is self-sufficient (solar energy, wind power, biomass energy).
  • Rainfall is recycled as the flushing water in toilets.
  • Use appliances and plumbing which are certified to conserve energy and water resources.
