Dong Hai Feng Green Pig Farm with Negative Pressure and Water Curtain

Background and Objectives

  1. TSC's livestock business is cooperating with government policy by promoting "biogas power generation in pig farms". With a focus on production, environmental protection, and economic benefits, we have constructed a green energy pig farm combining negative pressure ventilation and water curtain, biogas power generation, and solar photovoltaic systems in Dong Hai Feng Agricultural Circulation Park.
  2. This project involves an investment of 680 million NT dollars with the aim of becoming a demonstration site for modernized livestock farming with a focus on sustainability.
  3. On December 14th, 2022, Dong Hai Feng Agricultural Circulation Park received certification from the Ministry of Environment as an environmental education facility.

Implementation Status

  1. The construction was completed on October 18th, 2019, and trial operations commenced. By June 2020, the trial operations were successfully completed, and on July 14th, 2020, the facility was officially inaugurated.
  2. It received the highest level of circularity maturity "Optimizing" in the BS 8001 Circular Economy Certification.

Future Development Blueprint

  1. We will promote collaboration with young farmers to implement professional pig farming practices. Additionally, we will ensure proper collection of pig manure and other waste materials for processing by biogas centers, thereby achieving a zero-pollution farming process.
  2. Utilizing modern anaerobic digestion technology, we will convert organic matter into energy (methane) through microbial action and transform it into electricity. This not only promotes green energy but also reduces greenhouse gas emissions.
  3. We will promote the recycling of biogas residue and slurry back to the fields for reuse. Through field experiments comparing the fertilization effects of biogas residue and slurry on different crops, we aim to promote their use as organic fertilizers.
  4. We will continue to develop environmental education programs suitable for different age groups, aiming to achieve the goal of lifelong learning in environmental education.


  1. Annual production of approximately 40,000 pigs.
  2. Livestock biogas produces around 3.8 million kWh of electricity per year, which is equivalent to the annual electricity consumption of 1,084 households.
  3. A yearly reduction of 1,934 metric tons of carbon emissions, equivalent to the carbon sequestration capacity of 174 hectares of forest per year.
  4. Traditional pig farms consume 30 liters of water per pig per day, while in the Dong Hai Feng Agricultural Circulation Park, the water consumption per pig ranges from 5 to 10 liters per day, representing a reduction of over 75% compared to traditional pig farms.
  5. In 2023, a total of 1,942 individuals participated in environmental education activities.

Collaborators and Opportunities

TSC collaborates with local agricultural businesses to handle agricultural waste, turning waste into energy and ensuring optimal resource utilization. A pilot project for waste reuse has been successfully completed and approved by the Ministry of Agriculture. The project duration was from May 1st, 2020, to April 30th, 2021. During this period, Dong Hai Feng Agricultural Circulation Park assisted in processing 7,491 metric tons of pig manure from nearby pig farmers and 285 metric tons of waste fruit peels (lemons, pineapples) from surrounding cooperatives and juice manufacturers.
