Waste Management and Reuse

          In 2020, the amount of general business waste handled included 26,006.26 tons for landfill, 2.16 ton for incineration, and 213,528.93 tons for reuse (compost or soil amendments). In 2020, the waste disposal amount increased by 18.32% compared with 2019.

          All pig carcasses and discarded afterbirths in all pig farms shall be destroyed, rendered or processed with measures necessary in accordance with the Statue for Prevention and Control of Infectious Animal Diseases and Waste Disposal Act, and shall not be cut, processed, transported, stored or sold for human consumption or intended for human consumption. Our Livestock Business Division complies with the government regulations and entrusts qualified rendering plants to handle pig carcasses and afterbirths in all farms with chemical processing procedures to avoid misappropriation by unscrupulous vendors, preventing them from entering the meat supply market, endangering the health of people in Taiwan and damaging the goodwill of TSC.



  • Reduction in the Output of Waste

          In 2020, the waste reduction measures were implemented in the manufacturing process, and the recycle ratio of waste reached 89.14%, increased by 3.15% compared with 2019. This was mainly because that the increase in sugarcane yield resulted in the increased processing volume of recyclable waste, including bagasse, filter sludge, soot, and fertile soil, and therefore, the recycle ratio increased accordingly.

Marketing Business Division 

Biotechnology Business Division


The new product packaging design of the Marketing Business Division is in line with the policy of limiting over-packaging of products announced by the Environmental Protection Administration (EPA), Executive Yuan, to reduce the use of packaging materials and generation of waste, easing off the environmental load. Take the packaging of the Clam Essence for example, the lining frame strengthens the structure and texture of the box with folded edges while the size of the gift box is reduced to meet the requirements of the prescription. In 2020, the Biotechnology Business Division continued to use 2,986,494 glass bottles with reduced weight for the Clam Essence Products, a 7.6% decrease in weight compared with the old glass bottles, which is converted to a 23,892 kg reduction in glass use, reducing the impact of glass to the environment.
Sugar Business Division
  • The Shanhua Sugar Refinery of Sugar Business Division changed business waste of bagasse and filter mud into recycled materials as the soil amendment, reaching the purpose of circular economy. In 2020, the Bagasse Company of Shanhua Sugar Refinery received 10,928.49 tons of bagasse internally and sold 9,320.79 tons externally; the filter mud is officially named Fertile Soil, and the Company received 15,904.1 tons internally and sold 3,529.37 tons externally, achieving the reuse of resources and reducing the use of chemical fertilizers.
  • In 2020, the egg cards of Trichogramma chilonis were provided to our self-operated farms and contracted sugarcane gardens. In addition, TSC was also entrusted to provide the eggs of corcyra cephalonica (stainton) as the materials to feed Chrysopidae to function as a pest control for fruits and vegetables, which can significantly reduce the use of pesticides.
Livestock Business Division
 To work in line with the government’s requirements of green environmental protection, in 2020, 39.7% of the pig manure slag produced in the livestock farms will be self-reused and fermented to environmentally friendly organic fertilizer for the farmers to use on the farmland to improve physical properties of soil, increase crop growth, yields of crops and the farmers’ benefits.
Agriculture Business Division

The tissue culture bottles used for the production of Phalaenopsis seedlings are reusable glass culture bottles instead of non-reusable plastic cases. From January to December in 2020, a total of 980,722 glass culture bottles were used, and all of them were recycled for reuse, with the reuse rate of 100%.


  • Whole Pig Utilization
           The Whole Pig Utilization Project is a 12-year project, starting from January 2017 to December 2028. The whole project includes Whole Pig Utilization 1.0 which focuses on hog carcass grading, processing of remaining parts, recycling waste such as excreta and non-edible parts; Whole Pig Utilization 2.0 which focuses on the refinement of pork, the high price of pork, and development of products for medical use that will start; Whole Pig Utilization 3.0 which aims at passing the SPF certification and applying the tissues and organs to the development of biochemical materials. In 2020, the actual performance of the Whole Pig Utilization 1.0: revenue NTD 10,010/per pig, gross profit NTD 868 /per pig, gross profit rate 8.68%.

  • The Use of Whole Sugarcane
           Through the redesign of products and process, value is added to the by-product of sugar refining, sugarcane bagasse, for the reuse of it. We have developed an innovative business model to provide materials of composted bagasse to mushroom farmers in the rent to own model and was awarded Innovation Award of the 2020 Taiwan Circular Economy Awards.
This circular economy model not only makes use of bagasse to replace natural sawdust in the cultivation of mushrooms but also reduces tree logging while increasing mushroom production. The residual nitrogen fertilizer in bagasse can even shorten the composting time, and the introduction of the recycling mechanism also reduces the processing costs for mushroom farmers. It not only extends the life cycle of bagasse but also achieves the innovative business model of secondary recycling and continuous reuse, creating not only the products but also the value, fully embodying the spirit of circular economy.
