Full Utilization of Sugarcanes for Value-added Production

Background and Goals

1. With its 100 years of history in the sugar industry, TSC has undergone many transformations and changes following the ups and downs of international sugar prices. At present, although there are only two sugar factories and one sugar refinery still in operation in the country, TSC still adheres to the core value of sustainable development and its responsibilities to the society. Innovative manufacturing processes, such as value-added production, renewable energy and water reuse are adopted to fully use all resources that create value and reduce environmental impact at the same time. Full utilization of sugarcanes creates high added value for the industry that contributes to the goal of sustainable development and facilitates the win-win value for downstream customers of the sugar industry.

2. Along with the fierce competition for obtaining raw material, increasing cost of waste disposal, as well as the stricter emission standard for boiler waste gas, TSC has re-designed products and production processes that reuse resources in the sugar refinery in order to achieve the goals of zero pollution, zero emission, and zero waste and to become a benchmark for facilitating circular economy in the sugar industry.


1. TSC has been assessing the resources that have not been fully recycled or utilized in the sugar making process and is redesigning high value-added products and new processes that are highly efficient from the first step.

2. By holding various forums of new technologies as an information exchange platform for domestic and international professionals, these forums also allow TSC colleagues to obtain a deeper understanding of the cane sugar circular economy.

3. TSC keeps developing various new and advanced technologies to verify the technical feasibility of resource and manufacturing integration and thus establishes a new model of whole sugarcane utilization.

4. A set of high-quality syrup production equipment has been set up in Huwei Sugar Factory to produce customized flavor syrups, including brown sugar syrup, golden syrup, and sugarcane syrup. TSC is evaluating and developing value-added new products, such as fresh sugarcane juice, rum, and sugarcane dietary fiber powder. Compared with producing sugar or syrup from sugarcane, fresh sugarcane juice production requires fewer procedures and consumes less energy which matches the circular economy principles. Through the redesign of resources and products, TSC expects to reduce energy consumption in the manufacturing process, thereby achieving green production and resource recycling for high-value utilization.

5. After the semi-matured compost process, bagasse is provided to mushroom farmers as the cultivation medium. This turns misplaced waste into resources and extends the lifecycle of bagasse.

6. Shanhua and Huwei Sugar Factories have been awarded the raw material verification and processing verification certificates by Council of Agriculture (COA), local golden sugar and Taiwan Sugar Brown Sugar also been awarded the “Traceable Agricultural Products” certificates by the COA in 2021, which will further boost consumer confidence in TSC’s products and enhance competitiveness.

Future Development

1. Due to the advantage of its abundant biomass resource, TSC continues to fully utilize waste from the sugar factories (e.g., bagasse and filter cake) to develop bio-energy technology following the government’s policy and moves forward to the goal of net zero and environmental sustainability.

2. To fulfill downstream customers’ needs in carbon footprint disclosure and move towards a net zero future, TSC will progressively assess water usage, energy consumption, and greenhouse gas emission from sugarcanes growing to the final cane sugar production.

3. Food and beverage suppliers now use combinations of different forms of sugar (e.g., crystal and liquid sugar) as they take product differentiation, operation easiness, and transportation into consideration for increasing profits. Sugar producers like TSC thus need to adjust production lines accordingly to meet the rapidly changing demands from their clients.

4.To cooperate with the government's 2050 net-zero transition path planning, a  related research that CCS in bagasse boiler flue gas in Shanhua Sugar Factory will be started in  2023or 2024


1. Developing high-value sugar products, promoting bagasse as a substitute medium for mushroom cultivation, and assessing the gasification technology of bagasse residue will not only increase the company’s revenue and create added value but also attain the goal of resource recycling.

2. At present, sugar production waste such as bagasse, filtered mud, ash, and molasses could increase the sugar factory’s revenue by about NT$ 113 million per year through the recycling and high value-added production of the sugar industry.

3. At present, 70% of bagasse is burned as fuel for combined heat and power (CHP), and the generated electricity (about 10 million kWh) could be used for sugar production in the sugar factory. TSC is currently evaluating the enhancement of boiler energy efficiency and equipment upgrade to meet the T-REC standard.

4. Sugarcane contains 70% of water. Recycling evaporated water during the sugar production process could provide partial water supply for the sugar factory, and this could reduce the consumption of underground water by about 92%.

Collaboration Opportunity

1. Contract farming of organic sugarcane or traceable sugarcane:

Potential partners: Farmers, either land owners or land lessees of TSC, who are interested in eco-friendly planting of sugarcanes (young farmers are welcome).

Cooperation project: planting of organic or traceable sugarcanes. Purchasing price is promised by the contract.

2. Recycling of bagasse medium for mushroom:

Potential partners: Mushroom farmers who use grow bags and also the composting industry.

Cooperation project: Value-added utilization of bagasse recycling.

3. Value-added utilization of bagasse Refuse Derived Fuel-5 (RDF-5):

Potential partners: Gasification equipment manufacturer, heat and energy producer, biomass particle manufacturer and power generation from agricultural  waste.

Cooperation project: Planning of waste heat reutilization from sugar factory and bagasse energy.
