Our Asia CMP Manufacturing and Technical Center in Hsinchu, Taiwan, is a global leader in manufacturing chemical mechanical planarization (CMP) polishing pads. The site’s application expertise serves the semiconductor chip manufacturing industry and other advanced substrate polishing applications. CMP pads play a critical role in the semiconductor industry by enabling advanced performance technology that can greatly affect the yield, quality and performance of many different types of electronics devices.
In 2021, in line with our Innovating Safer by Design and Enabling a Circular Economy objectives, the Asia CMP Center implemented a strategy to reduces its production of halogen waste by selecting raw materials with a less hazardous chemical profile and cooperating with local recycling technology companies to reuse, recycle and regenerate the byproduct.
Manufacturing processes at the Asia CMP Center generated about 810 metric tons of byproduct in 2020. Most of this halogen-rich byproduct must be removed by a specialized waste management company. Halogens are highly reactive and can be harmful or lethal to biological organisms when in sufficient quantities. This waste must be safely incinerated in specialized handling processes.
The Asia CMP Center implement a strategy to reduce its production of halogen waste by selecting raw materials with a less hazardous chemical profile. Without the halogen content, the polyurethane-based byproduct is a stable component. Its physical characteristics make the byproduct suitable for reuse as filler material in construction applications.
In 2021, we partnered with a local recycling technology firm to crush the byproduct to the desired size, then mix it with other components to create composite materials which can be used to create a base for polyurethane pavement. This pavement composite works well in airport runways.
After a successful pilot and a return on investment of approximately 2000% in 2021, this partnership has become a role model for safer, more circular manufacturing in Taiwan.
The Taiwan Institute for Sustainable Energy awarded the Asia CMP Center with the esteemed 2021 Taiwan Corporate Sustainability Award for its efforts, including using raw materials with less impact to the environment, process optimization to minimize the residues during manufacturing, utilizing new technology to transform hazardous waste to recyclable materials, and implementing water reuse technology and solar panels.
Compared to traditional antenna materials, the superior performance of DuPont Pyralux® improves as frequencies increase, enabling telecommunications innovations to advance a connected society.
BLUEDGE™ Polymeric Flame Retardant Technology eliminates the use of hazardous flame retardants with one that has inherently low toxicity, delivers required performance and is economically viable.
DuPont materials for advanced chip fabrication enable faster and more complex computing for smartphones and other electronic devices, while consuming less power per bit.
Sorek B, which leverages DuPont FilmTec™ membranes, will increase Israel's desalination capacity by 35% and set a new benchmark for efficiency, sustainability and a record low price of water through desalination.
Reduction of packaging waste is an increasingly important topic for the healthcare industry as it seeks to achieve a circular economy. Packaging for IV sets presents a unique design challenge because of the variety of structural components, the durability required and the need for more sustainable options.
In 2021, in line with our Innovating Safer by Design and Enabling a Circular Economy objectives, the Asia CMP Center implemented a strategy to reduce its production of halogen waste by selecting raw materials with a less hazardous chemical profile, and cooperating with local recycling technology companies to reuse, recycle, and regenerate the byproduct.
Reverse osmosis (RO) water treatment systems provide the finest levels of pressurized crossflow filtration but can require a significant amount of cleaning to combat biofouling that results in operational challenges. Biofouling is the deposition of micro- and macro-organisms on industrial cooling equipment. Unchecked, biofouling causes significant operational and economic problems.
Moving to a “dry” running conveyor belt system in the bottling industry will reduce maintenance down time and amount of wastewater than requires proper disposal. DuPont and Regina have developed an innovative conveyor solution that reduces energy consumption and extends useful life.
