Low-Carbon Epoxy Resin Enabling Carbon Reduction and Circular Use in Taiwan’s PCB Industry
■ Supporting the PCB Industry in Carbon Reduction
▶ In response to the domestic PCB and system manufacturers’demand for green and lowcarbon
solutions, low-carbon epoxy resins have been developed using bio-based FDCA
and recycled raw material rBPA, achieving over 30% reduction in resin carbon emissions.
▶ ITRI has facilitated collaboration among domestic resin manufacturers to develop pilotscale
synthesis technologies for low-carbon epoxy resins. The material will be further
integrated with downstream manufacturers for use in power supply substrate applications,
with an estimated annual carbon reduction exceeding 10,000 tons.
■ Closing the Loop—Converting Waste Plastics Back to Materials
Circular Use of Recycled/Renewable Materials to Meet Brand Requirements for Recycled Content
■ Technical specifications
▶ Mechanical recycling products often fail to meet the high-quality requirements of applications such
as transparent or food-contact materials. Chemical recycling can depolymerize waste into reusable
monomers, but traditional external heating methods are limited by poor heat transfer, leading to high
process temperatures and energy consumption.ITRI has integrated low-energy microwave heating with
a twin-screw extrusion system to develop a continuous microwave pyrolysis process, converting waste
resources into high-quality feedstocks instead of incineration.Through pilot-scale demonstration and
system verification, this technology helps domestic industries secure key low-carbon raw materials(e.g.,
rMMA, rSM)to meet global brands’recycled-content requirements for new products.
▶ Taiwan produces 2.6million tons of polyolefins(PE+PP)annually. However, due to regulatory and brand
requirements mandating 30%recycled content in packaging materials by 2030, there is an urgent need
to develop recycling and process technologies to bridge the circular feedstock gap. ITRI has developed
a pyrolysis oil upgrading process that converts waste plastics into recycled naphtha. In parallel, ITRI has
also developed novel impurity-removal adsorbents and integrated hydrocracking/hydrogenation catalysts,
enabling the upgrading of pyrolysis oil to near-naphtha-grade quality. To accelerate deployment, ITRI has
established a demonstration and collaboration alliance, connecting upstream and downstream partners to
build a comprehensive circular supply chain.
▶ Amid the global trends of net-zero carbon emissions and green manufacturing, ITRI has developed a
dynamic modification technology that utilizes agricultural and fishery waste as the main raw materials to
synthesize a thermoplastic plant-based material(TPM). When blended with natural rubber, TPM exhibits
both excellent wear resistance and elasticity, overcoming the limitations of conventional technologies. The
material has successfully obtained USDA BioPreferred®certification with a biobased content exceeding
95%, marking a significant milestone in Taiwan’s sustainable footwear material technology.
