Waste Management

Waste Production and Recycling

VisEra implements green manufacturing and upholds the waste management principle of “minimizing waste output and maximizing resource recycling”. We prioritize “material recovery” and “energy recovery” instead of incineration and landfill to maximize the use of resources. VisEra’s sales, production capacity, and process innovation has risen rapidly since 2020, and the use of chemical materials, consumables, and machine line cleaning and maintenance consumption increased significantly. In addition, our process innovation allowed us to use new materials, and we have thus produced a large amount of general and hazardous waste that are different from those in the past. Due to the technical and environmental constraints of waste disposal, the total annual material recycling rate has dropped from 74% to 55%. In 2021, VisEra began searching for waste disposal companies other than incineration/landfill operators to replace waste processing by incineration. We also worked with the Foundation of Taiwan Industry Service on the separation and purity enhancement of waste materials that would otherwise have no reuse value and converted them for use as auxiliary fuel. The fuel is used in lieu of traditional fuel that causes high pollution such as coal and natural gas. As a result, the recovery rate (including energy recovery) exceeded 90% in 2022. In 2022, the waste recycling volume reached 2,182 tons/year and the landfill rate was 0.21%. The landfill rate has been consistently lower than 1% for 17 consecutive years after the inauguration of the plant.

Note 1: Material recovery processing refers to any waste treatment that does not involve incineration or landfill. Waste treatment by physical, heat treatment, reuse, etc. to produce reusable materials or products are considered material recovery.
Note 2: Alternative energy refers to the use of waste materials as fuel to produce heat (generally in the form of steam), which is then used to produce electricity with a steam turbine generator. Alternative energy generates both heat and electricity. The heat in the form of steam and electricity can be supplied to companies in the industrial zone.
