Ventec is committed to environmental sustainability and promotes waste reduction
and management at the source. The PCB-materials process generates various wastes—
such as empty drums, adhesive/liquid wastes, copper-bearing sludge, acetone and
spent activated carbon—some of which are hazardous industrial wastes. To comply
with applicable laws, we continue to invest in pollution-prevention facilities and assign
dedicated personnel for daily inspection and upkeep to ensure stable system operation
and effective pollution control. Both general and hazardous wastes are removed and
finally treated by qualified contractors approved by environmental authorities, with leakand spill-prevention measures implemented during transport to mitigate environmental
risks.
In 2024, total waste generated across our four operating plants was 1,850.38 metric tons,
of which non-hazardous waste accounted for 92.81% (1,717.39 t) and hazardous waste
for 7.19% (132.99 t). To address increasing complexity in waste types and treatment,
the Shenzhen Plant implemented a Hazardous Waste Management Plan in 2024 to
strengthen classification and storage, anti-leak measures, fire and theft prevention—
ensuring compliant storage and disposal in line with local environmental regulations.
Following the 3R principle—Reduce, Reuse, Recycle—we optimize processes and resource
use to advance circularity. At the source, we replaced wooden pallets with plastic pallets,
extending service life, reducing resource consumption and pallet waste, and—thanks
to insect- and rot-resistant properties—further reducing the need for chemical coatings
and associated risks. For reuse/recycling, we operate an organic-solvent recovery
system: acetone recovery rose from 49 t (33% recovery) in 2023 to 66 t (38%) in 2024,
underscoring our commitment to 3R.
