Tackling VOC Emissions: Meeting Environmental Standards with Advanced Treatment Systems
Volatile Organic Compounds (VOCs) are harmful substances generated from industrial processes involving paints, solvents, and other manufacturing activities. Given their impact on the environment and human health, strict emission standards have been established worldwide, and proper treatment is required. In China, emission regulations have also become stricter. At “Plastic World,” three VOC exhaust pipes (G1, G2, and G4) have been set up at different treatment locations, incorporating two distinct treatment methods.
The first method is activated carbon box adsorption, which uses activated carbon to absorb VOCs. The second method combines spray, zeolite powder fluidized bed adsorption, and RCO catalytic combustion, utilizing these technologies to reduce VOC concentrations in the exhaust gas to meet regulatory standards. This ensures that the treated exhaust is safely released from high-altitude pipes.
Our company is committed to providing highly efficient gas treatment equipment that meets environmental standards by adopting the latest technologies. We will continue to improve these technologies to contribute to sustainable development for businesses.
Sustainable Manufacturing with Underwater Pelletizing Technology
As part of our commitment to sustainable manufacturing, we have adopted underwater pelletizing technology — a clean, efficient, and environmentally responsible method for polymer processing.
Unlike conventional air-cooled or strand pelletizing, underwater pelletizing uses a closed-loop water system to instantly cool and solidify polymer melts during granulation. This approach provides several environmental advantages:
- Reduces Emissions & Dust: The enclosed system minimizes dust and VOC emissions.
- Saves Energy: Water’s high thermal conductivity shortens cooling time and lowers total energy use by up to 20%.
- Minimizes Water Waste: Cooling water is filtered and reused in a closed cycle.
- Supports Recycling: Especially effective for processing recycled plastics, even those with impurities.
In addition to environmental benefits, this technology ensures high pellet quality and dimensional consistency — essential for high-performance materials such as engineering resins and medical-grade plastics.
We continue to pursue innovations that align product excellence with environmental responsibility.
Conventional strand pelletizing with water bath – higher environmental burden
Underwater pelletizing system – a more sustainable alternative
