Keep up with policy trends: Give priority to continuous pyrolysis equipment
As global environmental regulations tighten, governments are pushing the industry in a greener, more efficient and more sustainable direction. Continuous pyrolysis equipment is a wise choice, especially when considering the following policy trends:
The government's ban on intermittent
Government ban: Many countries are phasing out traditional intermittent systems due to pollution and safety risks. For example, in 2023, the State Council of China has ordered the complete elimination of non-compliant fixed-bed batch gasifiers. Continuous systems use closed-loop operation and fully automated control, making them cleaner, safer, and more likely to meet future regulatory standards.
Continuous policy incentives
Policy incentives: The government provides subsidies, tax incentives and green financing for advanced low-emission equipment. Continuous pyrolysis machines qualify for such support because of their high energy efficiency and better emission control, helping investors reduce costs and attract ESG investment.
Easier to pass the EIA
Easier access to environmental approvals: Environmental impact assessments and safety assessments are easier to pass with a continuous system. Its steady-state operation and reliable emission control simplify the compliance process, speed up permit approvals, and reduce project delays.
