Donghua Tianye's industrial chain planning is based on PBAT/PBT and involves deep vertical development. Upstream, we strategically position ourselves in the core raw material industries such as BDO and succinic acid to extend the industrial chain. Downstream, we expand into modified products and autonomously research and promote various end products, including fully biodegradable mulch film, dust-proof nets, film bags, and daily necessities, accelerating the development of the entire industry chain of "BDO+PBAT synthesis+PBAT modification+PBAT products".

Additionally, we horizontally layout a series of industrial park bases for biodegradable material clusters such as PBS, PBST, PBSA, etc. This comprehensive approach enables us to establish a robust and sustainable industrial ecosystem that covers the entire value chain from raw materials to end products.
