Climate Change and Toxic Hazards: Before the Storm

Chemical recycling refers to an emerging and diverse group of technologies for which there is a need for well-founded data to assess their potential contribution to circularity and decarbonisation. To support decision-making and investment processes, life cycle assessment (LCA) is a key tool for assessing the impacts of these technologies.

The new product-oriented chemical industry has three categories of products with different key characteristics. The first and most obvious category is commodities, the same products that used to dominate the chemical enterprise. The key for producing these products is their cost. The second and third categories of products may be less familiar. The second category involves molecules with molecular weights of 500 to 700 and with specific social benefits. The most obvious examples are pharmaceuticals. The key to their production is their time to market, i.e., the speed of their discovery and production. The third category includes products where the value is added by a specific microstructure. The key to these products is their function. For example, I don’t care why my shoes shine after I have applied polish; I only care that they do shine. Customers pay a premium for such a function.

Compared with sewage and waste gas, the regulation and control of hazardous waste started late in China. However, with gradual improvements made to the system of sewage and waste gas regulation, the central government has been devoting greater efforts to strengthen the supervision of hazardous waste, introducing and revising a series of relevant regulations and policies. Due to frequent regulatory updates, uncertainties of policy orientation, and regional differences in supervision and law enforcement, enterprises may be confused about specific management requirements, which adds to the difficulty of compliance.
