Abstract
As an important role in national economy, chemical industry has polluted the environment because of high energy consumption, behindhand technology, high material loss and so on. Life circle assessment (LCA) is one technology for evaluating the full environmental consequences in the entire life circle from raw materials acquisition, manufacturing to final disposal. As one new method of environmental management and preventive protection, LCA is mainly applied to evaluate the environmental load of a kind of production, working procedure and manufacture activity by the quantitative analysis on the usage of energy and material and the let of offal. LCA was introduced into the chemical industry field in the 1990s. On the basis of studying LCA theories and methods, a LCA system for chemical products (CP-LCA) is established according to the characteristic of chemical products and the properties of resource, environment and personal health. The establishment of evaluation system will improve the work efficiency of valuators.
