What two factors have made china the largest producer of waste in the world?

Coal and construction industry.

Explanation:

China is the largest polluter globally, producing more harmful gases annually than Europe and the United States combined. The main factors of this pollution in China are coal and cement production. Coal has traditionally been a major polluter, and most Chinese power companies are just using pellets as a raw material. Cement production for the needs of the construction industry produces large amounts of harmful gases. Given that China is rapidly urbanizing, this is causing a high rate of pollution.
