Union Cement Corp, Philippines has teamed up with government agencies in its quest to tap alternative materials such as used tyres, waste oil, solvents, sludge, resins, plastic, nonrecyclable paper, paints and other products in its production process.  Union Cement has discussed the plan with suppliers of trash items in its plants located in Davao City, La Union, Bulacan and Misamis Oriental. Raymund C. Rondobio, Union Cement alternative and raw materials operations officer, said they have been looking into tapping indigenous materials with the use of sound technology that will result in good clinker production.  He said the company is also taking into consideration that the process is environment-friendly and follows the law, particularly the Clean Air Act.
