This book proposes the use of waste from oil drilling and sugar cane bagasse ash in the production of ecologically friendly soil-cement bricks. It offers a viable alternative to the traditional bricks available on the market, which use wood as fuel: manufacturing bricks from waste is less costly and does not require the consumption of trees and forests. It also proposes an alternative to the current discharging of the above-mentioned types of waste in sanitary landfills, avoiding additional environmental problems.
