Recent decades, we have problems with environmental damage such as soil polution, solid waste, wastewater, and air polution, environment have problems every single sector. Biochar created by coconut shell waste that dried for two days to remove water content than coconut shell waste burned with pan using unused firewood during four hours. This paper will explain about biochar production using a hundred percent waste material and the impact of biochar to environment. Biochar can solve the heavy metals and organic pollutants in soil, biochar application decreased the concentration of As, Cd, and Cu in maize shoots, which depended upon amount of biochar addition, pH values of soils, and ability of metal to adsorb on biochar, applied biochar for environment that give reducing global warming effect, acidification, eutrophication, ozone layer depletion, summer smog, winter smog, pesticides, airborne heavy metals, waterborne heavy metals, and carcinogenic substances, biological attributes of biochar related, biochar could reducing arsenic and heavy metals content underwater, status of nitrogen species and elements of potential toxicity in soils. Thus, this research will be acceptable for everyone and can solve the environmental problems.
