when do the bio-waste become bio-pollutants?
 Incineration , land filling etc make bio pollutants to a certain extent, even though not at a high rate.  Incineration brings in  air borne pollutants.The environmental impacts of incinerating containing biodegradable waste are mainly related to airborne emissions from incinerators, including greenhouse gas emissions, loss of organic matter and other resources contained in biomass.Nevertheless, some emissions will occur. There will also be some environmental burden from the disposal of ashes and slags, for example the flue gas cleaning residues, which often have to be disposed of as hazardous waste. Biological treatment: Composting, anaerobic digestion and mechanical-biological treatment also produce emissions (including greenhouse gases CH4, N2O and CO2). After stabilisation through biological treatment, the resulting material binds short cycle carbon for a limited time: it is estimated that in the 100-year horizon about 8% of the organic matter present in compost will stay as humus in the soil.
