Stone crushers give rise to a substantial quantity of dust emissions, which create health hazards. It adversely affects visibility, reduces the growth of vegetation and hampers aesthetics of the area.
The National Capital Region generates 10,000 tons of municipal solid waste per day, much of which is eventually burned. Wastes that are non-biodegradable, when burnt, give rise to lot of carbon emissions which add to the particulate pollution to the air.
