Type Of Waste...

Municipal Waste 
 Waste originating in the community consisting of household waste from private residences, commercial waste which originates in wholesale, retail or service establishments, such as, restaurants, stores, markets, theaters, hotels and warehouses, and institutional waste material originated in schools, hospitals, research institutions and public buildings.
Industrial solid waste is solid waste resulting from or incidental to any process of industry, manufacturing, mining, or agricultural operations. Industrial solid waste is classified as either hazardous or nonhazardous.
Special waste includes any solid waste or combination of solid wastes that—because of its quantity, concentration, physical or chemical characteristics, or biological properties—requires special handling and disposal to protect human health or the environment. 

Industrial waste
Waste produced by industrial activity, such as that of factories, mills and mines. It has existed since the outset of the industrial revolution.
Much industrial waste is neither hazardous nor toxic, such as waste fiber produced by agriculture and logging.

Construction and Demolition Waste 
Construction and demolition waste is generated whenever any construction/demolition activity takes place, such as, building roads, bridges, fly over, subway, remodelling etc. It consists mostly of inert and non-biodegradable material such as concrete, plaster, metal, wood, plastics etc. A part of this waste comes to the municipal stream.
These wastes are heavy, having high density, often bulky and occupy considerable storage space either on the road or communal waste bin/container. It is not uncommon to see huge piles of such waste, which is heavy as well, stacked on roads especially in large projects, resulting in traffic congestion and disruption. Waste from small generators like individual house construction or demolition, find its way into the nearby municipal bin/vat/waste storage depots, making the
municipal waste heavy and degrading its quality for further treatment like composting or energy recovery.
