  CONSTRUCTION WASTE  Quantityof waste is uncertain due to variety of estimation methods and varying pace of developmental activities in cities  About 25% to 30% of total solid waste is construction related. Of total 25 to 30 million tonnes of construction waste generated per annum , only 5% is processed. Type of construction Waste generated New construction 40 to 60kg per square metre Old construction 40 to 50kg per square metre Demolition 300 to 500 kg per square metre Construction Waste Generation

  Construction Waste RecyclingAnd Reuse  Recyclable waste includes metals, plaster, untreated timber, packaging material, concrete, masonry, insulation etc.  The unwanted waste is sold to vendors who sell it to recycling plants Or else the waste can be sent to recycling units directly. Waste generators who generate more than 20tons per day or 300 tons of waste per month are bulk generators. Collection and recycling costs may be 20% less for bulk generators.  Top soil can be retained and reused in landscape  Technology such as Mivan can be reused many times and recycled for use in different buildings

  Recovery Of Waste Recoveryof waste can be done through:  Mobile C&D waste recycling on site involving crushing, screening and magnetic separation  Semi mobile waste recycling using manual means and end screening  Stationary plant waste recycling involving crushing ,screening and purification  Intermediate collection centers can be provided every2to3km.  Land can be leased or acquired can be acquired for waste management recycling activities.  For every 20,000 tons of waste generated, a recycling plant is required.

  Recovery Of Wasteand Land fill  Recycling plants should be  planned for a period of 20 to 25 years.  Set away from habitable areas and sensitive zones  Surrounded by buffer zones, hedges, fences etc.  Have concrete access roads  All waste materials entering to be weighed  Amenities for health and sanitation provided to workers  Land fill should be done after considering all laws and regulations
