Mega cities accommodate thousands of people every day, attracting them for the various opportunities it can provide to the inhabitants in terms of income and services. Cities are expanding both horizontally and vertically to accommodate this huge number of people every year. Thus, the success of waste management systems, both in developed and developing countries depends on a holistic waste management planning and adequate facilities. A significant amount of health and environmental problems are created by the improper waste management systems.

 The main key challenges are storage, separation and collection of various types of waste from residential areas. Lack of common and uniform waste infrastructures is highly visible in housing sectors. In addition to this difficulty, residential buildings which are increasing every year are of different types such as single-unit, low-rise residences, multi-unit apartments, high-rise apartments and apartment complexes with both low-rise and high-rise apartments. Most of the residential housings do not meet the rules of the National Building Code. In addition, proper guideline on waste management systems is also absent in the National Building Code. This discrepancy creates additional challenges to the waste management authority. Thus, the number of high-rise residential building is increasing significantly. It is important to understand that the people living in high-rise residential buildings would have different socio-economic conditions compared to other residential buildings. Hence, waste generation and management is also different in high-rise residential building compared to other housing types.

Steps which everyone must follow for a hassle-free and hygienic ambience

>>Reduce your use of materials. Apart from anything else, this saves your money.

>>Reuse materials. This saves more money.

>>Send materials off to be recycled. This preserves scarce resources.

>>Only when you have tried the first three options, should you dispose off material.

>>Ensure that public access areas are not polluted with litter.

>>Promote and practice waste minimisation through the waste management hierarchy: Avoid, Reuse, Recycle or Reprocess and only as a last resort dispose.

>>Where possible, choose or specify items with less or no packaging. Although packaging is important for food safety and freshness and to prevent product damage, excessive packaging is not necessary. Avoid packaging with lots of shrink wrap, boxes full of polystyrene balls, and boxes inside boxes. Insist on non waxed cardboard boxes instead of polystyrene crates unless the polystyrene is returnable and therefore reused!

>>Where possible, give preference to items with recyclable or reusable packaging:

>>Biodegradable cardboard coffee cups, waxed cardboard drinking cups and straws, and cardboard hamburger boxes and chip buckets are now available from most suppliers.

>>There is also a range of fully reusable cups, plates, containers, knives and forks which can be reused.

>>Encourage to use recyclable paper bags or sell reusable bags rather than plastic bags.

>>Reuse items within stores as much as possible (e.g. hangers, cartons and bags).

>>Encourage to take items for reuse (e.g. hangers, cartons, and bags).

>>Dump the garbage in the garbage bins located anywhere outside.

>>Segregate your garbage in wet, metal, plastic, paper and glass category.

>>Developer can use the suctioning machine in the buildings which sucks the garbage around 2-3 kms which prevents the environment from epidemic diseases.
