INTRODUCTIONPANAJI:

Location map of panaji

Panaji is capital of Goa and the headquarters of North Goa district.

Panaji is a costal city which is located on western side of the country along the Arabian sea.

It is a prime tourist spot both for national as well as international tourists.

This city has a high floating population since it receives about a thousand international and five thousand domestic tourists every day.

SCOPE OF THIS PRESENTATION:

Analysing the the total quantity of waste generated in the panaji city. Discussing the present situation on the solid waste management and

proposed new system. Details of disadvantages of present system and advantages of proposed

system.

SOLID WASTE:

Solid wastes are any discarded or abandoned materials. Solid wastes can be solid, liquid, semi-solid or containerized gaseous material.

TYPES OF SOLID WASTES

Municipal waste Hazardous waste Infectious waste

House hold waste Construction

waste Demolition waste Food, paper,

wastes Institutional waste

Non-bio degradable waste

Radio active waste Feritilizer waste

Hospital waste Disposal of

human corpses Dead bodies of

street side animals

Steps to follow solid waste management:

Source storage and segregation

Waste transportation

Dump sitesCollection and transportation

Processing for energy

recovery

Disposal to landfills

Recyclable materials separated

3R’s concept:

Reduce: Reduction can be achieved by keeping our requirements optimum

Reuse: Reuse of waste will increase its utility and will decrease the load on treatment.

Recycle: Recycling means completing the cycle of nature.

EXISTING SYSTEM:

Municipal solid waste is segregated in houses, hotels, restaurants, commercial levels.

Residential units and all the commercial establishments store their waste in a 2-bin system i.e Biodegradable (wet waste) and Non-biodegradable (dry waste).

hotels and restaurants are covered under 4-way dry waste segregation. 60% of the residential are under 4-way segregation of dry waste and stored in

240 litre trolley bins. Bio-degradable waste is collected on daily basis. Non-biodegradable waste from residential units and commercial

establishments is collected bi-weekly basis. Non Bio-degradable waste from residential complexes covered under 4 way

segregation and hotels and restaurants is collected on daily basis and collecte to sorting centre located at St. Inez, Panaji.

The non-recyclable waste is bailed to cement companies in Karnataka and dumped at one of the temporary site located in the city.

DISADVANTAGES OF EXISTING SYSTEM:

Sanitary workers involved have not been provided with appropriate Personal Protective Equipment (PPE)s

composting units is insufficient in numbers to process the bio-degradable waste.

land is scarce commodity and not available for setting up the required MSW facilities.

compositing units are difficult to manage and monitor in the city. Crude disposal of Construction & demolition waste is happening without

any facility for disposal and resource recovery. Present workshop located at CCP is lacking in space for parking the

vehicles Un-scientific management of slaughter house waste with no proper

arrangements for its safe disposal.

PROPOSED SYSTEM:

Design year of proposed ISWM system is 2040 of 100TPD capacity. 10 liter capacity bins of green colour for for bio-degradable waste and

20 liter capacity bin of black colour for for non-biodegradable waste. Primary Storage of solid waste colletd at the Municipal Market to be

done in 240 lites capacity trolley bins. Temporary storage of Construction & Demolition (C&D) Waste at

Zone level. At the Municipal Market, waste from 240 litre capacity trolley bins will

be transferred directly into 8 cum capacity refuse collector. Hotels, restaurants and commercial areas, the Bio-degradable (wet)

waste put in green polythelene bags and stored in the 240 liter capacity bins to be collected directly by 8 cum capacity.

Bio-medical Waste to be sent at the Goa Medical college facilities for the final disposal in environmentally sound manner.

A centralized MSW facility to be provided with the following facilities

A material recovery facility (MRF) for sorting and recycling of the dry fraction

Waste-to-Energy plant based on bio-methantion & composting facility. Electricity generated to be used for in-house plant operation. Reuse of construction debris for filling of low lying area. Reuse of mulched tree waste as structure material in the compost

plant. Storage and safe disposal of the E-waste.
