A helping hand for BBMP

Understanding the magnitude of the garbage mess, many non-profit and private organisations have come forward to help the Bruhat Bangalore Mahanagara Palike (BBMP) in waste recycling.

NobleExchange Environment Solutions Pvt Ltd (NEX) is one such organisation which has promised to play a major role in recycling of wet waste generated by bulk generators.

To address the issue, the organisation has been in discussion with the BBMP commissioner Rajneesh Goel.

KS Girish Kumar, Regional Manager of NobleExchange said, “We will not charge any money or demand funds from the BBMP. However, we have asked for a piece of land in the BBMP limits to carry out the process of recycling wet waste accumulated by bulk generators in Bangalore city.”

On its part, the Palike had already appointed an expert committee to look into waste disposal by bulk generators and Rajneesh Goel had also directed all the eight zonal commissioners to issue notices to 20 big bulk generators in their zones and collect the status of garbage management.

In such a scenario, this initiative will be of great significance to the bulk generators. Informing further on the initiative, Girish said, “We had a discussion with the hotel association president Vasudev Adiga and he has assured that they will give us their full cooperation.

We will talk to other big institutions as well and try to include them in our proposal to generate biogas.”

Proposal Outline

 BBMP to provide NEX (NobleExchange) 10 acre industrial land to design, build and operate 500 TPD food waste - energy processing plant for 50 years

BBMP ensures permissions for NEX to pick-up and transport organic waste from institutional waste generators up to central processing plant

NEX will provide an odourless waste storage system where organic waste generated can be stored

NEX's waste trucks will pick up waste from containers on a daily  basis. The disposal system is automated, drip and leak proof

NEX offers Compressed Biogas (CBG) to institutional customers for replacement of LPG or power from renewable source

The Process

A secondary level segregation plant at central site ensures separation of organic waste from other inorganic materials (waste from hotels, restaurants, etc.). The central processing plant is an anaerobic digestion system (CSTR technology) with water based cleaning, scrubbing and compression system that converts the organic waste slurry into CBG. This CBG/Electricity produced at the processing plant will then be marketed to institutional clients for replacement of conventional energy sources such as LPG, diesel, kerosene, furnace oil, etc. Further, the by-products generated from the process will be nitrogen rich and can be used as organic fertilizers. Waste water from the system is re-circulated to ensure minimal fresh water requirement or discharge.

Benefits of bio-degradable waste

It gives a firsthand solution to treat waste at source

The use of renewable energy reduces the carbon dioxide emissions

By capturing uncontrolled methane emissions, the second most important greenhouse gas is reduced

Biogas could increasingly replace LPG & can take the load of power generation

The fertilizer which comes from a biogas plant contains three times more nitrogen than the best compost made through open air digestion. Bio-fertilizers are cost effective and eco-friendly supplements. They provide a sustainable source for nutrients and healthy soils

Methane is a significantly more powerful greenhouse gas than carbon dioxide Containing methane and converting it to carbon dioxide will neutralise its effect on global warming

Biogas is considered to be carbon neutral

As biofuel is the product of recently consolidated atmospheric carbon, it is also considered to be a highly renewable resource

Minimum waste collection expenses
