Municipal Solid Waste (MSW) has become a challenge for Urban Local Bodies (ULBs) throughout the world. Depending upon the country spending capacity; every nation generates a different quantity per capita of MSW. Third world countries generate 250 grams per capita per day, whereas developed nations generate up to 2000 grams per capita per day. MSW composition is variable, with moisture as the most challenging aspect when it comes to the development of a business model for sustainable practices, so there is an urgent need to develop sustainable alternatives for MSW from outdated landfills and even sanitary dump sites.
Generally, MSW projects are subsidized or publically funded. The cost to local governments / municipalities continues to rise with little or no hope for cost recovery. However, waste can be a valuable resource. This is already demonstrated in certain countries.
UNEP states that worldwide, there is a growing need for sustainable and coherent solutions to solid waste management problems. MSW seems to be more complex in developing and transitional countries, where the increase volume and type of wastes, as a result of economic growth, urbanization and industrialization, is becoming a burgeoning problem for national and local governments, making tougher to ensure an effective and sustainable management of waste ‘( WTE /Inter-American Development Bank handbook )
Controlled decomposition of MSW leads to resource recovery for sustainable waste management. INNOVATIVE ECO-CARE (IEC) has proprietary inoculum from GRAS (Generally Recognized As Safe by WHO) microbe for ‘Controlled Decomposition’ for efficient resource recovery. Our inoculum is known as RENERZYME a.k.a Re-Energy Enzyme.
Being a Mixed Microbial Culture, RENERZYME has an edge over other cultures or enzymes.
EFFECTIVE, EFFICIENT & ECONOMIC (EEE) Management is the critical issue in all country across world
There are different types of mechanical Drying technology available, but all are highly advanced & requires high capital cost. Majority of Mechanical drying technology requires excessive external energy, huge space, pollution control equipments, water treatment facility - for drying of MSW. All this equipment adds an additional process, that has got its own problems & limitations, which makes the drying of MSW as major obstacle in further application & processing integration.
Microbial Cultures of GRAS microbe contains organic acids, metabolites, organic salts etc. It can dominate local micro flora & fauna in no time. At the same time, it works to activate local dormant beneficial microbial species in the eco-system. NPB GRAS microbe & local beneficial microbe work in tandem to create synergies to take charge of the eco-system & generate temperature as high as 80° cent. This unique action is known as ‘Bio-Drying’.
During multiple cycles of biodegradation, a widely diverse population of micro organisms catabolises substrates through complex biochemical reactions to satisfy metabolic and growth needs, gradually leading to mineralisation of organic substances.
IEC (INNOVATIVE ECO-CARE PVT LTD) has a proprietary formulated product-line. Every product has been designed for specific field applications. As these products affect the local ecology, we took great care in designing, formulating and calculating the minimum quantity for the application.
Following are the details of the IEC Product Line and its ideology.
RENERZYME is an inoculum of beneficial microbes along with precursors.
CONTENTS: Lacto bacillus sporogenes, Saccharomyces Cerevicae, carbohydrates, minerals, water.
FOR BALANCING OF SOIL PH and BETTER PLANT NUTRITION ACTIVATOR is a special blend of organic acids. It facilitates culturing of Inno-Care by “activating” the beneficial GRAS microbes and deterring gram negative microbes during the fermentation process, etc.
IEC has developed a complete integrated package of complete MSW handling in EEE mode. The basket of technologies applied in MSW & delivered by IEC with single point responsibility are :
If we consider MSW as a resource, we should adopt a ‘0% Landfill Approach’, i.e. we should have ways & means to convert all the components of MSW into saleable products, in an eco-friendly manner. The following are the revenue models from our treatment & processing technology. All the revenue models may not be feasible at all the locations.
From recovered resource, RDF and Mixed Plastics would be useful to produce power. The following routes can be adopted for power generation.
Option no.3 is recommended for large capacities beyond 20 MW & upwards. It will reduce the multiple units and provide technological flexibilities, too.
Our focus at IEC Technologies is the generation of “smart” energy from MSW resources, which has all been made possible by the meticulous R&D behind our organic bio-drying agent and combined, with our 40 years of energy producing systems. We do not claim to have all the answers rather we hope that we can help to contribute and make this nuisance to ULB be a thing of the past
MSW Waste Management Dump sites are lately stacked up, tens of feet in the air with potentially high amounts of carbon rich biomasses. These soaring heaps of waste encourages anaerobic conditions for microorganisms, which along with nutrient availability from organic biomasses conceivably serves as quite favourable for Methanogens (Methane Producing Microorganisms) to thrive and produce high concentrations of methane.
Methane is highly flammable and can be flared up at ambient temperatures. Due to this, methane catches fire and eventually enflames the surrounding waste, which is potentially flammable matter. This leads to Fire and Smoke Hazards, inciting Public Health and Safety Concerns.
Along with the fire related hazards due to Methanogens some Malodorous compounds are also generated due to chemical reactions and other microbial activity, which is again a reason for public uproar due to the extremely antagonising stench.
Methanogens are anaerobic microorganisms which utilize sulphur as the final electron donor in the ETC (Electron Transport Chain). Methanogen activity is at its peak under absolutely anaerobic conditions. Methanogens has high activity at a neutral pH. Along with this, Ammonia and H2S are released at the same pH only. Methanogen activity is also dependant on the utilization of specific substrates for energy.
Renerzyme is effective in repression of methanation and the resulting fires and smoke on dump sites. Renerzyme has also been recorded effective in waste decomposition and odour control on waste management sites and dump sites. These microbes will assist in supplementing a biochemical pool of beneficial metabolites, offer a newer microflora and newer gas exchange kinetics.
1 – 2 % solution of RENERZYME is prepared in water. For this purpose, treated sewage water / seawater also can be used.
This above stated activity of Renerzyme and its mode of action was studied at Institute of Chemical Technology (Previously UDCT), Mumbai.
