DESCRIPTION
This presentation talks about how Sustainable Opportunities can be created in the Waste Management domain using bio degradable waste and plastic waste as raw material. This is, then, converted into Biogas and Plastic Diesel respectively, for which plant projections have been made at the XLRI campus, Jamshedpur. The inputs were given to us as a part of a BPlan competition - Genesis at Ensemble 2013.

Main Proposal
Aim: to ensure that XLRI can become self sustainable when it comes to waste management.
1. Bio Gas from the bio degradable waste such as food left-overs with organic fertilizers as the by-product targeted towards Bio diversity.
2. Plastic Diesel from the segregated plastic waste within the campus.
Generating:-
Bio Gas Proposition
• Ad hoc collection by two agencies. Overlapping areas of collection.
• Food waste from 4 messes goes to nearby piggery.
• All other waste is dumped into bin which is dumped into JUSCO dumping area.
• No value recovered from the different fractions.
• 808.5 kg bio-degradable waste generated everyday
Problem Statement: Waste

ARTI is a registered scientific society,established in April 1996 by a groupof scientists, technologists and socialworkers, led by Dr.A. D. Karve todevelop and transfer innovative,sustainable technologies to ruralpeople for income generation and toimprove their standard of living.
To date, ARTI has completed over 50 projects sponsored by various funding agencies - both national and international. It has emerged as one of the internationally acclaimed R & D institutions working in the field of rural development through innovative appropriate technologies.

A by-product of the decomposition of organic matter by anaerobic bacteria.
Clean and renewable energy easily replacing natural gas.
Replaces fossil fuels like LPG/wood fuel & reduces the emission of greenhouse gases contributing in carbon footprint reduction.
Setting-up of ARTI Biogas Plant (Dr. AnandKarve) which requires starchy food-stock like kitchen waste, left-over food, waste flour etc.
More efficient than cow dung based biogas plants – no foul smell & watery residue. The residue can also be utilised for biodiversity.
Why Biogas?
Environmental - Reduced carbon footprint, promoting renewable fuel, curtailing landfills
Financial - Reduced cost in cooking meals, savings on waste disposal
Societal - Healthier lives
Triple Bottom Line Analysis
Working Models
7 m3 ARTI biogas plant – customized solution A PVC Container – prerequisite fora bio gas plant
FinancialsOne Kg of Bio-Waste produces 100 Gm of LPG, i.e. 10 Kg of Bio-Waste produces 1 Kg of LPG or 800 Kg of Bio-Waste will produce 80 Kg of LPG
One Plant producing 2.5 Kg of LPG will cost about 2 lakh, so to produce 80 Kg of LPG we need 32 such plants, hence the costing is 64 Lakhs
LPG required per day – 9 * 19 KG = 171 Kg Bio Waste to Water required ratio = 1:2, i.e. for 800 Kg of Bio-Waste we need 1600 litre per day.
Annual gas consumption = 171 Kg*365 = 62415 KG Area Required = 200 sq/metre
1 Kg of LPG = RS 116 The conversion cycle is of Bio- Waste to Bio gas 2 days, i.e. we will install 2 plants which will cost another 64 lakhs.
Total amount spent on gas consumption = 62415 * 116 = 7240140
Percentage of Bio Gas consumption per day with respect to LPG consumed = 80/171*100 = 46%
Therefore, 46% of 7240140 = 3330464 saved per year
So, considering that there will be no increase in LPG price in next few years we will recover the total cost of plant in approx. 4 years
Financials
Plastic Diesel
• Extensive use everywhere and cant be discarded completely.
• Recycling is not a 100% solution due to irregular retrieval of bags from consumers.
• The need to tackle the inflated price of diesel by generating diesel through plastic.
• As efficient as petro diesel; used in machinery, heavy vehicles, generators.
• Technology is called Reverse Catalysation invented by Nilanchal Bhattacharya; patented in 2011 by IIP(Dehradun) Promoted by Green Earth Solutions (Manoj Sharma)
• No water required, no residual waste generated.
Why Plastic Diesel?
Environmental - Reduced carbon footprint, less health hazards for wildlife, promoting renewable fuel
Financial – Cheap alternative source of fuel, savings on waste disposal
Societal – scalable in terms of being implemented by using Self Help Groups (SHG)
Triple Bottom Line Analysis
Green Earth is a joint venture betweenScientist Mr. Nilachal Bhattacharya &Business Partner Mr. Manoj Sharma. Thefoundation has come up with a uniquetechnology that helps reclaim oil from wasteplastic. Truly, a breakthrough invention thatwill reduce plastic waste to such an extentthat it will make mother earth green again!
Green Earth is ready to deliver theconsumable oil to the human being by usingtheir patent innovative idea and they havegot success by producing 4 lit. oil from 4 kgwaste plastic material.

Inputs for Estimation
Source: Genesis 2013, XLRI
• Assumptions:-• 50gms of plastic per person/day• 1 hour power cut everyday• 500 kvA generator installed
• As per Green Earth Innovations:-• Plant capacity proposed = 100 kg• Plant cost = Rs 10 Lakhs
• Plastic to Diesel Conversion = 80%
• Total Diesel generated = 80% of 50 kg = 40 liters of Diesel/day
• Time Duration of Conversion = 6 hours
• Consumption of Diesel = 100 liters
• Contribution to the Diesel cost = 40%
TOTAL SAVINGS per year = 40 lt x Rs 55 x 300 days = Rs 6,60,000/-
Proposal for Plastic Diesel
Biogas
1. Preferred manual labor in preparation of slurry. A mechanical mixer can be used.
2. Generated biogas should be used daily. Provision to install a compressed bottling plant.
3. Consistency in raw material supply. Abundant supply available.
4. Disposal of waste. Watery in nature and acts as very good manure in biodiversity.
Plastic Diesel
1. Consistent plastic raw material. Overcome by storage facilities.
2. Picking & sorting of waste involved. Segregation at the point of generation.
3. PET & PVC plastic not preferred as it generates high fumes. Will be bailed & sold.
4. Inflammable in nature. Proper storage conditions and obtaining Explosives license.
