HCFC Consumption scenario<br />Year<br /><ul><li>Presence of large number of Small and Medium Enterprises in the Sector</li></li></ul><li>In India, today HCFCs are being used by more than 450 units as blowing agent in processing of PU Foams. Majority of which are SMEs.<br />
CONSIDERATIONS FOR SELECTION OF ALTERNATE TECHNOLOGIES<br />
India has large number of small and medium size enterprises, quite often located in crowded areas. It is very important that an option selected should cater the need of SME sector. <br /><ul><li>HFCs can be used in combination with other blowing agents which can give good balance of foam Performance, cost and energy efficiency. </li></li></ul><li>CURRENT AVAILABLE ALTERNATIVES<br />Most promising alternative technologies for Indian Foam Sector are<br />
Technical Options Under Trial in Some Countries<br />Note: These alternatives are not yet technically proven and their environmental benignness and economical viability is yet to be established.<br />
SITUATION AFTER CFC PHASE OUT<br />CFC Phase out was started in 90’s, change over decision by Indian Foam Industries was relatively simple, as selection had to be made from three alternative blowing agents which were well established in developed country and could easily be adopted by Indian Foam Sector. <br />These were:-<br />14<br />
<ul><li>Now that the dates are advanced to 2030, there is a big challenge for Indian Foam Sector as no technically proven and economically viable solutions are available to phase out HCFC 141b considering the fact that most HCFC 141b users are SMEs including few large enterprises as well.</li></ul>15<br />HCFC Phase Out :Present Scenario<br />
Integral skin</li></ul>It is the Rigids, Integral skin & some flexible slab stock foam applications where HCFC’s are being used. In this sector phase out program requires a careful approach<br />17<br />
HCFC Phase Out Approach<br /><ul><li>Complete change over to long term blowing agent for large enterprises.
Partial production can be changed to alternate blowing agent where HCFC 141b can be phased out stepwise over a period of time.
Use reduced HCFC 141b systems where mixture of HCFC 141b with other alternate blowing agents may be used, which can allow cut down of HCFC 141b phase wise and this solution can be adopted for SMEs.</li></ul>The right approach for phase out of HCFC 141b from Indian foam sector can be as above<br />
<ul><li>While selecting an alternate blowing agent, safety and fire hazards must be given due considerations as some of the blowing agents are highly combustible / explosive and as such can be difficult to handle by small enterprises.
Energy should be most important factor particularly for rigid foams which are mainly used for insulation applications. </li></ul>19<br />Safety and Energy Concerns<br />
HCFC Phase Out - Challenges<br /><ul><li>Actual consumption of HCFC is nearly 4 times higher than the CFC consumption base line. This implies-more investments and phase out interventions.
Another barrier that HCFC using enterprises possesses manufacturing equipments that are far from the end of product life.
Working on adoption, evolution & costing of new technology.
Evolution of all HCFC phase out options in light of safety and environmental consideration.
Need to determine optimum management modality and funding arrangements</li></ul>20<br />
<ul><li>SMEs are the backbone of Indian economy.
The Polyurethane foam sector, SMEs consists of 91% of the total Foam Industry.
Presently available alternates are mainly HFCs, such as 245FA, 134 A, 365FA and Hydro Carbons(Pentanes)
Hydrocarbons are highly inflammable and it is not feasible to use them in pre blended Polyols which is widely used by SMEs</li></li></ul><li>The Polyurethane Foam Industry is open for a Dialog with its counterpart Industry world over to understand about the low GWP alternatives, including their Economical & Technical viability and the time frame for its availability.<br />
