FREQUENTLY ASKED QUESTIONS

1. What are the preferred feedstock for your plant?

2. What is the conversation ratio for different plastic feedstock? What are the best plastic type's feedstock for your process?

• Conversion ratio is input specific. HDPE, LDPE, PP will yield highest yields of app 1 kg to 1.1 liters. Other plastics will have reduced yields and may yield app 800 ml per kg. PET is not to be used in our process as PET will have a higher commercial value as a recyclable material. PVC will have the lowest yield of app. 300 ml per kg. Yield from the other feedstock can be intimated on request.

3. What kind of yields can we expect from processing waste plastics with your unit?

• 1.1 liter of fuels per Kg of plastic (25 ton X 1000 = 25000 Kg x 1.1 = 27,500 liters / day).

28. Is further processing necessary?

• Yes (further refined to convert it to petrol, kerosene, diesel and light diesel oil). The fuel output as it is, can be used for stationery engines and in case the same has to be converted to motor fuels then additional equipment is required, viz., Distillation column and de—sulphurization unit.

35. What are warrantiesl guaranties on parts used in plant?

• We offer warranties on workmanship, free replacement of defective parts for a period of one year. Our on—site supervisors will operate the plant for a period of 3 months at your location and will hand over the plant to you. During this period, The plant capacities will be proved and plant parameters adjusted to maximize Yield from your input material.

36. How hard is it to operate the unit and are they maintenance intensive?

• The plant requires regular maintenance and the plant needs a shutdown to Clean reactors once a month. The catalytic convertors are outside the process Reactors and the catalyst changes have to be made as and when the catalyst is poisoned. The catalyst change does not require shut down of the reactors and the catalyst can be changed while the process is on. Regular maintenance ofall moving parts is as per a schedule of maintenance. The plant has very few moving parts and hence it is not maintenance intensive.

37. After order what is the delivery period/schedule of unit?

• Six months. The unit is prefabricated, assembled and tested prior to shipment and hence minimum time is required for erection and commissioning. The product will start coming out within first hour of operation.Delivery is 4 months from receipt of payments.

38. What are the guaranties for production of plant?

• 25,000 liters of petroleum / day, based on the feedstock. The product output depends upon the quality of the input. Maximum output is achievable if HDPE, LDPE, PP type of plastics are used as feedstock. Mixed plastics input will reduce output based on the type of polymer being processed.

• Engineers and Operators will be provided on site training for a period of3 months. Operations manuals, maintenance manuals, safety manuals will be supplied along with the plant.

40. What level of automation we expect?

• The plant is automated. There is a high level of automation with process Controllers controlling the operations.

41. How many days of feed stock needed in back stock?

• It is advisable to have 7 days stock

42. What are the environmental requirements for permits and licenses (EPA)?

• Closed loop system so that the emission parameters are met easily,

• No air, water or other pollution ~ zero discharge system

43. What other licenses required from federal, state, county and city authorities?

• The requirements are site specific and location specific. Local requirements must be studied and permits obtained as per the requirement.

44. Does Polycrack system accepts PVC?

• The process can tolerate up to 5% PVC as it is in the feedstock.

45. What are the Polycrack advantages in comparison to the other technologies?

• One area where most of the p|astic—to-fuel technologies fail is the quality of fuel produced. All such technologies use a catalyst, typically metallic oxides or aluminum silicate compounds, to convert the plastic to fuel. However, the fuel produced has a high trace of catalyst, almost 2% to 5% residue (app 500 Kg to 1250 Kg) in a 25 ton-per—day plant. Accordingly this high volume of residue created was one reason why most plastic-to—fue| conversion plants do not get environmental clearances, because residue has to be disposed.

• Our process leaves no catalyst in the residues. The residue is free carbon that can be compressed into pellets and used as fuel in furnaces. A plant with capacity of 25 tons a day using our technology would typically produce residue of about 1 ton of free flowing carbon powder which has commercial value. In other words it is a zero discharge process.

• Our process can handle moist, dirty plastic, mixed plastics and industrial plastics including automobile fluff.

• Our process can handle mixed feedstock like plastic along with biomass, waste oil, refinery sludge etc.

• We can practically run all kinds of plastics including the metalized ones, plastics backed with aluminum foils, packaging, tetrapacks etc. The yields however will vary depending upon the polymer content in the input material.

• Presence of metals, glass, fiber, wire, cable, organic, inorganic, TiO2 fillers etc., does not impact the process in anyway.
