sunshaker Posted August 18, 2015 Share Posted August 18, 2015 (edited) Not new news, but first time I have seen this process. http://www.sciencealert.com/holy-crap-watch-this-guy-turn-plastic-back-into-oil Japanese man takes plastic containers, bottles and bags, shoves them all in a machine and then, hey presto, out comes diesel, kerosene and gasoline. It looks so easy it makes you wonder why we're not doing this all the time. Well, there's a reason for that - the process is known as anhydrous pyrolysis, and despite how simple it looks, it's unfortunately not considered very effective because it uses up a lot more energy than it creates. Surely this can be adapted to work with another process that has waste heat energy, maybe somewhere like a foundry that as a lot of waste heat energy that could perhaps be adapted to use this tech? maybe even incorporated into https://en.wikipedia.org/wiki/Waste-to-energy_plant Edit: Exciting breakthrough as Indian scientists 'turn plastic into petrol and diesel'Read more: http://www.dailymail.co.uk/indiahome/indianews/article-2727285/Waste-not-want-not-New-technology-turn-plastic-petrol-diesel.html#ixzz3jAV3C4cK http://www.dailymail.co.uk/indiahome/indianews/article-2727285/Waste-not-want-not-New-technology-turn-plastic-petrol-diesel.html I believe anything like this is going to be good for the environment, We all hear of the amount of plastics in the ocean that enters the food chain. Most of these plastics are from accidents in transport from country to country. http://www.theguardian.com/vital-signs/2015/feb/12/science-plastic-oceans-study-fish-pollution-worse next decade our ocean will hold about one kilogram of plastic for every three kilograms of fish Edited August 18, 2015 by sunshaker Link to comment Share on other sites More sharing options...

Perhaps a solar oven. A few years ago I built a small model of a parabolic trough oven to experiment with making bio-char. At ~4ft across the highest temp I reached in the receiver was just over 200ºF and a good deal short of the ~500ºF I needed. Not sure how it would have to scale up to reach the temps the guy's process needs. My model: 1 Link to comment Share on other sites More sharing options...
sunshaker Posted August 19, 2015 Author Share Posted August 19, 2015 Perhaps a solar oven. A few years ago I built a small model of a parabolic trough oven to experiment with making bio-char.

Not sure how it would have to scale up to reach the temps the guy's process needs. My model: It seems a good idea if it can be scaled up to reach 350celsius, I had a look and some parabolic systems can reach into the thousands of degrees celsius. I looked for solar furnaces but they seem to be mainly for heating homes, I did find these solar ovens that look look they could possibly be adapted http://gosunstove.com/collections/solar-ovens/products/gosun-mini Dry Weight: 1.5 lbs (0.7kg)Oven Volume: 9.5oz (0.3L) of food Oven Dimensions: 1.75”(4.5cm) outside diameter, 1.25”(3.2cm) inside diameter, 11.5” (30cm) length Unit Assembled Size: 12.5”(32cm) long x 6”(15cm) tall x 8”(20cm) wide Maximum Temperature: 700°F (371°C) Working Temperature: 200°F (93°C) - 550°F (288°C) Cooking Time: As fast as 10 minutes! This electrical home made arc furnace also looks pretty cool http://lifehacker.com/build-a-homemade-electrical-arc-furnace-with-lantern-ba-1691381102 It would be cool to produce your own fuel from waste plastics+solar energy.
