bearnard55 Posted April 1, 2021 Report Posted April 1, 2021 Have you heard about the new special type of rocket fuel that is made from plastic waste? One company uses particular kinds of plastic to remake them in rocket fuel OceanBreeze 1 Quote
HallsofIvy Posted May 11, 2021 Report Posted May 11, 2021 The problem is energy! In order to be useful as fuel, a chemical has to have energy contained in through the way the atoms are put together. Plastic, while made of complicated molecules, doesn't have much energy stored in it. Quote

Presently, there is a great deal of research being carried out in plastic-to-energy technology. According to this source: “The molecules that make up plastic products are a powerful source of energy. For example, in a facility that converts waste into energy, non-recycled plastics can supply more than 15,000 BTUs per pound. That’s more energy per pound than any type of coal” Quote

The result of the test has shown that it`s 1% - 3% better than kerosene by its energy characteristics. But I am not sure if it`s possible to use the new rocket fuel in long space journeys.

bearnard55 Posted May 14, 2021 Author Report Posted May 14, 2021 (edited) However, there is a problem, the alternative rocket fuel also called as a green fuel can be remade only from particular types of plastic.The following types of plastic can be converted into ecosene fuel: Polypropylene (PP). Polyester (PE). Polystyrene (PS) and their mixtures and analogs Edited May 14, 2021 by bearnard55 Quote
bearnard55 Posted May 18, 2021 Author Report Posted May 18, 2021 (edited) But still, I guess this rocket fuel is a great invention for humans. I assume it`s not really effective for some long space journeys but still, it can be used for some small launches for microgravity missions and experiments. https://www.skyrora.com/ecosene Edited May 18, 2021 by bearnard55 SpaceTourist33 1 Quote
SpaceTourist33 Posted May 20, 2021 Report Posted May 20, 2021 As I understand, this fuel can't be used for long spaceflights, right? So engineers need to modernize this fuel to make it suitable for interplanetary flights. bearnard55 1 Quote

But still, this type of fuel can be used for some small launches which are aimed at some microgravity mission and experiments without any modernization. SpaceTourist33 1 Quote

Taking into account how many small launches occur every month (remember SpaceX tests alone), using an eco-fuel is a good step towards cleaner environment. bearnard55 1 Quote

Yeah, many launches are made like test launches or delivering microsats into orbit by different space agencies. So it would be a great idea to use eco-fuel in the launches I`ve mentioned SpaceTourist33 1 Quote
