Skyrora is working on alternative processing and innovative plastic recycling method with using a catalytic pyrolysis method to obtain new sources of energy and high quality fuels for aerospace industry.
Ecosene is a high-quality eco-aviation fuel that we are looking to produce from waste plastic obtained from local councils. The plastic will be subjected to three processes – pyrolysis, refining and blending with aviation-fuel-required additives and inhibitors. Pyrolysis is a low temperature thermal degradation process which converts the plastic chips into a low grade eco-fuel. A refining stage then subjects the pyrolysis fuel product to further processing in order to ensure the fuel composition lies within the desired range for aviation fuel.
This includes hydrocarbon chain lengths typically between C12 – C15 and the presence of aromatic and (saturated) olefinic hydrocarbons. The refining stage of Ecosene production ensures that the fuel has the density, molecular weight, viscosity and aromatic content legally required for aviation fuel.
Jet fuel is based on either unleaded kerosene (Jet A/Jet A-1) or naphtha-kerosene (Jet B). Jet A-1 fuel is purely kerosene based and powers commercial aircraft, whereas Jet B fuel is a kerosene-gasoline mix. Jet A-1 is the required standard of aviation fuel for the majority of the world.
Jet A fuel is most commonly used in the USA and legally must have a freeze point of -40 °C, whereas in Europe, Africa, Australasia and the Middle East, Jet A-1 fuel is required and must have a freeze point of -47 °C. Jet A-1 fuel is also subjected to stricter blending regulations – an example of this is the addition of static dissipater additives which prevent static charge build-up in the fuel.
The production processes researched within this report aim to process synthetic Rocket Propellant-1 fuel (RP-1) which must meet, and exceed, the standards of aviation fuel Jet A-1.
We have the opportunity to be the front runners in the production of an eco-fuel which exceeds the standards of Jet A-1 fuel. With an increasing need to manage global waste as well as a growing demand for fuel (leading to a significant reduction in fossil fuels), the production of Ecosene has the opportunity to change the operation of the aviation industry (and many others) in years to come. In addition to this, we have the opportunity to reduce the transportation footprint of aviation fuel by developing a container/skid-based Ecosene process.
The skid will allow small aviation companies to produce their own fuel on site thus reducing airports/airlines fuel transportation costs and environmental footprint whist improving their fuel availability.
Recycling is emerging as a sizeable industrial sector which creates employment, reduces economic waste and improves the environment. Increasing domestic re-cycling capability will reduce the cost and sometimes irresponsible export of waste to overseas locations where capacity is lower and environmental standards are inferior.
The world suffers from an acute lack of infrastructure that can process plastic waste. The majority of polystyrene waste currently ends up in landfill. We remove the problem of finding somehere for plastic waste disposal by offering a new method of reusing it, reducing the reliance on finite fossil fuels and loweringcarbon emissions, whilst providing a high-grade quality fuel alternative to a growing market.
Across the world, pollution caused by plastic waste is a critical problem. It was recently estimated that 8 million tonnes of plastic end up in the oceans each year. By 2025, the annual global cumulative output of plastic waste into our oceans will have exceeded 155 million metric tonnes, and global municipal waste generation will reach 2.2 billion tonnes per year. Environmental concerns regarding plastic waste have risen greatly.
