Three Problems One Solution: Waste and Emissions to LPG

There are three problems that are very common throughout almost the world, especially in developing countries that do not have sufficient energy sources of their own. These three problems are city waste that has not been resolved, emissions that have not been controlled and dependence on energy imports that must be subsidized, especially LPG which is needed for all levels of society, poor and rich, in villages and cities, throughout the world.

These three problems still haunt us today because there is no integrated solution. So this is the solution initiated by the R&D team from the Advanced Renewable Organization (ARO) for all inhabitants of the earth. Namely making all waste and emissions as energy sources, especially LPG - but LPG is short for Liquid Propane Gas, because this one is not from petroleum.

Solutions like this usually only stop at study, dissertation/thesis and finally go into a bookshelf. We hope that this solution will be different, we share the process here - so that it can be criticized and perfected by other experts, and in the end it will be useful for cleaning up the entire earth from waste and emissions, and becoming a solution for providing energy that no longer has to be imported from other countries.

In summary, from the process diagram and sketch below, we will know that processing waste and emissions into energy, especially LPG, is not as difficult as people think. With a little R&D work and several iterations of making a mini LPG reactor like the one in this sketch, any country will be able to greatly reduce its waste pile, reduce its CO emissions and at the same time walk the path to becoming energy independent.

We designed the reactor in this sketch to be sufficient to process around 24 tons of waste per day plus 24 tons of CO2 per day if needed as an option, and the output is around 5-7.5 tons of LPG per day. There is no need to build a large refinery with a capacity of thousands of tons per day, because it will not be efficient, transporting the waste to a centralized area will cost a lot of money and cause many social problems.

If waste has to be processed in another place (ex-situ) rather than at its place of origin (in-situ), such as to make it close to a source of CO2 emissions, then the waste needs to be carbonized into charcoal so that it is easy to store and transport and does not cause social problems.

Questions that often arise regarding this project are how much investment is worth, is this an economical project to undertake, etc. The simple answer is that the investment value of this project is approximately equivalent to the value of the LPG it produces in 1 year. It depends on how efficiently the operator manages other costs, but our estimate is that this project can payback in less than 3 years!
