E#hashtagnergy Efficient Method for Recovering Oil from Asphalt Waste utilizing Bioremediation. US Patent No. 10,550,329 B2. Awarded on 4h February 2020 Waste asphalt is generated globally every time a road is built or re-layed. Some countries dump the waste with other solid waste even though it is not biodegradable. In the USA, more than 75 million tons of waste asphalt is generated annually and much of it is re-used by mixing the waste with a new binder and used on the roads once again. In Europe, this practice is not acceptable. They pile up the waste in isolated spots. There is no acceptable method for recycling waste. The current patent describes a process for recycling asphalt waste without the use of extreme heat needed in the current practices. The method is based on a combination of bioremediation product VaporRemed and a chemical accelerator to produce # 4 fuel oil. The fuel is an additional source for revenue and the process can be scaled up to meet large volumes of waste. The process can also be used for producing fuel oil from Oil sands in Canada and elsewhere in an environment-friendly and cost-effective manner.
