Empirical Validation of the Use of Recycled Lubricant Oils to Make High Energy ANFO Type Blasting Agents

As per the report, global industrial explosives market was valued at $7.1 billion in 2019, and is expected to reach $10.9 billion by 2027 with growing at a CAGR of 5.5% from 2020 to 2027. Globally, ammonium nitrate Fuel oil (ANFO) explosive contributed more than half of industrial market share owing to its stability, ease of handling. Metal mining sector in India requires a significant share of ammonium nitrate fuel oil (ANFO) as Explosive to remove large amount of overburden materials and metallic ore including top surface soil and debris. Diesel oil which is commonly used fuel phase to prepare ANFO consists of 5.7% by weight in the mixture which impacts the overall cost of the ANFO explosive considerably. With the developed ANFO product, at least 50% of the explosive cost will be reduced which will be highly beneficial of the economic growth of the mines. In addition, with this developed product ahazardous environmental pollutant material, waste lubricant oil was easily and successfully recycled in a form of renewable energy sources in a sustainable manner.

ANFRO product i.e. use of Ammonium nitrate (AN) and recycled lubricant oil (RLO's) with Fuel (diesel) oil in appropriate mixture as developed will be used in all the open pit mines of India. The cement industries, stone quarries owners and companies dealing in civil infrastructure will be more beneficial by using the developed product.

• Reduced ~50% of the overall cost of the explosive used for the blasting operations.
• Most importantly, with this developed product, hazardous environmental pollutant material i.e. waste lubricant oil wassuccessfully recycled in a form of commercially significant renewable energy sources in aeco-sustainable manner.
• With the use of the developed product, overall consumption of an important and limited fuel (i.e. diesel oil) can be significantly reduced, which is extremely beneficial for future of our society.
