Additionally, this is wasteful and can be costly for the company. To solve this problem, the ,flow-back fluid, can be recycled on site to be used another time [8]. This has the benefit of cutting the cost of disposal and of obtaining ,fluids, needed for new fracking jobs, as well as improving the company’s public image.
