Waste generation has increased in many sectors given the demand and population growth. Reverse logistics comes to contribute to the return of these wastes to the production chain. In this context, frying oil is one of the most processed waste and transformed into new products, such as: biofuel, boiler fuel, soap manufacturing, concrete formwork release agent etc. Oil is one of the wastes whose recycling only happens by law, because it has low added value, unlike plastic, aluminum and copper, whose values are higher. The average oil consumption in Brazil reaches 3 billion liters per year, but only 2.5% of this total is recycled, the others are discarded in the wild. The aim of this study is to analyze Reverse Logistics at different points, seeking to describe the chain steps, from the final consumer, through the PEV and ending in the companies that will reuse the frying oil already treated. In Manaus, the logistics of frying oil is done by cooperatives and private companies, being MASSEG, the largest company in the segment. This research has an explanatory character, approaching a case study, which made it possible to observe the financial and environmental feasibility of reverse logistics for the collection of frying oil, carried out at Condomínio Shopping Manauara Center, in the city of Manaus, AM. To reverse this scenario, many companies are investing in the reverse logistics process. Procedures such as leaving drums empty so that they are filled with waste oil, separation of solid waste and water from oil, are already part of the routine of tenants that also contribute to non contamination of water bodies. The collection, transportation, filtering, decantation and commercialization of the product already treated, for fuel purposes, is performed by the company itself. Finally, the company uses part of the treated oil to manufacture biodiesel, applied to the consumption of its own fleet, with no commercialization of the generated biodiesel. Thus there is a reduction in the use and costs with usual fuels (fossils), seeking to add the culture of sustainability.

This Paper present the steps to build an hydrogen cell emphasizing the need to use as a renewable energy source, being applied with internal combustion engines, as an efficient result obtained through electrolysis. Data presented in tables and graphs were collected and analyzed, both for urban streets and for highways. The tests in urban streets the vehicle presented 15.5 kilometers per liter of fuel (km/l), with efficiency of 38% compared to ordinary fuel, as well as on highways, made 18.9 km/l, with 33%, respectively acting at 60.5 kilometers per hour (km/h), the gain is due the fact that the system, which is directly linked to the generator currents and voltages consumption, implying that the higher current consumption, greater will be the gas generation. The results of the project show the veracity of achieving economy, yield and efficiency through hydrogen, allowing the possibility of implementation not only in vehicles but, in all varieties of engines available on the market today, and the substitution for other sources.
