Abstract:
The revolution of industries provided the increase and speed of productions, mainly the production of steel [1]. In the specific context of shipbuilding, the use of steel plays a fundamental role in the design of vessels. Despite being a 100% recyclable material [2], there are few incentives for this practice in the sector. This is due to the predominant linear production model, where waste is still seen as a worthless by-product that cannot be reused. In this sense, the use of steel from scrap recycling, inserting it in the construction phase of vessels, emerges as one of the ways to promote the circular economy and guide the adoption of good construction practices for this sector. This paper intends to identify Transpetro's fleet of oil tankers and estimate the total steel demand for the construction of Suezmax class oil tankers. Based on the data collected, an analysis was made of the possible impacts caused if this fleet were built exclusively with recycled steel[3]. The article discusses if Transpetro [4] has any decommissioning fund and/or sustainable decommissioning planning, aiming to guarantee the reinsertion of the steel from these vessels in a new production cycle. It also discusses fiscal policies [5] that encourage the reinsertion of steel in the shipbuilding chain and how legislation has cooperated or delayed circularity actions in the sector. We will see that by incorporating circularity practices in this industry it will be possible to dissociate the construction process from the practice of extraction of new natural resources, resulting in the reduction of operational costs, promotion of the ship steel recycling market, and the environmentally correct disposal of this waste. Contributing significantly to the preservation of the environment and the reduction of Greenhouse Gas (GHG) emissions.
