SLUDGE DISPOSAL

Sludge is the oily waste produced during a ship’s fuel purification process. It contains water, hydrocarbons, and heavy contaminants that can severely harm the marine environment if not properly handled. Safe and compliant removal is essential to protect oceans, ensure MARPOL and IMO compliance, and maintain operational safety onboard. Global Waste Management (GWM) provides licensed collection, transport, and treatment of sludge, guaranteeing environmentally responsible disposal and full regulatory compliance in every operation.

Leonardo Schunemann

CEO & OPERATIONS MANAGER

Leonardo Schunemann is a dedicated husband and father of three, and a business leader whose career is marked by purpose, integrity, and an unwavering commitment to results. Over the years, he built a solid professional foundation working in multiple third-party companies, including serving as a partner, where he refined his expertise in business development, commercial strategy, client acquisition, and the management of high-value, long-term relationships. This experience shaped his vision of entrepreneurship based on ethics, transparency, and operational excellence.

Guided by this vision, Leonardo founded GWM, a company fully dedicated to ship waste collection and environmental services.

Its growth is anchored in credibility earned through consistent performance, respect for regulations, and a relentless commitment to delivering high-quality services.

Under Leonardo’s leadership, GWM has achieved significant market recognition. The company serves more than fifty shipowners and maintains daily operations across Brazil’s main ports, offering reliable solutions that meet the industry’s highest standards.

He approaches each partnership as an opportunity to create mutual value and to contribute positively to the maritime sector. Through his leadership, GWM aims not only to deliver outstanding operational results, but also to become a national benchmark in environmental responsibility, service quality, and purposeful management.
