Dishwashers Prove More Eco-Friendly Than Hand Washing, Study Finds

By MGN Editorial•March 6, 2026 at 03:12 PM

A new study from the University of Michigan finds that using a dishwasher can be more sustainable than hand washing dishes, especially when using the right detergent.

In a surprising finding for the maritime industry, a recent study from the University of Michigan has concluded that using a dishwasher can be more environmentally friendly than hand washing dishes. The study, reported by PR Newswire, found that dishwashers can save both water and time compared to hand washing. 'Washing Dishes By Hand Can Be More Expensive and Environmentally Unfriendly Than a Dishwasher,' the report states. 'Using the Right Detergent Increases the Sustainability Even Further.' Researchers examined the water and energy usage of hand washing versus using a dishwasher, taking into account factors like the type of detergent used. They found that modern, energy-efficient dishwashers can significantly reduce water and electricity consumption compared to the common practice of hand washing. 'A recent study from the University of Michigan found there are pros and cons to both hand washing and using a dishwasher,' the report explains. 'However, when you factor in water and energy usage, as well as time spent, a dishwasher often comes out ahead in terms of sustainability.' The findings could have implications for the maritime industry, where crew often hand wash dishes due to the limitations of onboard facilities. Encouraging the use of energy-efficient dishwashers, where feasible, could help reduce the environmental impact of maritime operations. 'Using the Right Detergent Increases the Sustainability Even Further,' the report notes, suggesting that the choice of dishwasher detergent is also an important consideration for maximizing the eco-friendly benefits. Overall, this study provides useful data that shipowners and operators should consider as they look to improve the sustainability of their onboard processes and reduce their environmental footprint.
