Washing hands vs. Dishwasher
Studies conclude that dishwashers are better for the environment than washing up by hand.
Overall using a dishwasher results in lower carbon emissions, even if you add in its embodied emissions. Handwashing generally uses more water than dishwashers, resulting in more greenhouse gas emissions from distribution, and more energy use from heating up the water.
If handwashing is the method of cleaning currently at your venue, speak to your GM or Line manager about the impact this has on water usage. PLUS - when using dishwashers make sure they are alwasy packed full when turned on to save on the amount of loads!
