I buy all of my perishable items - like coffee, tea, shampoo, conditioner, etc. - in bulk from local suppliers to minimize waste and support the community. Plus it makes it much easier for my cleaners as they can simply refill the items when they are running low.
I also supply a mesh tote bag and reusable grocery bags so guests don't have to take the plastic bags at the grocery store when they go shopping.
I also use a coconut sponge instead of a plastic scrubber, and all of my shampoo, conditioner, dish soap, dishwasher detergent is made from sustainable ingredients.
I also supply water bottles guests can use during their stay to pack water/drinks when they go on outings to avoid the need to buy plastic bottles.
