Marine Composting Toilet

Marine composting toilets provide an economical sanitary solution on board a boat. Odourless operation is ensured by a 12 V fan running all the time. Marine composting toilet in this section are compact as possible as space is at a premium in either motor homes or on board a boat. Traditional flush toilets use a lot of water and require a large tank below deck. This tank needs to be emptied at pump-out stations which can be expensive and in inconvenient locations. A marine composting toilet on the other hand is totally self contained with no need for a tank below the deck or any water supply. Chemical toilets are inconvenient in the long run and raise environmental concerns. A marine composting toilet uses no chemical and facilitates natural microbes to break down the waste into safe composted material.
