less waste,
bigger impact


ORCA is an innovative food waste solution

Think of ORCA as a giant mechanical stomach. The ORCA technology simply mimics a natural digestion process using microorganisms to transform food waste into an environmentally-safe liquid. Unlike traditional food waste disposal where waste is transported off site to landfill, ORCA works on-site, delivering substantial benefits to the environment and your business.

how ORCA works

ORCA uses an aerobic digestion process along with microorganisms to transform food waste into an environmentally-friendly liquid that flows directly into existing plumbing on site.



the right ORCA for you

ORCA food waste digesters come in four different sizes. The right model for you will depend on how much
food waste you generate every day and how many hours a day you’ll be feeding the ORCA.

focused on taking down food waste

Food waste represents a substantial problem for both businesses and the Earth. Excess food waste hurts the bottom line of businesses and increases waste management costs, as well as attracting pests and odours as food waste sits in garbage bins between collections. Once that food waste reaches landfill, it decomposes, releasing methane gas into the atmosphere and leachate into the waterways.
