Alternative wastewater disposal systems reduce groundwater pollution by decomposing organic wastes or removing nutrients more effectively. Hand dryers reduce water and paper towel use, alternative treatments for cooling tower water reduce chemical use, and carpet tile allows modular replacement of worn areas. In screening products for this area, we focus on quantifiable environmental benefits and strong performance records.
Waste XPress pulper systems from InSinkErator grind commercial kitchen waste and then separate the water from the solids, allowing the relatively dry pulp to be collected for landfill disposal or composting. InSinkErator claims the unit reduces kitchen-waste volume by 85%. The systems are designed to fit beneath a typical dish table in a commercial or institutional kitchen.
Unlike some other pulper systems, Waste Xpress is not designed to connect directly to a composting or biogas unit; the waste needs to be hauled by hand. And although InSinkErator touts the unit's ability to grind jelly packets and other items, these should not be used in the system if the waste will be composted. Policies should be employed to use only organic materials, and signage should be used to help keep non-compostable plastics and other materials out of the waste stream.
Enabling commercial, public, and apartment building and campus occupants to be good environmental stewards is important. Systems that make it easy to recycle wastes should be provided in offices, institutions, apartment buildings, and other public spaces.
