Bean's Commercial Grease Incorporated has provided a storage drum for the cooking oil, which will be taken to Bean's New England facility to be refined for reuse.

Paint?

OIL  based paint is a hazardous waste and must be disposed of accordingly.  Twice a year the City of Portsmouth provides hazardous waste disposal services, via Household Hazardous Waste Collection (click here) for more information on hazardous waste and the next collection date.

Latex paint, once dried, is not considered a hazardous waste.  However, if the paint is not solid all the way through it can leach posing a threat to the landfill and/or ground water and therefore as a liquid it is considered a hazardous waste.  In order to dispose of latex paint in an environmentally compliant manner pour the latex paint into either saw dust or kitty litter.  Allow the mixture to dry (increase air flow to expedite this process).  Once the mixture is solid, it may be brought in to the Recycling Center.  The empty and dried paint cans may be recycled.
