LYNDONVILLE — The Northeast Kingdom Waste Management District’s Board of Supervisors heard about the new foam recycling program during its August meeting. The district is taking advantage of a 6-month free trial to try out a foam densifier unit. The staff was trained last Friday on how to use the unit. Recycling of expanded polystyrene, which is commonly known by a trademarked brand name of Styrofoam, began last Saturday at the NEKWMD’s Lyndonville site. If, after the trial period, the district wants to buy the unit, it costs about $50,000 and there are grants that the staff already is planning to seek to help defray the cost of the investment.
