N.H. may modify C&D fines ban.The New Hampshire New Hampshire, one of the New England states of the NE United States. It is bordered by Massachusetts (S), Vermont, with the Connecticut R. forming the boundary (W), the Canadian province of Quebec (NW), and Maine and a short strip of the Atlantic Ocean (E). Department of Environmental Services (DES) is looking at several formula options presented by members of the Construction Materials Recycling Association (CMRA CMRA Commercial Mail Receiving Agency CMRA Construction Materials Recycling Association CMRA Central Motorcycle Roadracing Association CMRA Capital Market Risk Advisors, Inc. ) as a response to the agency's recent ban on the use of C&D fines as alternative daily cover (ADC (1) See A/D converter.

For other uses, see Municipal waste (disambiguation). Municipal solid waste (MSW) is a waste type that includes predominantly household waste (domestic waste) with sometimes the addition of commercial wastes collected by a (MSW (MicroSoft Word) See Microsoft Word. ) landfills. The ban was instigated because the fines were being pointed to as the cause of hydrogen sulfide hydrogen sulfide, chemical compound, H2S, a colorless, extremely poisonous gas that has a very disagreeable odor, much like that of rotten eggs. It is slightly soluble in water and is soluble in carbon disulfide. odors at some landfills. The CMRA, through its New England chapter management at Green Seal Environmental, worked with member companies LL&S and ERRCO Recycling to develop alternative fines formulations that could be used in MSW landfills without adverse reaction. LL&S, based in Salem, N.H., used 30-cubic-yard rolloffs to simulate conditions in a landfill to try out various formulations of the fines, i.e., fines alone, fines mixed with coal ash, fines mixed with sand, etc., to see if odors would be created. The preliminary results were presented at an October meeting of the DES C&D Fines Workgroup. The work group is made up of C&D recyclers, landfill operators, DES officials, academia and the CMRA. The preliminary results showed that a mixture of virgin soil, C&D fines and coal ash mixed in a 1:1:1 ratio created little if any hydrogen sulfide odor. The fines came from a process that used the best management practice of kick-sorting all incoming gypsum out of the C&D recycling facility. Other mixtures also showed promise and were to be further explored. In addition, DES was investigating some other uses for the fines, such as a fill material. DES personnel promised that the agency would take quick action on deciding which option could start being used as soon as possible, as the fines material was stacking up on recyclers' sites. |
