Waste Industries LLC, a Raleigh-based company that does curbside trash pickup in Durham County, North Carolina, is spending about USD 8 million on a project to launch a new fleet of garbage trucks that run on compressed natural gas (CNG). The company is updating its fleet with 19 garbage trucks and one service truck and will construct a private refuelling station for the trucks, reports the Herald Sun. Lower emissions, reduced maintenance costs and lower fuel costs will help offset the additional cost of purchasing alternative fuel trucks.
