About 50 jobs will be created during construction and there will around 13 staff in the long-term, including truck drivers. There will be an average 21 HGV movements a day to the site each way, according to the planning documents which states the extra traffic "will not have a detrimental effect on the local highway network". The electricity generated from anaerobic digestion will be used to power the facility. Any remaining energy will be supplied to Welsh Water's neighbouring plant. "It will mean Welsh Water's largest works will become largely self-sufficient," Mr Hall added. The process will also generate a high nutrient fertiliser and soil conditioner, most likely to be used by farms in the Vale of Glamorgan. The Cardiff Organic Waste Treatment Project contract will be awarded in early 2014. If successful, Kelda says it will start construction in the middle of next year and start operating in early 2016. The other shortlisted bidders are Agrivert Limited, GENeco and Shanks Waste Management Ltd.
