The three-year contract starts this month and comprises commercial waste minimisation, collection and recycling, plus site clearance services, at the Port of Poole.
A team of 12 Waste Services staff will collect commercial waste and recyclables from the ports most heavily used public areas on a daily cycle.
Waste Services business manager Paula Sinclair said: Our first three-year contract with the Commissioners saw us deal with all sorts of every day and unusual waste materials.
We were even called out to remove a dismantled walk in fridge, abandoned cars and boats. No two days are the same, which makes it interesting for the team, and so were delighted to renew our business relationship.
Waste Services will collect waste, created by ships as well as portside activities, such as general ship garbage, cruise liner waste, international catering waste shellfish waste and paint scrapings. Liquid and hazardous materials such as oils and recyclables such as scrap metal will also be retained.
Poole Habour Commissioners Sally Porter said: The Commissioners have a publicly-available waste management plan in line with its entrusted duty to conserve and improve the harbour environment.
