Cost benefit study: Waste

Measuring to manage: Waste at Gunwharf Quays, a mixed-use development on Portsmouth Harbour, owned by Land Securities.
The 33-acre site houses designer outlets, bars and restaurants, a cinema, a bowling complex, a comedy club, a casino, a Health & Fitness Club and a hotel. In addition there are over 300 homes on site and near 2000m2 of office space. 
 
Gunwharf Quays Management Ltd. actively promotes sustainable resource management and acts as a waste broker for all occupants, managing nearly 3,000 tonnes of mixed commercial and municipal waste per annum. In 2010 the company recycled about 55% of its waste with the remainder being used in a energy recovery facility to produce electricity, therefore achieving nearly 100% recovery of resources.
 
The company is striving for further waste minimisation and to increase re-use of materials by for example replacing card board boxes with tote boxes and replacing disposable products with recyclable alternatives. These efforts are aimed at reducing waste at source and understanding and changing processes to enjoy the environmental and business benefits of waste and cost savings.
