Short Description

Hart District Council is a waste collection authority situated in the north-west corner of Hampshire. It is home to approximately 88,800 residents, and collects waste and recyclables from all of its 36,360 domestic properties. Its recycling and composting rate in 2008/09 was 39%. It is classified by the Office for National Statistics as a “Prospering Southern England” area. The Council provides an in-house alternate weekly collection of refuse and dry recyclables. A two-stream dry recyclables collection is also provided. Paper, cardboard, cans and plastic bottles are collected co-mingled from a 240-litre wheeled bin, and colour-mixed glass bottles and jars are collected from a 40-litre kerbside box. The council also offers a fortnightly subscription-based garden waste collection service.

Glass collections were first introduced by Hart District Council in January 2004, as a joint trial of 5,000 households, involving both Hart District Council and neighbouring Rushmoor Borough Council. A decision was made not to colour-separate the glass when loading onto the recycling vehicles as a calculation of the potential costs showed that this would be the cheapest collection method. A reprocessor was contracted who would accept the glass colour-mixed and would still ensure the glass would be fed into the re-melt industry. In 2006 glass collections were rolled out across the district and, as the chosen collection method proved efficient and cost-effective, this arrangement remained.

Collection crews empty glass from the kerbside boxes into 240-litre slave bins on the lorries before discharging it into the single compartment collection vehicle. Once collected, the glass is taken to Chineham Transfer Station and bulked by Veolia, before being delivered to Recresco in Southampton. Here it is cleaned and colour separated, then sent to Quinn Glass (a glass manufacturer) where it is recycled into new glass packaging for food and beverages.

The Council collected 2,364 tonnes of glass from the kerbside in 2008/09, amounting to around 65 kg per household, putting it in the upper quartile of performance for this authority. This resulted in a saving of 742 tonnes of CO2 emissions. This CO2 saving is one of the major advantages of sending glass back into the re-melt industry, particularly in comparison to sending glass to aggregates, where it has a negligible CO2 saving.
