Waste

Waste Collections

The Union use the College’s system of colour-coded and labelled bins in its offices and other areas.

 

What goes in each bin?

  • Green - Dry mixed recycling - glass, cans, tins, hard plastics
  • Red - Glass - domestic
  • Blue - Paper and card
  • Black - General waste

 

1. General waste

General waste is collected by the cleaning contractors for the office spaces, collections in the bars areas are conducted by the bar teams.

Both teams use the waste bins in either the Beit Quad or in the Sherfeild building. It is collected on a daily basis and taken to an Energy from Waste Plant called SELCHP (South East London Combined Heat and Power) in South Bermondsey, South London. The waste is burnt and steam produced. Energy is recovered from this process and sent to the National Grid in the form of electricity.

 

2. Recycling

Recycling is collected by the cleaning contractors who use the waste bins in either the Beit Quad or in the Sherfeild building.

2.1  Paper goes directly to a paper mill from the contractor where it is pulped and turned into other paper materials.

2.2  Glass is taken directly to Day Aggregates where it is crushed and used in road manufacture. This material is known as glassphalt.

2.3  Mixed recycling is taken to a Materials Recovery Facility (MRF) where the waste is sorted and separated and then sent off to various re-processors where they are made into other recyclable materials. The recycling goes to either Veolia’s MRF in Southwark or Greenwich.

2.4  For printer cartridges Imperial College use a contractor that collects printer cartridges that are taken to a central depot and reused as new printer cartridges. If the cartridge cannot be reused then it will be recycled. The company that do this are called Office Green. They support a number of charities. See the webpage for more details. http://www.officegreen.co.uk/supported-charities/default.aspx

There are two central points where printer cartridges can be deposited across campus and there is one of these in the Beit Quad Union. This is located on level 2 in the reception area of the Union.

In 2013 the Union trialed using the colour coded bins in the public spaces of the bars, however due to the high levels of contamination, due to people putting the incorrect materials in these bins, little of this could be recycled.

Instead we now offer general waste bins in these spaces and instruct our staff to collect waste from these spaces and separate it behind the bars so it can be disposed of correctly.

 

Hazardous Waste

The Union has reviewed it procedure for the treatment of hazardous waste and uses the facilities of the College to dispose of these items. 

1. Waste Electrical and Electronic Equipment (WEEE)

WEEE collections from departments must be arranged with College Facilities, found here: ww3.imperial.ac.uk/estatesfacilities/reportrequest/onlineforms/waste/weee.

WEEE equipment is collected by the College’s Facilities Department and deposited at a central compound at South Kensington, where it is collected by the contractor Broadband Recycling who collect all electrical equipment and take it to their facility in Harlow, Essex. All items that have a resale value are sold on and reused.

Everything else is broken down and recycled wherever possible and sold to other companies in the UK to be made into recycled materials.

 

2. Fluorescent Tubes

Fluorescent tubes are collected by College Facilities and placed in a dedicated container at South Kensington. When the container is full then the contractor removes the tubes and takes them to their facility in Manchester where they are broken down into its component parts. The contractor that does this is called Mercury Recycling and the components that are recovered are glass, metals and mercury. Mercury is distilled into a variety of grades and sold onto other lamp manufacturing companies. The metals and glass are used in a variety of industries.

 

3. Used Cooking Oil

This is disposed of individually by catering outlets.  Imperial College Union uses BioUKFuels ( www.bioukfuels.co.uk ).  Used oil is stored on a bund (a metal container with sides) this is in case of spillage of container damage, this prevents oil spills.

When collected, the vegetable oil is converted to bio-diesel – BioUKFuels collect oils or fats and recycle them responsibly into biodiesel at their production facility in Sheffield, or send them for alternative recycling to other licensed facilities.

BioUKFuels’ collection vehicles also use biodiesel to provide an ultra-low emission service.

 

 

Waste Audit, February 2015

Click here to read the full audit finding and recommendations.

The Union asked the Facilities services department of College to conduct an audit on the waste generated from the Union building in the Beit Quadrangle.  Over a week period all waste for the building was audited to ascertain the volume of waste that was generated.

The findings showed that 42% of waste was recycled material that was correctly disposed of (13% paper and Card, 29% mixed). The remaining 58% was waste that was disposed of as General, non-recyclable material. See the graph below.

Waste graph 1

Out of the 58% of waste that was disposed of as non-recyclable general waste, 53% of this was genuine non-recyclable material.

The remaining waste was made up of waste that could have been recycled (4% paper and card, 25% mixed, 17% food, 2% textiles and 0.1% electrical).  See graph below:

It is clear that while the Union pretty good that recycling in general, it also true that improvements in decreasing the amount of recyclable material that is disposed of as general waste can be made.  

As a result of this audit, the Union has taken the following direct actions:

  • Increasing the amount of recycling bins in the bar areas
  • Adding bins for cans in the bar areas
  • Food waste bins for both the FiveSixEight and Dining Hall kitchens
  • Recycling bin for plastic cups, plastic bottles in the bar areas

The amount of recyclable waste that is being disposed of is the union highest established environmental impact. We will be work very hard to increase the amount of this waste that is recycled.

There are other reconditions from the waste audit report and the Union will strive to implement as many of these as possible over the next few months.
