Landfills are an increasingly pressing problem. Less and less land is available to deposit refuse, but the volume of waste is growing all time. As a result, segregating waste is not just of environmental importance, but of economic concern, too.

32 Sort waste into paper, cardboard, glass (and other recyclable materials), compost, hazardous waste, and residual waste

The most rational way to cope with all this rubbish is to collect it at source in each area and to separate it immediately where possible. The way that waste is sorted must reflect local disposal systems. The following categories are common:

• Paper
• Cardboard (including packaging for return to suppliers)
• Glass (clear, tinted – no light bulbs or window panes, which belong with residual waste)
• Plastics
• Scrap metal
• Compost
• Special/hazardous waste
• Residual waste

33 Return packaging to suppliers

More and more organisations have begun to return packaging to suppliers. If cardboard is always sent back, hostel waste could be reduced by about 20 per cent.

34 Collect and dispose of organic waste separately

Organic waste should also be segregated for disposal. The following categories are recommended:

• Leftover food which has had any contact with meat should be collected separately to prevent the spread of bacteria.
  - Meat and bone should be retrieved by bodies responsible for animal waste
  - If other leftovers are sent, for example, to local farmers, they should be sterilised before being fed to the animals
• Peel and scrapings from fruit and vegetables can be composted along with other degradable matter. Other waste can be included for composting, too, such as cut flowers, corks, coffee grindings, rotting fruit, tea bags, egg- and nutshells, paper towels etc.

35 Filter grease and oil

Chip pan oil, used fat, vegetable oil and the content of fat filters should be collected by companies able to re-use them. Local authority waste departments can provide relevant addresses.

36 Offer guests opportunities to segregate waste for recycling

This can be achieved by providing bins in communal areas for segregated waste. It is important to involve your guests in your recycling policy. It is important to make sure that recycling information for your customers is prominently displayed or included in a welcome pack, with clear instructions about what you would like them to do.
