How Skip and Site Waste Is Recycled

Exact procedures vary between facilities and material streams, but most skip and site waste follows a similar path:

1. Collection from the customer’s site. A licensed supplier in our network collects the skip, container or loose waste at the agreed time.
2. Transport to an authorised facility. A registered waste carrier takes the load to a permitted transfer station, materials recovery facility or specialist treatment site.
3. Waste acceptance and weighing. The load is checked against its description, inspected for prohibited items and weighed on a weighbridge.
4. Sorting and separation. Mixed waste is tipped and separated, using a combination of machinery such as grabs, screens, magnets and conveyors alongside hand-picking.
5. Recovery of recyclable materials. Metals, timber, hardcore, soils, cardboard, paper and suitable plastics are separated into their own streams.
6. Onward recycling or treatment. Each stream goes to reprocessors – for example crushed for aggregate, chipped for wood products, or melted down as scrap metal.
7. Residual waste management. What cannot be recycled may be used for energy recovery or, as a last resort, sent to landfill.
8. Duty-of-care documentation. Waste transfer notes and, where needed, consignment notes record what was moved, by whom and where it went.

UK waste law across England, Scotland and Wales is built around the waste hierarchy, which ranks options from most to least preferred:

• Prevention – producing less waste in the first place, for example by ordering materials accurately.
• Preparing for re-use – cleaning or repairing items so they can be used again.
• Recycling – turning waste into new materials or products.
• Other recovery – such as energy recovery from non-recyclable waste.
• Disposal – landfill or incineration without energy recovery.

Businesses that produce or handle waste are expected to apply the hierarchy, and it shapes how facilities process the loads they receive.

The cleaner a load is, the more options there are for recycling it. A skip containing only hardcore can usually go straight for crushing and screening, while a mixed skip has to be sorted first and some material is inevitably lost through contamination. Keeping materials such as timber, metal, cardboard and soil and rubble apart can also make collections more cost-effective.

On larger projects we can coordinate several containers for different streams. In Wales, workplaces have been required since April 2024 to separate key recyclables, and segregation is good practice everywhere. Plasterboard and upholstered seating that may contain POPs must always be kept apart from general waste.

A waste transfer note records the type and quantity of waste, its waste code, the producer, the carrier and where it is going. Businesses should keep these for at least two years. Hazardous waste needs a consignment note in England and Wales, and a special waste consignment note in Scotland, which are normally kept for longer.

Regulation is handled by the Environment Agency in England, Natural Resources Wales in Wales and SEPA in Scotland. Carriers must be registered, and facilities must hold the right permits or exemptions. Our guide to what happens to skip waste covers this journey in more detail.

• Describe your waste accurately when booking so it can be sent to the right facility.
• Separate heavy inert waste from lighter mixed waste wherever space allows.
• Keep hazardous items out and arrange specialist collection for them.
• Flatten cardboard and break down bulky items so they are easier to sort.
• Keep the skip covered to stop rain soaking cardboard and adding weight.
• Re-use what you can – clean bricks, timber and topsoil often have a second life on site.
