The waste stream section of a site waste management plan

The waste stream section is the part of a site waste management plan that does actual work. Everything else in the document describes intentions. This section forecasts what the project will produce, stream by stream, in tonnes, and sets out where each stream goes, which is what a council checks when the condition comes back for discharge.

Site waste management plans stopped being a statutory requirement in England when the 2008 Regulations were revoked, but they did not go away. Councils require them through conditions and local plan policy, the waste hierarchy duty in the Waste (England and Wales) Regulations 2011 still applies, and the duty of care under section 34 of the Environmental Protection Act 1990 governs every movement off site.

What the section forecasts

Three things, for each stream: how much arises, how it will be handled, and where it goes.

The forecast is made before work starts, using the demolition survey, the excavation quantities from the earthworks design, and benchmark rates for construction waste per square metre of floor area. It is then revised as the design develops, because the figure produced at planning stage from outline drawings will not survive contact with the technical design.

Streams should be listed separately rather than aggregated into "inert" and "other". A plan that shows one line for 4,000 tonnes of mixed waste tells the officer nothing about segregation, and it makes the diversion claim impossible to verify.

Estimating arisings by stream

Work through the project in the order the waste actually arises.

Demolition and site clearance produce the largest tonnages: concrete, brick and block, timber, metals, glass, and anything hazardous identified by the pre-demolition survey. Asbestos is the critical one, and the refurbishment and demolition survey has to be completed before any intrusive work, not as a formality afterwards.

Excavation produces soils and made ground. These dominate the tonnage on most sites and are the stream with the largest scope for on-site reuse, subject to the material being suitable and to the waste status question being addressed properly. Where a contaminated land assessment identifies material requiring treatment or disposal, the tonnages and the classification belong in the forecast rather than in a vague allowance.

Construction produces packaging, timber offcuts, plasterboard, insulation, cable and pipe offcuts, metals, and the general mixed waste that makes up most skip contents. Plasterboard needs its own line because gypsum cannot be landfilled with biodegradable waste and must be segregated.

Fit-out and commissioning produce packaging in volumes that surprise people, particularly on residential schemes where every appliance, sanitary ware item and light fitting arrives boxed.

Segregation on a constrained site

Segregation at source produces better diversion rates and lower disposal costs than off-site sorting, and it needs space that a tight urban site does not have. This is where the plan has to be realistic.

Set out the actual arrangement: how many skips or containers can stand on site at once, where they go on the phasing plan, how they are accessed by the collection vehicle, and what happens during the phases when the compound moves. A plan that assumes six segregated streams on a site with room for two skips will not be followed, and nobody benefits from that.

Where segregation on site is impossible, say so and specify a licensed materials recovery facility that sorts mixed waste, with its recovery rate stated and evidenced from the operator. That is a legitimate approach, and it is more credible than a segregation scheme that exists only on paper. The vehicle access for collection should match the swept paths already prepared for the waste collection strategy so that the operational and construction phases are consistent.

Diversion targets and how they are evidenced

Diversion from landfill is normally expressed as a percentage of waste by weight that is reused, recycled or recovered rather than sent to landfill. Some local policies set a specific target for construction and demolition waste, and the London Plan sets targets for beneficial use that referable schemes are expected to meet, so check the wording that applies rather than assuming a standard figure.

Evidence is weight-based and comes from the waste documentation.

• Waste transfer notes for every non-hazardous movement, describing the waste, its European Waste Catalogue code and the receiving site.
• Consignment notes for hazardous waste, including asbestos and contaminated soil.
• Weighbridge tickets or contractor weight records reconciled against those notes.
• Confirmation of the receiving facility's permit and, where a recovery rate is claimed for mixed waste, evidence of that facility's actual performance.
• Records of material reused on site, which counts towards the hierarchy but does not appear in transfer notes.

That last category is the one most often lost. Crushed concrete used as piling mat or capping is a real diversion, and if nobody records the quantity it disappears from the final reconciliation.

Duty of care documentation

The duty of care applies to everyone who produces, carries or receives waste. In practice the contractor must check that each carrier is registered with the Environment Agency, that the receiving site holds the right permit or exemption, and that the waste is described accurately on the paperwork.

Checking the carrier is not a formality. Fly-tipping cases regularly end with the waste producer liable because nobody verified the registration, and the registration check takes a couple of minutes on the public register. Keep the record of the check with the transfer notes.

Retention periods matter for condition discharge. Transfer notes must be kept for two years and hazardous waste consignment notes for three, but where a planning condition requires a completion report, keep everything until that report has been accepted.

Reporting actual against forecast

The reconciliation at the end is what turns the plan from a submission document into something useful. Report, by stream: the forecast tonnage, the actual tonnage, the destination, and the diversion achieved, with variances explained.

Variances are normal and should be explained rather than smoothed over. More soil than forecast because the ground investigation underestimated the depth of made ground. Less inert waste because more was crushed and reused. A hazardous stream nobody anticipated, found during strip-out.

Where the project falls short of a target, say so and explain what caused it. An honest report identifying a shortfall and its cause is far easier for an officer to accept than a report that reaches exactly the target figure with no supporting detail. And it gives the contractor something to use on the next scheme.

Where the plan becomes a condition

Most site waste management plans arrive attached to a pre-commencement condition requiring submission and approval before work starts, sometimes with a further requirement for a completion report within a stated period after practical completion.

Read the condition wording carefully, because the obligations follow it precisely. If the condition requires the plan to be implemented as approved, a change to the segregation strategy on site is a departure from an approved document, and the route back is a variation rather than an explanation later. If it requires a completion report within three months, diarise it, because discharge applications for lapsed conditions are avoidable work.

Where the condition sits alongside a construction management plan, align the two documents. The waste plan's container positions, vehicle movements and collection frequencies should match the construction traffic and site layout in that plan rather than contradicting it.

A site waste management plan drafted with real quantities, named streams and evidenced destinations takes longer to prepare and much less time to discharge.
