Trade waste storage and bin stores for a commercial unit

Commercial bin store planning questions sink more small change of use applications than almost anything else, and the reason is that the problem is physical. You can argue about use class and trip generation. You cannot argue a 1,100 litre bin into a 900 millimetre passage. If the unit has no rear access, no yard, and a frontage onto a footway, the waste strategy is the application's weakest point, and the officer will find it.

So do the arithmetic first, before the fit-out drawings. Calculate the volume the operation will produce, work out how many bins that is, find somewhere to put them that is not the pavement, and check that the collection vehicle can reach them.

Why the store decides the application

Trade waste is on most councils' local validation lists for change of use applications, which means an application without a waste strategy can be returned as invalid before it is even assessed.

Beyond validation, three policy issues attach to it.

Amenity, because bins near a residential window produce odour and noise at collection time, and collections for commercial premises often happen early.

Highway and footway obstruction, where bins presented on a narrow footway or left out between collections obstruct pedestrians and particularly wheelchair and pushchair users. Councils are increasingly firm about this and the highway authority will comment.

Visual impact on the street, where a bin store in front of a shopfront in a conservation area or a secondary shopping frontage is a design objection in its own right.

A food business adds the environmental health dimension: food waste, wash-down, pest control and the separate storage of different waste streams.

Calculating the storage volume

Work from the operation, not from a rule of thumb. The method that stands up:

1. Establish the waste streams the business will produce: general, dry mixed recycling, glass, food waste, cardboard, and any special waste such as cooking oil or clinical waste.
2. Estimate the weekly volume of each from the business plan, using covers per week for a restaurant, transactions for a shop, or floor area where no better figure exists.
3. Convert to bin capacity, remembering that cardboard needs volume rather than weight capacity and that glass is heavy and needs smaller containers.
4. Divide by the collection frequency to get the standing storage requirement, and add a margin for a missed collection.
5. Check the total against the space available and the door widths, swept paths and turning space to move a bin from store to collection point.

Standard container sizes used by commercial collectors are typically 240, 360, 660, 1,100 and 1,280 litres, plus wheeled food waste bins at 23 and 140 litres and cardboard cages. Those capacities are the constraint: you cannot specify a bin that does not exist, and a store sized for an abstract volume rather than for real containers will not work.

Many councils publish waste storage standards in a supplementary planning document or a design guide, with required volumes per unit type and bin store dimensions. Where those exist, use them, and where they do not, use the collector's own container sizes and justify the volume calculation openly.

Siting the store

The hierarchy of acceptable locations, best first:

An internal store within the unit, ventilated to outside, with a direct route to the collection point. This is the answer that avoids every objection and costs floor area.

A rear yard store, screened, on a hard surface with a drained wash-down point.

A store within a side passage or service alley, where the passage is wide enough to move the bins and does not cross a neighbouring title.

A purpose-built external enclosure set back behind the building line, with a solid gate and a planted surround.

What does not work, and gets refused: bins on the forecourt in front of the shopfront, bins presented permanently on the footway, and a store that requires bins to be dragged through a food preparation area. That last point is an environmental health objection rather than a planning one, and it will come back through the officer anyway.

Where the unit shares a yard with other occupiers, the landlord's consent and an allocation of space have to be documented, because a shared yard with no allocation produces exactly the dispute officers are trying to prevent. Our note on cash and carry to trade counter and the retail tests deals with a related evidential problem where the operational description matters.

Collection access and drag distance

The drag distance is the distance a collection operative has to move a bin from the store to the vehicle. Councils and private collectors set limits, commonly in the range of 10 to 25 metres for wheeled bins on a level, smooth surface, and the figure is usually published in the authority's waste storage guidance.

What to show on the drawing:

• The store location and the collection point, with the drag route marked and dimensioned
• The surface along that route, since gravel, steps and cobbles are not acceptable for wheeled bins
• Any gradient along the route, with the fall stated
• The vehicle swept path where the collection vehicle has to enter the site, using the collector's vehicle dimensions
• The presentation arrangements if bins are presented at the kerb, including where they stand while awaiting collection and who moves them back

Where a refuse vehicle needs to reverse, expect resistance. Reversing manoeuvres on a public highway are a recognised risk, and a design requiring a reversing collection is likely to attract a highways objection. A turning head sized for the authority's vehicle is the answer where the geometry allows.

A Transport Statement is the place to set out servicing and refuse vehicle access where the site generates enough movement to warrant one, and our note on nurseries in commercial units and drop-off covers how servicing and drop-off interact on a constrained frontage.

Odour, vermin and wash-down

The detailing that answers environmental health, and that officers look for:

A sealed, impervious floor with a fall to a trapped gully, connected to foul drainage rather than to surface water. Approval from the sewerage undertaker may be needed for a trade effluent discharge where wash-down water carries food residue.

A water supply for wash-down, which means a tap in or adjacent to the store, frost protected.

Ventilation that does not vent towards a residential window or a doorway, with openings designed to exclude rodents and birds.

Hard, cleanable wall surfaces to a usable height, and no voids behind cladding where rodents can nest.

Lockable, close-fitting lids and a gate that closes, because an open store is the thing that creates a vermin problem.

Separation of food waste from general waste, with food waste on the most frequent collection and in the coolest part of the store.

Where the use involves refrigeration or extract plant beside the store, the plant noise and the store will be assessed together. The acoustic case is covered in our note on cold stores and refrigeration plant noise, and extraction is dealt with in the Ventilation and Extraction Statement.

What to submit

A short package answers this completely, and it is far less work than the resubmission:

A plan at 1:50 or 1:100 showing the store, its internal dimensions, the containers drawn to size and labelled with their capacity, and the door or gate opening. A site plan showing the drag route dimensioned and the collection point. A short written waste strategy giving the streams, the calculated volumes, the container schedule, the collection frequency and the collector arrangement. Elevations of any external enclosure, with materials. And confirmation of landlord consent and space allocation where the yard is shared.

Two sentences in a covering letter will not do it. A drawing with bins shown to scale is the single most persuasive thing you can submit, because it demonstrates the thing the officer is worried about: that the bins actually fit.
