Typically procurement departments go out and correctly negotiate to the best known commercial rates, common across all sites.  Gathering first historical data, cost p/bin rates, cost p/ton, cost p/collection etc  All standard negotiables.   Pre and post tender, there could be a +/- 5% difference to the previous rate paid. 

Waste however is an anomaly. The disparity comes in that Procurement’s negotiations don’t take in to account the numerous variables that make every site different and therefore every waste strategy different.

The variables that make the difference are:

1. The Tenant Mix – Different waste streams from different shops 
2. The amount and type of food outlets
3. Whether or not the site has dedicated waste staff
4. The amount of storage their waste area can handle
5. If the site has waste equipment or only bins (and what size the bins are)
6. How far the waste has to be moved

E.G  A charity shop’s waste can be well over 1000% that of a store like Holland & Barratt. A Nightclub produces 90% recyclable waste.  A Dining centre may have 80% food waste – the heaviest waste (@£140 p/tonne) that could be disposed of for £30 P/tonne if treated.  What % of the bins are being collected with waste in to the weight limit?

These variables can affect your prices by far greater values than any possible negotiations.  Knowledge enables an informed decision, evaluation of the figures and efficient staff.
