Organic Waste Treatment Services
Authority: arc21 (Central government)
What is being bought
Published requirement descriptionarc21 is a local government waste management group, based in Northern Ireland, who act as a contracting entity, procuring and managing waste contracts, on behalf of its constituent councils. The constituent councils are Antrim & Newtownabbey Borough Council; Ards & North Down Borough Council; Belfast City Council; Lisburn & Castlereagh City Council; Mid & East Antrim Borough Council; and Newry, Mourne & Down District Council.
In 2008, arc21 awarded a contract for the treatment of organic waste and in 2023/24 there was circa 148,000 tonnes of food and garden waste processed through it. The current contract is due to expire at the end of November 2029 and the purpose of conducting a preliminary market engagement is to obtain the views of potential private sector partners on the key issues involved in procuring and delivering new organic waste treatment contract(s) in the region, to inform the decision-making process in relation to how the organic waste from within the arc21 area is to be treated after the end of the current contract. The dates relating to the contract and extension periods contained within this notice are not fixed and the ultimate contract and extension dates will be informed by this market engagement exercise.
The engagement is intended to help shape arc21’s requirements and procurement strategy.
Further information can be found in the Information Memorandum.

How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
i
How often small and medium firms win.
Share of awards where the winner’s size is known.
The counts under this question show how many awards have a known supplier size.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
i
How often local firms win similar work.
Winners with a registered address in the delivery region, out of awards with a known address.
Here, local means registered in Northern Ireland (authority’s region).
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered in Northern Ireland.
i
How long buyers here take to decide after bids close.
Middle value in days from the deadline to the first award notice, on competitions that published both dates.
Only decided tenders count, so slow ones still waiting are not in.
Half of these awards were announced within 37 days of the bid deadline.
i
How often work is awarded with no recorded rival.
Direct awards and tenders where every published lot count shows one bid.
The market share is a minimum: some awards have no bid count.
Thin markets produce this too; it is not proof of a tailored specification.
Direct awards or one recorded bid are common here. Check the route before spending time on a bid.
How many bids did past lots attract?
i
How many bids past lots received.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
- Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
