Waste contracting made… practical
By: Mike Ritchie, MRA Consulting Group

Did you know that waste/recycling contracts are generally the largest and most valuable contracts that a Council signs?
Did you also know these are the most important greenhouse gas decisions a Council can make?
Waste decisions also touch every household, every ratepayer and every voter, every week.
So, getting them right is important.
If you havenât seen it, have a look at the news right now about the garbage strikes in England. Waste is piling up around households and shops. Rats are having a field day.
In my view, it is also not very difficult to put in place a proper contract that runs well; to the benefit of all parties involved.
Many readers can recall examples of multi-year tender process that have failed, for many reasons. No one tendered, no tenderers were selected, no contract awarded, contract awarded but not executed, contract failed and ended in dispute.
This article explores some simple principles of tendering and contracting that MRA recommends for all the local government contracts we assist with.

Here is the short version:
- Be clear on the Scope
- Understand risk and allocate it properly
- Model Contracts save time, risk and money
- Understand Capital and provide for its funding
- Be mindful of Probity matters
- Contract structure BOO/BOOT/D&C/Purchaser Provider matters
- Variations are ok but not too much
- Contamination matters
- Education costs are real
- Regional considerations
And hereâs the slightly more detailed version:
- Scope â For Collection contracts, this is straightforward. But Processing can be complicated. Who is responsible for what, when and how? Take time and make sure all the stakeholders are on-board with what is being contracted. This is particularly true for groups of Councils in a regional contract. Time spent clarifying scope is not wasted. It is crucial. MRA uses a âTenderer Questionnaireâ with about 100 questions to document exactly what the Scope and Specification need to do.
- Risk â Understand risks. They are unavoidable in contracts. The key is to assign them to the party best able to manage and mitigate them. For example, put âProduct Commodity Riskâ on the MRF. They understand commodity trading and do it every day. Councils do not. But donât put landfill levy increases onto the MRF. They cannot mitigate it or avoid it. (If they are very sensitive to it, they may not tender at all.) If it is passed to them, it will just cut their margins and impose a commercial stress. Who wants that? Each risk should be identified and allocated according to who is best to manage it. (Which brings me to Model Contracts).
- Model Contracts â use them. Most of the risks have been identified and allocated (sensibly). Here are links for NSW, Vic and SA Model Contract processes. Put a good waste adviser, probity and legal team together and you have the package.Â
Some free advice â Donât use the Councilâs âGeneral Services Contractâ. It is not designed for waste. Similarly, donât commission lawyers to write a new contract. It will cost a fortune and not add value. The lawyersâ role should be to review the contract documents you propose to use. Most Model Contracts have been tested legally, and they do the job. You just need to make sure the Specification deals with the Scope and Risk as mentioned above. If the Model Contract does not quite do the job, amend it. Donât reinvent the wheel. - Capital â Generally Councils should allow the contractor to depreciate their capital over a longer period if they donât want the gate fee or service fee, to explode. The higher the capital contribution (think new MRF, new trucks etc) the longer the contract period should be. That will keep the gate fee or lift cost at a reasonable level. Trying to crunch high capital contributions into a short contract period, will result in a high unit cost.Â
- Probity â Get the probity adviser in, early and often. Too many tenders get derailed due to conflicts (or perceived conflicts).
- Contract structure â Coffs Waste 2025 is coming up and I am confident there will be multiple talks on contract structures such as Purchaser Provider, BOO (Build Own Operate), BOOT (Build Own Operate Transfer), D&C (Design and Construct) and Alliance Partnering.
Letâs keep it real. Most Collection and Processing contracts are Purchaser Provider. Council âPurchasesâ a service from a trucking collector or a MRF Operator, Composter or Landfill/EfW âProviderâ. Although it does happen, it is relatively rare that a Council or group of councils procures the construction of a new facility.Â
This is where BOO, BOOT, D&C and Alliance Partnering come into their strengths. (Before someone has a go at me, yes, there are a couple of Alliance Partnerships in the collection sector, but you can count them on one hand in Australia).Â
If you are seeking a new capital build, then seek proper contract structure advice. Properly explore options (Scope above) before landing on the contract model. There are a couple of Model Contracts which are useful. - Variations â Some Contractors love to put in big lists of variations during the Tender Process. I do caution about accepting large amendments during the Tender Process itself. If a wide range of variations are accepted, it can mean that the tendered contract is fundamentally different and should therefore be re-tendered (so all competitors have an equal opportunity).Â
All operating contracts should have variation clauses (if nothing else but to allow for innovation and Changes in Law). Price for example, should be subject to variations for CPI or Rise and Fall (depending on the contract length and what it is for). Holding a contractor to a fixed price, irrespective of all else, is a recipe for failure. At least talk. - Contamination â I call out Contamination as a special risk in the waste/recycling sector. Who should own Contamination risk? The answer is of course where it can be best managed and mitigated. That is almost always shared between Council and the Operator.Â
Council should own the contamination risk associated with education (or lack of it) and the contamination that is presented to a Processor. This is done by the inclusion of âcontamination bandsâ into MRF, AD and Composting contracts (and Collection, where appropriate). The Council pays a marginally higher price for higher contamination rates. That sends the right price signal to Council and compensates the Processor for additional costs of dealing with contamination.Â
Note: Forcing a Processor to take all contamination risk at any level of contamination, may feel like a win at first but it will lead to contract pain and disputation over time. It goes against the principle of risk allocation discussed above. It will obviously result in higher prices as Processors hedge risk.
Along the same vein though, the Processor should bear the contamination risk for the products it produces. If it produces a contaminated compost and cannot sell it for a high price, that is the Processorâs risk. If it produces a high-grade compost that sells brilliantly, then it enjoys the higher revenues.Â
If the Parties decide to share these risks, then that is equally good. Just define them properly and share the upside and downside. - Education â This follows on from the Contamination discussion above. Some Councils ask their Collection Contractor to manage community education (usually for simplicity). I am not a big fan.
Councils are best placed to target education to the right people for the right reasons. If there are contamination bands in the contract, then the economic signals are direct and obvious. Where the Collection Contractor is not the Processor, education priorities can be confused and economic signals weakened.Â
It is now common for Councils to include the costs of education in their collection contracts (e.g. $5-10/hh/yr paid by the Collector to Council annually, thereby recognising education as an essential and ongoing, annual cost of the waste service). Council can then engage anyone it likes to deliver the education services. This could be the Collector, a PR firm, Council staff or other. It maximises the targeting of the education spend to what is needed. - Regional contracts â A special note for Regional Groups of Councils and combined contracts. One of the biggest uncertainties in multi-Council tenders is the commitment of tonnes. If you want a lower price (usually the point of regional tendering) then it is crucial that tenderers have certainty about the tonnage they are tendering for. If each Council keeps an opt in/opt out position it undermines certainty and will result in a less competitive tender process (and higher prices).Â
MRA recommends that Councils pre-commit their tonnes prior to tender. In practical terms we suggest they agree a threshold price before commencing the tender process. (The threshold is always confidential). If the price comes in under that threshold, then Council tonnes have been locked in already. It gives tenderers confidence that their tendering effort will be respected, and a contract will be forthcoming to the winner. It eliminates the perception of âfishing expeditionsâ.
I could go on, but I donât want to sound like one of those lawyers at conferences, who try to fill your heads with complexity and risks that only they can solve.
Keep it simple and keep it real.
