A concentrated cleaning product can reduce packaging, transport weight and chemical waste, but the benefit disappears if staff over-dose it, decant it into disposable bottles or treat the concentrate as automatically safer. The environmental case depends on the working solution produced, the task it completes and what happens to the container.
This guide is for facility managers, cleaning contractors and procurement teams comparing concentrates with ready-to-use products. It defines a fair basis for comparison and explains how dose, packaging, water, energy, worker exposure and disposal change the result. The aim is not to label every concentrate green; it is to make an environmental claim that can be supported.
Define the Functional Unit Before the Product
Compare products by the work they complete, not by container size. A useful functional unit might be one hundred square metres of routine floor cleaning, one hundred washroom cleans or one month of service at a specified site. State the soil, surface, dilution and cleaning standard. A concentrate that needs a stronger dose or a second pass may use more chemical than a ready-to-use product that works first time.
Record the amount of working solution used, the concentrate volume consumed and the number of containers opened during the period. Without those inputs, a smaller bottle can look better simply because it contains less product. The Work Health and Safety Regulations 2011 also make the risk assessment and information duties relevant when the product is used at work.
Identify the Environmental Claim Being Made
Separate the possible claims. A product may reduce packaging per litre, reduce transport weight, use less water at the point of use, avoid a particular ingredient or carry an independent certification for a defined scope. Those are different claims and need different evidence. βEco-friendlyβ does not identify what was measured, compared with what, or across which life-cycle stage.
Ask the supplier for the exact wording and supporting document. Check the product, pack size and manufacturing site named in a certificate. A certification for one product does not transfer to another concentrate in the range. A recycled-content claim for a bottle does not prove the contents are less hazardous, and a low-phosphate formula does not prove the whole product has a lower impact.
Distinguish absolute claims from comparative claims. βContains no added fragranceβ is an ingredient statement that can be checked on the formulation and SDS. βProduces 30 per cent less packagingβ is a comparative claim that needs a baseline, a functional unit and a defined boundary. Ask whether the comparison includes the outer carton, labels, dosing equipment and the secondary bottles used on site. A claim based only on the primary container can be true yet tell the buyer very little about the service.
Check the date of the evidence and the product version. A reformulated concentrate may have a different dilution or hazard profile. A packaging change may alter the recycled content or the closure material. Keep the current technical data sheet and certificate with the current pack code. If the supplier cannot state which version the claim applies to, request a clarification before the product goes into a tender response.
Compare Dose, Performance and Over-Dosing Risk
A concentrate creates an environmental benefit only when the working solution is made to the label ratio and cleans in the specified number of passes. Measure the dose with a calibrated cup, dispenser or pre-measured pod. Test the product on the actual soil and surface. If the cleaner adds extra concentrate because the first mix does not work, the packaging saving can be offset by chemical use and rework.
The Agar Superforce concentrate is listed by Freshway with a dilution ratio up to 1:160 for suitable applications. The Eureka Sparklex window concentrate is listed as one litre making up to 100 litres of working solution. Those figures are useful starting points, but the site still has to confirm the correct dose for its soil and method. Use the commercial dilution method to convert the label ratio into a measurable volume.
Account for Packaging and Refill Behaviour
Compare the packaging needed per working litre, not just the primary bottle. Include the concentrate container, measuring equipment, secondary spray bottles, labels, caps and any single-use refill pods. A concentrate supplied in a recyclable drum can perform worse in practice if staff transfer it into a new disposable bottle every shift or discard the measuring cup.
Ask whether the container is reusable, refillable or accepted in the site's recycling stream. Check the local council or waste contractor requirement rather than assuming that a resin code guarantees collection. The Australian Packaging Covenant Organisation provides a national framework for packaging sustainability and design, but the site still needs to confirm what its collection service accepts.
Include Transport and Storage in the Comparison
A concentrate reduces the weight and volume moved per working litre, which can reduce transport and storage requirements. That benefit is relevant only if the product is ordered in a quantity the site will use before it expires. A large drum bought for a small site can create surplus stock, a storage hazard and disposal cost.
Record delivery frequency, pack size and the space required for secondary containment. A concentrate that needs a dedicated dispensing station, spill kit and trained operator may still be the better choice, but those requirements belong in the trial. Do not count the transport saving while ignoring the packaging and energy used by the dispensing system.
Consider the return journey as well. A reusable container only reduces packaging if it is collected, cleaned and refilled through a controlled loop. A container that is designed to be recycled but placed in a general-waste bin has not delivered the intended result. Ask the supplier how the empty package is handled and whether the site's waste contractor accepts the material. If the answer depends on a local service, record that condition in the procurement file rather than presenting the container as universally recyclable.
Storage also affects waste. A drum that is too large for the site can sit for months, pick up contamination and be disposed of before it is used. Choose a pack size that matches the measured consumption between deliveries and the available containment. A concentrate should remain a concentrate until it is needed; making a large batch that will not be used within the product's stability period turns the packaging saving into a disposal problem.
Assess Water, Energy and Waste at the Point of Use
Mixing a concentrate uses water at the site. A ready-to-use product arrives with water already in the bottle. The comparison should include the water used to dilute and rinse, the energy used to heat water or operate dispensing equipment, and the waste water generated. In many cleaning tasks, the amount of rinse water and the number of passes has a greater effect than the product format.
Reduce impact by controlling the dose, using the lowest flow that cleans, avoiding unnecessary rework and disposing of wash water through the approved route. The NSW Environment Protection Authority water guidance explains why cleaning runoff must be kept out of stormwater and managed under the relevant site controls.
Read the SDS for Hazards and Exposure
A concentrate can have a higher hazard classification than the diluted working solution, and the concentrated product can be more dangerous during decanting. Compare the SDS for both the concentrate and the working concentration. Check the required PPE, ventilation, incompatibilities, first aid and spill response.
Provide a dispensing point that controls splashes and keeps concentrates away from food, drink and unauthorised users. Label every secondary container with the product and dilution. A lower-impact ingredient claim does not remove the need for safe handling. The WorkSafe Victoria hazardous substances guidance and SafeWork NSW resources can support the site's risk controls.
Check the Full Product Family, Not One Bottle
Facilities often need several products for different soils and surfaces. A concentrate range can reduce packaging if it shares a dispensing system and replaces several ready-to-use lines. It can also increase complexity if every product needs a different tip, dose chart and bottle colour. Compare the whole range needed to complete the site's tasks.
Keep the range small enough for staff to learn the doses and labels. The commercial chemical selection guide explains how task-based standardisation can reduce unnecessary products. Standardisation is an environmental control when it lowers duplication, over-ordering and leftover stock.
Test the Claim in a Controlled Site Trial
Run a trial on one route or building. Record the working solution made, the area cleaned, passes per area, product consumed, packaging generated, staff time and complaints. Include the concentrate and a current ready-to-use product as controls where that is practical. Use the same operator and cleaning standard for both.
Measure over more than one shift. A concentrate that works on day one but causes rework on day five is not a lower-impact replacement. Check the container condition, label legibility and dispensing accuracy after repeated use. Include the cleaner's view of mixing time, spill risk and ease of carrying the product.
Set a stop condition before the trial starts. If the product needs more than the approved dose, causes surface damage, creates an unacceptable exposure risk or increases the number of passes, the trial has not demonstrated an environmental improvement on that site. Stop and record why. A partial result is more useful than rolling out a product that only looks better because the trial did not count rework or leftover solution.
Questions We Get Asked Most
- Are concentrated cleaning products always better for the environment?
- No. They can reduce packaging and transport per working litre, but the benefit depends on correct dosing, task performance, container reuse and disposal. A concentrate that is over-dosed or wasted can have a worse result.
- What is a concentrated cleaner?
- A concentrate contains the active cleaning ingredients at a strength intended to be diluted before use. The label states the suitable dilution, surfaces and method. It should not be used at full strength unless the product instructions say so.
- Does a smaller bottle mean less packaging?
- Only when it produces the same cleaning result with the correct dose and does not require extra secondary containers or discarded leftover solution. Compare packaging per completed task, not per bottle.
- Are green or eco labels enough evidence for a procurement decision?
- No. Ask for the exact claim, certification scope, product name and supporting document. Check the product's SDS, performance and local recycling arrangements before choosing it.
Record Substantiation for Procurement
Keep the supplier claim, SDS, dilution chart, trial result, pack size, recycling information and any certificate in the product record. Name the person who approved the comparison and the date. If a product changes formulation or pack, reassess the claim rather than carrying the old wording into the next tender.
Use the cleaning chemical range to compare concentrates and reference the Freshway Floor Cleaner 380 and the spray-bottle compatibility guide where decanting is part of the method.
Conclusion
Concentrated cleaning products can reduce impact when a measured dose produces the required result with less packaging and transport. They can increase impact when over-dosing, secondary packaging, storage surplus or unsafe handling are left out of the calculation.
Make the claim specific, test it on the real task and record the evidence. That approach supports an honest procurement decision and gives the cleaning team a method it can repeat.
For the next tender, include the functional unit, measured dose, packaging boundary, trial result and review date beside the price. Those five fields make competing products comparable without relying on a broad sustainability label.
Review the file whenever the product formulation, pack size, supplier or waste service changes so the evidence remains tied to the product actually being purchased by the site.
Keep the current evidence with the current product record.
