Food waste solutions aren't a single category of tools. Some measure what gets thrown away, some prevent it by tightening ordering, others find a use for surplus that would otherwise be lost. Each solves a different part of the problem, and the right starting point depends on which part is costing you most.

This guide maps the main categories of food waste solutions, shows where each one fits, and compares dedicated tracking platforms in detail so you can start reducing food waste and cutting food costs.

Types Of Food Waste Solutions (And Who They’re For)

Different solutions tackle the problem of managing food waste in different ways. The table below maps the main categories and who each one is built for, so you can see which fits your operation before comparing individual platforms. 

Operations use a combination of these approaches. Inventory, purchasing, and forecasting tools help prevent waste before it happens, while redistribution and processing handle what’s left once it does. But without accurate waste data, it’s hard to know which problems to solve first or whether those changes lead to better food management.

That’s what tracking gives you. It shows what’s being thrown away, down to the ingredient and the shift, so the changes you make elsewhere are based on real patterns rather than assumptions. For a group controlling food costs across locations, that’s the difference between reducing waste intentionally and hoping it comes down. Since tracking is where waste reduction starts, the rest of this guide focuses on the tracking platforms worth comparing and how they stack up. 

What To Look For In A Food Waste Tracking Solution

All tracking platforms do the same basic job: they record what leaves the kitchen. What separates them is how they capture it, and that affects how much you can do with the data. Five differences matter most when comparing them.

• Capture method is how the system records waste. Some capture each item above the bin, while it's still separate. Others record it once it's inside the bin, mixed with everything else. This affects your downstream data because once food mixes together, it's harder to identify.
• Ingredient recognition is how specifically the system names what's thrown away. The difference is between "1kg of salmon" and "1kg of fish." The more specific the data, the easier it is to trace a cost back to its source.
• Manual input is how much staff have to do. Fully automatic systems record everything on their own. Others ask staff to weigh items or pick a category at the bin, which is harder to keep up during a busy service.
• Photo evidence is whether each disposal is backed by an image. This matters for ESG reporting, where an auditor can trace a figure back to a specific record rather than a category someone selected by hand.
• Reporting is what the system does with the data. Some hand you a dashboard to interpret on your own. Others rank the changes likely to cut the most waste, so teams know where to start.

The next section compares the five leading tracking platforms across these five points.

5 Food Waste Tracking Solutions For Reducing Waste And Increasing Cost Savings

The food waste technology platforms below all measure what leaves the kitchen, but they do it in different ways. The more precisely a system shows where food is being lost, the sooner a kitchen can act on spoilage and overproduction before they turn into unsold food and higher food costs. Here's how the five compare. 

1. Orbisk

Orbisk is an automatic food waste tracking system built for commercial kitchens and multi-site hospitality groups.

Capture method

Orbisk records each disposal above the bin, before ingredients mix. Kitchen teams carry on exactly as they always have, and every item is logged while it's still whole and recognisable, even when a handful go into the bin at once.

Ingredient recognition

The built-in AI names 800+ ingredients at around 90% accuracy. Since each item is caught before it blends into the rest of the waste, you get the specific ingredient rather than a rough category.

Manual input

None. Because nothing has to be pressed, weighed, or selected at the point of disposal, the data holds up even at the busiest moments of service, when manual systems tend to slip.

Photo evidence

Every disposal comes with a photo, so each entry is backed by an item-level, timestamped record that withstands cost analysis and external ESG audits.

Reporting

The dashboard lays out what's being wasted, where, and when, and then flags the specific changes most likely to reduce waste. Teams get a shortlist of actions rather than a spreadsheet to decode.

Results

Orbisk customers see up to 70% less food waste, reach ROI within 4 to 8 months, and earn back 2x to 10x what they spend. Results depend on food volume and the amount of avoidable waste a kitchen starts with.

Best for

Multi-site hotel groups and contract caterers that need consistent, accurate waste data across all locations without adding extra steps for kitchen teams.

2. Winnow

Winnow is a food waste tracking platform for commercial kitchens with a long global track record across major hospitality groups.

Capture method

Winnow records waste inside the bin at the point food is discarded. There's no scanning or manual step for staff, and the platform logs the type, weight, and cost of each throw. Since it captures only after food is already in the bin, anything thrown in together has already mixed before it's recorded.

Ingredient recognition

It recognises hundreds of food types but records a single item per disposal. Throw two things away at once, and only one lands in the data, making mixed waste harder to pin down.

Manual input

The higher AI tiers need nothing from staff. Lower tiers lean more on people, so how hands-off the system is depends on the product a given site runs.

Photo evidence

A photo and weight accompany each disposal, providing a visual reference for checking and reporting.

Reporting

Winnow Hub provides group operators with dashboards they can filter by brand, region, and site, with benchmarking to align performance from one location to the next.

Best for

Large international hotel groups and contract caterers after a platform with a proven global footprint and a structured coaching programme.

3. Leanpath

Leanpath offers the broadest product range in the category, from portable manual trackers to fully automatic AI systems.

Capture method

What happens at capture depends on the tier. The AI models identify waste on their own, whereas entry-level devices require staff to weigh and log it. On every tier, waste has to be brought to a tracker and separated by type before it mixes, which asks more of a kitchen than systems that sit at the existing bin.

Ingredient recognition

The AI tiers pick out waste at ingredient level; the lower tiers record whatever category staff select. How detailed the data gets therefore tracks with the hardware a site has chosen.

Manual input

The AI tiers ask nothing of staff. The lower ones require someone to weigh and categorise each disposal, which is tough to sustain through a busy shift and across sites where teams turn over often.

Photo evidence

The AI tiers photograph each disposal to help trace the root cause of waste. 

Reporting

Reporting runs from a single kitchen up to global level, with coaching included and links to Nutritics, Galley, and CBORD that tie waste back to the dishes and recipes behind it.

Best for

Contract caterers and institutional foodservice operators whose kitchens vary in size across sites, or groups that want waste data wired into their menu and recipe systems.

4. Kitro

Kitro is an AI food waste platform for professional kitchens, developed with Swiss university partners and built around one combined camera-and-scale unit.

Capture method

The KITRO TARE sits inside the bin and captures an image and weight each time something is thrown away. As it records after items land, waste has already mixed, and during heavy service earlier disposals can be covered over before the device picks them up.

Ingredient recognition

It names food items and separates edible from inedible waste, logging weight, source, and a timestamp for each disposal.

Manual input

None. Staff dispose of food normally and the unit records it by itself.

Photo evidence

Each throw is stored as an image and weight, viewable in the dashboard and exportable as a PDF.

Reporting

The dashboard breaks waste down by weight, source, and timestamp and surfaces trends by time, item, and station. 

Best for

Mid-size hotel groups and hospitality operators in the DACH region wanting a subscription with hardware included.

5. Positive Carbon

Positive Carbon is a food waste monitoring platform built around a fully automatic sensor, used by corporate operators, hospitals, universities, and sports venues.

Capture method

Positive Carbon logs waste inside the bin, identifying, weighing, and pricing each item as it's discarded. Because it reads waste after it enters the bin, anything thrown in together has already combined by the time it's captured.

Ingredient recognition

The AI Food Identification plan recognises 800+ foods. The entry plan tracks weight alone with no identification, so ingredient-level detail hinges on the tier a site subscribes to.

Manual input

None on the AI tier, where identification runs automatically.

Photo evidence

Each disposal is saved as a timestamped photo and can be exported through the API or as a CSV file.

Reporting

The dashboard adds event and occupancy-based forecasting, so kitchens can prepare for busy days and see how covers feed into waste.

Best for

Multi-site corporate operators and large-volume kitchens where security and compliance credentials are the top priority.

Capture Method: Above-The-Bin vs Inside-The-Bin

The profiles above show how the five platforms differ. The biggest of those differences, and the one worth weighing first, is how each system captures waste. It determines how specific and accurate your data is, which affects how confidently you can use the data to reduce costs and food wastage. Here’s how:

• Above-the-bin systems record waste before it drops into the bin, while items are still separate and identifiable. Because nothing has been mixed yet, the details are still there to capture: what the item is, its weight, its cost. The data reflects specifically what was thrown away rather than an estimate pieced together after the fact.
• Inside-the-bin systems record waste once it's already landed and mixed with everything else. By that point, items have combined, so there's less for the system to identify, and it falls back on broader categories. During busy service, when disposals come fast and pile up, earlier items can be buried before they're captured at all, so information goes missing exactly when the kitchen is wasting the most.

Over time, the difference between the two methods has a substantial impact on food waste management. If a kitchen only knows it wasted 50 kg of food, it can try to reduce waste, but it’s guessing where to start. If it knows that 30 kg came from unused salad ingredients during lunch prep, the team can change ordering or preparation processes and measure whether the fix worked. 

Note: If you’re managing multiple locations, the capture method also affects how useful your benchmarking is. If sites track waste differently or only at a broad category level, a location that looks fine overall could still have specific waste issues hidden in the data. 

Staff Input: Why Relying On Manual Input Breaks Down

The capture method determines what data a system can collect. The next question is whether the data gets collected reliably, and that comes down to how much staff have to do. Any platform that needs staff to log, weigh, or tag waste at the bin depends on them doing it every time, and that slips as soon as service gets busy.

When a disposal doesn't get logged, it doesn't appear in the data. The busier the kitchen, the more gets missed, so the record is least complete during the periods that produce the most waste. Fully automatic systems avoid this because staff don't do anything differently. They throw food away as normal, and the system records every disposal on its own.

The effect grows with each site. One kitchen with a few missed entries is a small problem. Across twenty or fifty locations, each logging inconsistently, the data can't be compared site to site, so benchmarking across the group becomes unreliable.

Questions To Ask When Comparing Solutions To Prevent Food Waste For A Multi-Site Portfolio

If you're evaluating food waste solutions for more than one site, these are the questions to ask every vendor before you commit.

1. When does it capture waste? Does the system record each item before it enters the bin and mixes, or after? This decides whether you get specific ingredients or broad categories.
2. How much can it identify, and how often does it miss? How many ingredients can it recognise, and what share of disposals does it fail to identify? A high recognition rate on paper matters less if a lot goes unlogged.
3. What do staff have to do? Does the system record waste automatically, or do staff need to weigh, tag, or log each disposal? Anything manual gets skipped when service is busy.
4. Is there a photo of every disposal? Does each entry include an image an auditor can check, or just a total weight? This is what makes waste data hold up in ESG reporting.
5. What does it give you back? Does the system tell you which changes will cut the most waste, or hand you a dashboard to work out yourself?

A system that answers all five well gives you consistent, comparable data across every kitchen from the start.

How To Work Out The ROI Of A Food Waste Solution Across Multiple Sites

To build a business case finance will accept, you need three numbers, drawn from how your kitchens run rather than a vendor's projection.

1. What the system costs. The subscription or per-site fee, including the hardware and the software behind it. Ask what's included and what's charged separately, and how the price changes as you add sites.
2. Time saved. If a system logs waste automatically, staff spend no time recording it. Where a system requires manual logging, that time adds up: multiply the minutes per shift by the number of shifts per week, then by the number of sites running it. Across a portfolio, manual logging is a real line on the labour cost, and an automatic system removes it.
3. Food cost recovered. Apply the waste reduction a system reports to your current food cost to estimate what you'd save.
