Your dining hall has a big blind spot

College students leave about 112 lbs of food on their plates every school year.

Teams need a frictionless way to understand what diners aren’t eating.

Manual Tracking

Expecting busy students to record their own plate waste is a sure path to low adoption (and useless data).

Lack of Insights

You may see plates of untouched chicken rolling down the dishbelt, but don't have context on why there are leftovers.

Smart Data, Sharp Menus, and
Clean Plates

Invisible, Hands-Free Tracking

Get accurate data about what students took but didn’t eat without relying on them to self-scan.

The "Why" Behind Waste

Pinpoint if mac and cheese was tossed because someone didn’t expect pimento or they were too full.

Confident Menu Tweaks

Ensure more of the food you purchase and prepare gets eaten; servings and menu adjustments are based on actual diner behavior.

Awareness without Blame

Students see their waste impact and can answer menu-specific questions. Show your campus you’re listening, not assigning fault.

How it Works

An intelligent system that runs itself

Step 1

Plates are Auto-Scanned

Diners drop their plates on the dish belt, business as usual. Vision AI scanners record all passing plates and determine which menu items, and how much of each, are left. Data is gathered without adding any tasks.

Step 2

Students Engage

On a nearby kisosk, students can see food waste stats and respond to menu-specific questions, like “How was the level of spice in the Pad Thai today?” or “What kind of cookie is your favorite?” This gives chefs the full plate waste story.

Step 3

Insights are Delivered

Weekly reports summarize top wasted items, surface relevant feedback, and provide operational suggestions for chefs and key stakeholders (like dining directors or sustainability teams).

Frequently asked

Your plate waste questions, answered

To record plate leftovers, does someone need to hold their plate up to a scanner or weigh it on a scale?

Nope, tracking is completely hands-free. Scanners are mounted next to a dish return and capture images of every passing plate, so neither students nor staff do anything different. There’s no reliance on voluntary participation (i.e. choosing to scan a plate), so dining teams can fully trust in the plate waste data they receive.

A plate has leftover salmon and broccoli. Will AI identify and tag both? What about the weight of each item?

Yes, AI detects and tags each menu item where there’s more than just crumbs, based on your current menus. “Lemongrass Cod” is identified, not just “fish,” and weight is estimated using 3D imagery.

How is StreamLine plate waste different from other plate waste or post-consumer waste solutions?

No other company offers a system that both engages diners and is hands-free. Checking both boxes is critical. Only seeing opt-in scans skews results, and images can’t tell you why someone didn’t eat their food. Our system achieves the biggest impact with the lowest possible lift.

What are the technical requirements for the dishbelt scanners?

We need Wi-Fi and outlets within 50 ft of the disposal area. We’ll handle everything after that.


For out-of-state installs, we ship all equipment and install on site. Installation takes 3–4 hours. We don’t drill holes in walls. Food scanners attach with velcro adhesive that removes easily without marks. Kiosks are assembled on site and positioned as needed.
