Compost-Flow
A sieve-tray unit where garden waste filters down slowly as it decays, through trays with progressively smaller holes.
- Stacked trays with graduated sieve holes
- RFID tags embedded in trays 1 to 3
- Hinged door for easy tray access
Compost-Flow® is a smart modular composting system designed to help gardeners and urban households compost more effectively. A structured sieve tray system with simple condition monitoring via a solar-powered sensor probe and a companion app Optional.
Know when a tray is too wet before it starts to smell.
A closed, structured unit keeps scraps contained and covered.
Clear alerts tell you when heat or moisture drifts out of range.
A compact vertical footprint for gardens, patios and balconies.
Garden and food waste goes into the top tray. As it breaks down, it filters slowly through to the trays below.
Each tray has smaller sieve holes than the one above, so material separates naturally as it decays.
Place the Compo-Sense probe in a tray. It detects which tray it is in by RFID and records temperature and humidity.
CF-Connect shows the condition of every tray, sends alerts when something needs attention and offers guides and tips.
Each part works on its own. Together they take the uncertainty out of home composting.

A sieve-tray unit where garden waste filters down slowly as it decays, through trays with progressively smaller holes.

A moveable, solar-powered probe that tracks conditions inside each tray and shows readings on its display or syncs them to the app.

The companion app the probe syncs to. It gives a clear view of every tray, alerts when action is needed, and step-by-step guidance.
Because each tray carries its own RFID tag, the probe knows exactly where it is. Readings are logged against the right tray, so you can see each stage of decomposition at a glance.
Example readings, as shown in CF-Connect.

See the stage of each composter, how long until it's ready, and which tray needs your attention.
Track the heat that shows your compost is working.
Catch a batch that's too wet or too dry before it fails.
Get notified when a tray needs turning, watering or more browns.
Simple tips for greens, browns and getting the balance right.

Founder & designer
“I want to turn big ideas into tangible, meaningful products.”
I'm a Product Design graduate from Brunel University London with First Class Honours. I'm passionate about sustainable design and hands-on prototyping, and I enjoy working directly with materials, whether 3D printing, building in the workshop or refining a model by hand.
I like solving problems creatively and practically, and I'm always looking for ways to make products more intuitive, inclusive and responsible.
