How Our Household Composting System Works
A Clean, Local Way to Turn Food Waste Into Living Soil in Bristol
⭐⭐⭐⭐⭐ Rated 5.0 on Google
The Bristol Living Compost Project uses a simple, proven system to keep food waste local, compost it biologically, and return nutrients to Bristol soil.
No smells.
No maggots.
No long-distance transport.
Just a clear loop from kitchen to compost to soil.
The Big Picture
Most food waste systems are designed to remove waste from cities.
Our system is designed to restore soil.
Food scraps collected through the Bristol Living Compost Project are:
-
Kept within the city
-
Stabilised through fermentation
-
Composted biologically
Living compost is returned to:
-
gardens
-
allotments
-
schools
-
growing spaces
Your food waste doesn’t disappear.
It does useful work.

Step-by-Step: How the System Works
This is the same process for every household member.
It’s designed to be clean, reliable, and easy to live with.
1. Food Scraps Are Collected at Home
Households collect food waste using:
-
a clean, sealable 20-litre bucket
-
bokashi bran containing beneficial microorganisms
You can add:
-
fruit and vegetables
-
cooked food and leftovers
-
bread, grains, tea bags
-
coffee grounds and eggshells
The bokashi fermentation process:
-
prevents rotting
-
suppresses odours
-
keeps flies and maggots away
-
stabilises nutrients early
No plastic.
No liquids.
Buckets are suitable for kitchens, flats, and small homes.
2. Collections Happen Locally in Bristol
When your bucket is full, you request a collection. We:
-
collect food waste across Bristol
-
swap your full bucket for a clean one
-
top up your bokashi bran
Collections are planned to keep routes short, efficient, and local.
Food waste is not transported out of the city.
3. Fermentation Protects Nutrients
Before composting, all food waste is:
-
fermented using bokashi microorganisms
-
acidified to prevent nutrient loss
-
stabilised so it does not smell or attract pests
This step protects carbon, nitrogen, and trace nutrients that are often lost in conventional food waste systems.
Fermentation is what makes the system clean and flexible at household scale.
4. Composting Happens in Bristol
After fermentation, the material is:
-
composted under managed aerobic conditions
-
blended with local carbon sources
-
monitored for moisture, structure, and biology
We prioritise soil health over speed.
This allows diverse microbial communities to develop, producing compost that supports:
-
soil structure
-
water retention
-
microbial life
-
long-term fertility
All composting takes place within Bristol.
5. Compost Matures Into Living Soil Food
The compost is then matured until:
-
biological communities stabilise
-
nutrients become plant-available
-
the material is safe and effective to use
The result is living compost, not inert digestate.
It feeds soil life as well as plants.
6. Nutrients Return to Bristol Soil
Finished compost is returned to:
-
Community gardens
-
Allotments
-
Schools
-
Urban growing projects
-
Our food forest market garden
Members can:
-
Receive compost back
-
Donate compost locally
-
Support soil regeneration across the city
-
The loop is complete.
Why This System Works
This approach works because it is:
Local
Food waste never leaves Bristol.
Biological
Microorganisms do the work, not chemicals or extraction.
Clean
Fermentation prevents smells, flies, and mess at home.
Circular
Nutrients return to food-growing soils.
Transparent
You can see exactly where your food waste goes.
This isn’t waste disposal.
It’s soil building.
What This Means for Bristol
When household food waste stays local:
-
transport emissions are reduced
-
urban soils regain carbon and structure
-
water absorption improves, reducing flood risk
-
food growing becomes more resilient
-
people reconnect with natural cycles
Small actions, multiplied across a city, create real change.
