Mixed plastics
For non-edible planters
Hard-to-recycle mixed plastic becomes sturdy ornamental and non-food planters — keeping material in use instead of in a dump.
South Africa · Recycled gardens
We turn plastic waste into growing systems.
PlastiGrow Systems converts mixed plastic into durable modular planters — so township households and schools can grow food in small spaces.
01
Schools
Courtyards and classroom walls become living gardens.
02
Communities
Township households grow food where space is tight.
03
NGOs
Durable kits for food and waste programmes that last.
04
Partners
Recyclers, funders, and local businesses building with us.
The problem
Two pressures, sitting side by side.
South Africa faces a plastic waste crisis and a food security challenge at the same time. PlastiGrow exists because those two problems can help solve each other.
- 01
Plastic that will not leave
Mixed plastic piles up in streets, dumps, and waterways. It lasts for decades and is hard to reuse as-is.
- 02
Food that does not reach the table
Many township households and schools want to grow food — but yards are small, soil is poor, and cheap pots crack in the sun.
Our solution
Modular gardens, made from the plastic already around us.
PlastiGrow turns waste plastic into vertical wall planters, raised beds, and stackable kits. They fit small yards, school walls, and courtyards — and they last.
Dual-material approach
We sort first, so the right plastic goes to the right garden.
HDPE and PP
For growing food
Safer plastics — mainly HDPE and PP — are reserved for planters used to grow vegetables, herbs, and other edible crops.
How it works
Four steps from waste to a working garden.
A simple loop: collect plastic, make planters, put them where food can grow, and keep using them.
-
01
Collect & sort
We work with communities, schools, and recyclers to gather mixed plastic waste, then sort it before anything is made.
-
02
Process
Plastic is cleaned and moulded into durable modular parts — the right polymer reserved for the right garden.
-
03
Assemble
Modules become vertical systems, raised beds, and stackable kits that fit the walls and yards people already have.
-
04
Grow
People plant, harvest, and reuse the same beds season after season.
Products
Planters made for small spaces and long use.
Three core products. Same idea: durable, modular, and made from recycled plastic.
Vertical Wall Planters
Grow up, not out. Pocket modules mount on walls, courtyards, and school buildings.
- Saves ground space
- Easy to water and harvest
- Fits existing walls
Raised Garden Beds
Sturdy beds that sit above poor or compacted soil — built to take sun, rain, and years of use.
Details
Stackable Kits
Start with one module. Add more as the garden — and the group — grows.

Pressures, one loop
Waste and food, treated as one problem.

Steps to a garden
Collect, process, assemble, grow.
03
Growing systems
Walls, raised beds, and stacks.

Impact
Waste out of the street. Food closer to home.
Every kit does two jobs: it keeps plastic in use, and it gives people a place to plant.
Environmental
Plastic is diverted from dumps and waterways and kept in use as garden infrastructure that lasts for years.
Youth jobs
Local sorting, moulding, and assembly are built to create skills and work for young people — close to the plastic and the gardens.
Food security
Households and schools grow food close to home. Learners see waste become something useful, with their own hands.
About
A simple idea, rooted in environmental science.
Sandile Sithole, a BSc Environmental Science graduate, started PlastiGrow Systems after seeing two problems sit side by side: plastic nobody wants, and families who want to grow food but have nowhere durable to plant.
Every school and township household that wants to grow food should have a garden bed that lasts.
