Most guides on this topic fall into one of two camps: composting evangelists who make it sound like every leaf and branch belongs in a bin, or removal companies who skip past composting entirely because it doesn’t lead to a booking. Neither is fully honest.
The truth is simpler: composting is genuinely the right answer for a lot of routine garden waste, and a bad fit for the rest. Here’s the honest version of what actually composts well at home, how Cape Town’s own composting programme works, and the point where a compost bin stops being the answer.
What Composts Well at Home (And What Doesn’t)
Composts Well
- Grass clippings and lawn cuttings
- Leaves
- Soft weeds — pulled before they’ve gone to seed
- Small, soft prunings and hedge trimmings
- Coffee grounds and tea leaves
- Eggshells
- Shredded cardboard and paper
Keep Out of the Bin
- Meat, dairy, or cooked food scraps
- Diseased or pest-infested plant material
- Invasive weeds or established root systems
- Large or woody branches
- Treated or painted timber
- Pet waste
If what you’re clearing is mostly the first list, composting is a genuinely good option, not just an eco-friendly consolation prize.
Cape Town’s Free Home Composting Programme
The City of Cape Town runs an official Home Composting Programme that provides residents with a free compost container. It’s worth knowing upfront that this rolls out area by area rather than being available on demand citywide, so whether you can get one right now partly depends on whether the programme has reached your part of the city yet.
To apply, you’ll need a signed application form (available on the City’s website in several languages), which you can email to wastewise@capetown.gov.za or drop off at your nearest subcouncil office or walk-in centre. You can also call the City’s Solid Waste call centre on 0860 103 089 to check where your area stands in the rollout.
It’s a genuinely useful programme for anyone doing routine garden maintenance: free equipment, official backing, and a lot less guesswork than building your own setup from scratch.
The Real Volume Limit of a Home Compost System
A compost bin or heap has a practical ceiling, and it’s lower than most people expect. Routine light garden maintenance a weekly mow, the odd hedge trim, and seasonal leaf fall fits comfortably within what a standard home bin can process in a normal cycle.
A full garden clear-out doesn’t. Neither does storm damage, a landscaping project, or anything that produces branches thicker than a finger. It’s not just a volume problem, either: woody material breaks down at a fundamentally different rate to grass and leaves, so even a modest pile of thicker branches can sit in a bin for a year or more without fully composting, effectively blocking the bin from doing anything else in the meantime.
If you’re regularly topping up a bin that’s already full, or watching a “temporary” pile of branches turn into a permanent one, that’s the system telling you it’s past its limit, not a sign you’re composting wrong.
When the Pile Outgrows Composting
- A full garden clear-out or a new landscaping job, where the volume alone exceeds what a bin cycles through in a reasonable time
- Storm damage or a tree-felling job, where the material is mostly thick branches and trunk sections rather than soft green waste
- A one-off big tidy-up after months of neglect, where the backlog is simply too large to compost through before more waste arrives
- Anything mixed with builder’s rubble, since sorting rubble out of a compost pile isn’t realistic
At that point, composting isn’t failing you; the job has just moved outside what a home system was ever designed for. Rather than let branches pile up for a year hoping they’ll eventually break down, it’s faster and more practical to get it collected instead and let your compost bin get back to doing what it’s actually good at: the routine stuff.
