Plastic Collection & Buy-Back
We buy post-consumer and post-industrial plastics from material recovery facilities (MRFs), hotels, factories and estates across Nairobi and surrounding counties, paying fair rates per kilo.

Waste in. Value out.
We collect and process used PET, HDPE, LDPE and PP plastics into clean flakes, granules and PET strapping — and turn sawdust and organic waste into high-heat charcoal briquettes.

What We Do
Full-circle recycling services
From collection and sorting to washing, shredding and extrusion — we handle every stage of the loop right here in Nairobi.
PET Flake Production
Bottles are de-labelled, washed, cold and hot-washed and crushed into clean, low-moisture PET flakes suitable for fibre, sheet and strapping manufacturers.
HDPE, LDPE & PP Granulation
Rigid containers, films and crates are shredded and extruded into consistent granules and regrind with controlled melt flow for injection and blow moulding.
PET Strapping Manufacturing
We produce high-tensile PET strapping from recycled flake — a strong, rust-free alternative to steel banding for pallets, bricks and timber loads.
Charcoal Briquette Production
Sawdust and organic waste are carbonised and pressed into dense, long-burning briquettes — a cleaner, smokeless fuel for homes, schools and restaurants.
Commercial Waste Contracts
Scheduled collection and recycling reporting for manufacturers, malls and offices that need verifiable diversion-from-landfill figures.
Our Story
Built in Nairobi, for Nairobi's waste stream
Karsam evolved with a simple observation: too much valuable plastic was ending up in Kenyan landfills and rivers while local manufacturers imported virgin resin at rising cost.
Today we operate a washing, shredding and extrusion line in Nairobi that converts PET, HDPE, LDPE and PP into clean flakes, granules and PET strapping. Alongside the plastics line, we carbonise sawdust and organic waste from timber yards and markets into charcoal briquettes.
We work directly with waste pickers, aggregators and industrial partners from all the 47 counties — creating income for collectors while giving manufacturers a reliable, locally produced recycled feedstock.

How It Works
From kerbside to feedstock
Four straightforward stages that turn mixed waste into a dependable industrial raw material.
Collect
We pick up baled plastic and sawdust from collectors, estates, factories and timber yards on a scheduled route.
Sort & Wash
Material is separated by polymer type, de-labelled, then cold and hot washed to remove dirt, glue and caps.
Shred & Extrude
Clean plastic is shredded into flakes or melted and extruded into uniform granules and PET strapping.
Deliver
Finished flakes, granules, strapping and briquettes are bagged and delivered to manufacturers countrywide and across the world
Client Voices
Trusted by manufacturers and collectors
We measure success by repeat orders and by the tonnes we keep out of landfill.
GreenLoop's PET flake is consistently clean and dry. We've cut our virgin resin use by nearly a third since switching, and the quality has never dipped.
Peter M.Production Manager, Fibre & Yarn Ltd — Athi River
Their briquettes burn longer than the charcoal we used before and there's far less smoke in the kitchen. Our fuel bill dropped noticeably.

I've sold plastic to GreenLoop for four years. They weigh fairly, pay on time, and the collection team is always professional.
