# Kubik: Building Brick by Brick with Plastic Waste

According to the [Organization for Economic Co-operation and Development](https://www.oecd.org/en/about/news/press-releases/2022/06/global-plastic-waste-set-to-almost-triple-by-2060.html)
 (OECD), the amount of plastic waste produced worldwide is expected to triple to more than 1,000 million tons by 2060. It is estimated that developed countries will continue to generate the most plastic waste per person.

Still, regions such as Africa and Asia are expected to see the fastest growth due to rapid population growth and urbanization. Even so, African startups have embraced and integrated green technologies to mitigate climate change and reduce carbon footprints.

## A Standout in East Africa’s Green Technology Sector

[Kubik](https://www.buildkubik.com/)
, headquartered in Addis Ababa, Ethiopia, is an environmental technology company that transforms plastic waste into affordable, low-carbon building materials. Founded in 2021 by Kidus Asfaw, Kubik is a key standout in the region’s green technology sector. Their mission to combat climate change and reduce construction carbon footprints aims to help solve Ethiopia’s housing crisis. They are tackling these problems by producing plastic construction bricks from hard-to-recycle plastics. Kubik is combining positive social impact, circular-economy principles, and low-carbon construction as scalable solutions to the region’s most pressing challenges, such as the affordable-housing shortage and plastic-waste management.

## **Transforming Plastic Waste to Structural Goods**

The startup technology involves converting difficult-to-recycle plastic waste, like polyethylene, polypropylene, and polystyrene, into durable, structural building materials. Though their source stream requirements are not public, some possibilities may come from household durable goods, automotive components, electrical housing, and possibly previous structural construction components.

The structural construction components engineered by Kubik produce an interlocking system. This enables fast, affordable assemblies with an average 40% cost savings compared to commonly used masonry techniques. Developers can construct walls without the traditionally required cement, aggregates, and steel. This is all possible without compromising structural integrity while matching cement-based structures, according to a [TechCrunch interview with Asfaw](https://techcrunch.com/2023/06/22/kubik/)
. Additionally, Asfaw explains that bricks, columns, and beams are designed with chemical properties that make them safe to use, providing both flame resistance and long‑term durability without degradation. From a sustainability perspective, they enable about 45,000 kg of plastic waste per day to be repurposed by local communities. Furthermore, Kubik’s plastics components produce lower carbon emissions by five times compared to traditional cement-based blocks.

Although Kubik keeps its manufacturing process proprietary, Asfaw outlined several key production steps in an interview with [Connecting Africa](https://www.connectingafrica.com/innovation-hub/hot-startup-of-the-month-ethiopia-s-kubik)
. Kubik begins by collecting and sorting plastic waste. The team then cleans the plastics and inspects them for contamination and debris before processing them further. Through a partnership with the City of Addis Ababa, Kubik sends the cleaned and sorted plastics to its Ethiopian factory in Adama Industrial Park. There, the company uses its proprietary extrusion-based upcycling technology to melt and reform the material into structural components such as bricks, beams, panels, and columns. Kubik then shapes the recycled plastic into high-quality, interlocking building pieces designed for fast assembly and structural strength. The company supports its manufacturing and supply chain operations through local employment opportunities, which help strengthen surrounding communities.
