Introduction
Section 1 of Develop Your English focuses on the ways that we produce and consume things and how this affects the environment. In this Unit you’ll learn about the problems caused by consumer waste, particularly plastics, and find out about some innovative ways of dealing with plastic waste as part of a circular economy. A circular economy is a less wasteful one, and you’ll learn more about how it works in the listening. Read the quote and the text on the image before you go any further.
‘Circularity transforms our throwaway economy into one where we eliminate waste, circulate resources, and adopt nature-positive, low carbon, resource-efficient systems and actions.’

Reading – African digital innovators are turning plastic waste into value – but there are gaps
Before you read – Give your opinion
- Every year more than 12 million tonnes of plastic end up in the world’s oceans, and although a significant proportion of that waste is produced in developed, industrialised countries much of it ends up on the shores of African countries, whose citizens then have to find ways to deal with it.
- When macroplastics degrade into microplastics (tiny particles of plastic smaller than 5mm) they are eaten by marine animals, which contaminates the food chain and poses threats to human health.
Collocations
There are 6 common collocations, or word partnerships, with the word plastic in the text.

African digital innovators are turning plastic waste into value – but there are gaps
Dr. Seun Kolade, Professor of Entrepreneurship and Digital Transformation, Sheffield Business School, UK, and Dr. Muyiwa Oyinlola, Associate Professor, De Montfort University, UK
Plastic pollution is a growing global menace. Between 2010 and 2020, the global production of plastics increased from 270 million tonnes to 367 million tonnes. Every year, more than 12 million tonnes of plastics end up in the world’s oceans, with severe consequences for marine life. When macroplastics degrade into microplastics, they easily contaminate the food chain and pose significant threats to human health via inhalation and ingestion.
By 2030, plastic waste is expected to double to 165 million tonnes in African countries. Most of this will be in Egypt, Nigeria, South Africa, Algeria, Morocco and Tunisia.
A significant proportion of the plastic that ends up on African shores is produced in developed, industrialised countries. By 2010, it was estimated that close to 4.4 million tonnes of mismanaged plastic waste was in oceans and seas off the coast of Africa every year. A 2022 estimate has put this number at 17 million tonnes.
Growing numbers of NGOs and innovators across the continent are responding to the challenge. They are developing digital solutions to reduce plastic waste generation, and promoting reuse and recycling of plastic products. Increasingly, African tech hubs are incorporating environmental sustainability in their business models.
In our recent paper, we highlight ongoing efforts and innovations in what is called the plastic value chain. This comprises four phases, from the design of plastic products to manufacture, use, and end of life.
We found a number of initiatives that are transforming the plastic value chain into a smart, innovative and sustainable network. Most aim to improve plastic identification, collection, transport, sorting, processing and reuse. Some focus on the earlier phases: design and production of plastic products.
A whole value chain approach to the circular plastic economy is very important. While the majority of plastic waste management activities tend to focus on the use and end-of-life phases, more attention needs to be given to design and manufacture. This is where the problem of plastic waste begins.
Worldwide, attention is turning to designing simpler and standardised products that are easier to recycle and reuse.
Innovators cracking the code
A Nigerian software company, Wecyclers, operates a rewards-for-recycling platform. It offers incentives to individuals and households in low-income communities to make money and capture value from recyclable plastic waste.
Via the platform, waste collectors are connected to a fleet of locally assembled waste cargo vehicles. They use these to collect waste from subscribing households. These households are also rewarded according to the quantity of waste collected from them.
The collected waste is deposited in designated locations in the Lagos metropolis, to be collected in bulk by recyclers. This provides materials to manufacturers who turn it into new items like tissue paper, stuffing for bedding, plastic furniture, aluminium sheets and nylon bags.
The impact is significant on many levels. Firstly, by linking waste generating households with waste collectors in their neighbourhoods, the Wecycler model simplifies the logistics of collection and sorting at source, at practically no cost to households. Secondly, it enables households not only to mitigate the public health risks associated with plastic waste accumulation and mismanagement, but also to generate income. Finally, it elongates the end-of-life phase in the plastic value chain through recycling and potential reuse.
In Uganda, Yo Waste, a technology start-up, has developed a mobile, cloud-based solution that connects waste generators to the nearest waste haulers in their community. Yo Waste improves the efficiency of scheduling and waste collection. It also helps waste collection companies measure the productivity of their trucks, and gives recyclers easier access to the plastic waste.
In Zambia, Recyclebot is connecting waste sellers to waste buyers via a crowdsourcing platform that aggregates waste by type and location. In effect, the plastic waste producers dispose of their waste for free, and waste buyers overcome the cost of separation, transfer and storage.
While these are promising innovations, the main challenge is scaling. This is slow on the continent. Start-ups in the recycling industry face additional challenges like inadequate funding and an under-developed plastic market that offers limited opportunities for growth and income generation.
A significant proportion of the funds accessed by start-ups is provided as grants from international and local organisations. Pure business investments are rare, and policy interventions are way behind the curve.
What can be done
To accelerate the transition to a circular plastic economy, stakeholders from across a spectrum of organisations must work together. They include NGOs, cooperatives, think tanks and community groups. The current approach to tackle plastic waste on the continent remains scattered and inadequately co-ordinated. While efforts are being made to develop new ecosystems in many countries, key stakeholders are often missing.
In particular, African governments have a key role to play. They need to commit more to strategic investment in infrastructure, incentives and support for start-ups. African countries also need policy interventions to grow the market for circular plastic products at national and continent-wide levels.
In another study, we argued that innovators must tailor their strategies to create innovations that are functional and easy to use. This will make it easier for ordinary consumers and the general public to accept them. In turn it will help change habits of consumption and expand the market for circular plastic products.
Digital innovators, as early adopters, are critical for driving changes in the way the plastics economy works across the continent. Their innovations are also leading to knowledge exchange and cross-sectoral collaborations.
However, they also face significant institutional challenges and infrastructural limitations that are slowing down the pace of progress. By working together and pooling resources, stakeholders can achieve an impact that is much greater than the sum of their individual initiatives and contributions towards a circular plastic economy in Africa.

Function – Causality
The text (‘African digital innovators are turning plastic waste into value – but there are gaps’) shows us many links between plastic pollution and the health of humans and marine life. For example, when macroplastics degrade into microplastics, they cause a threat to human health via inhalation and ingestion.
Focus on causality
Here are some constructions that describe causality – when one thing (X) causes or affects another thing (Y):
- X causes Y
- X may result in Y
- X can give rise to Y
- X is a consequence of Y
- X is a key factor in Y
- X is a major influence on Y
e.g. When macroplastics degrade into microplastics (X), they cause a threat to human health (Y) via inhalation and ingestion.

Before you listen
In this listening Ana Mestre, a Research Fellow in Design at Nottingham Trent University UK, explains why a big shift is needed in the way that the stuff we buy is designed so that it can either last a lot longer, or be biodegradable (able to be changed by the action of bacteria to a natural state that will not harm the environment).
- ‘Waste not, want not’ is a proverb that means if you use a resource carefully and without extravagance (waste not) you will never be in need (want not). Do you have a similar saying in your home language?
- Mestre says that many of us are buying a lot of stuff that we’re not very good at reusing or recycling – even when we think we care about the environment. Is over-consumption possible in your local context? Is recycling an option? If yes, is this something you do?
- Mestre describes the ‘linear’ economy, and the ‘circular’ economy. Guess if this example from the listening is a description of the way that the linear economy or the circular economy works:
‘You buy a washing machine, use it for a few years until it breaks, throw it away and buy a new one’.
- Look at the word cloud created from the transcript. The most frequently used words are: use (7), think (6), economy (6), product (5), waste (5), circular (5). (‘Actually’ is a filler word that Mestre uses, rather than a topic word). With the title in mind (Waste Not, Want Not) create a sentence that uses as many of these words as possible that predicts the main point of the listening.

Vocabulary – Responsible consumption and production
Writing
In this Unit you’ve learned about the ways African innovators are dealing with plastic waste as part of a circular economy. Jade Sarah Joven Suren’s story continues this theme. Jade lives in the city of Manila in the Philippines.
Read Jade’s story and write a response to it that incorporates what you know about the circular economy, and SDG12 Responsible Consumption and Production. Write about:
- What Jade and the Women Waste Warriors do, and why it is important.
- How the circular economy functions in Jade’s context.
- Why repurposing plastic waste is important.
- Why we need to think about consumption and production patterns.
- Any similar initiatives that you are aware of in your own context or elsewhere.
- Any other topic relevant to the circular economy or SDG12.
Turning Plastic to Profit
“Before, I used to just lay around the house and do house chores. Now, I am productive, I am able to earn a little even if I don’t have a job,” says Jade Sarah Joven Suren, a mother of one, who tries to augment her husband’s income as a cable TV agent and barangay (village) secretary. “More than that, I learn new skills and get to enhance my knowledge. I also get to bond with other women in the community.”
Jade is a member of Women Waste Warriors (3Ws) from Barangay 412 in Sampaloc, Manila. 3Ws is a community-based organisation promoting proper waste management within their homes and community and to explore alternative reduce, reuse, recycle (3Rs)-related livelihood projects. Jade is often working with other women, spending most of their day at the barangay daycare centre. In a busy week, they would repurpose PET bottles into 5,000 urban gardening pots to be supplied to the Philippine Council for Agricultural, Aquatic, and Natural Resources Research and Development.
To support their work, another group of warriors drives around different barangays to source used PET bottles from junk shops. It is estimated that 50kg to 100kg of plastic are diverted away from sanitary landfills every week.

Speaking – In your local context…
Read the summary and discuss the questions below:
SDG12 Summary
Sustainable growth and development require minimising the natural resources and toxic materials used, and the waste and pollutants generated, throughout the entire production and consumption process. SDG 12 encourages more sustainable consumption and production patterns through various measures, including specific policies and international agreements on the management of materials that are toxic to the environment.
