How food packaging waste challenges South Africa's zero waste to landfill ambitions
Globally, 1.05 billion tonnes of food go to waste, and in South Africa, almost 10.3 million tonnes of food go to waste annually, says the writer.

Sustainability has become the watchword for South African corporates, as they grapple with both the public's demand for environmentally friendly products and the demands of Environmental, Social and Governance (ESG) reporting.
However, this shift is now not only fostering collaboration between waste producers and managers to develop solutions that meet both environmental and regulatory expectations, but is also reshaping business practices for a more circular and responsible economy.
And it's not hard to understand why. Globally, 1.05 billion tonnes of food go to waste, and in South Africa, almost 10.3 million tonnes of food go to waste annually, however, the packaging that accompanies this waste has exacerbated the strain on our waste management systems.
As a result, to manage these numbers, companies are now examining business models that allow them to correctly move from the linear take-make-dispose model to a system that minimises waste, conserves energy and raw materials, and reintegrates excess back into the cycle – what has been termed the 'circular economy'.
At Interwaste, this principle is brought to life through practical, scalable solutions such as composting, which allows for the organic fraction of packaging waste — often tied to food disposal— to be diverted from landfill and transformed into nutrient-rich compost that feeds agricultural soils. In parallel, our Refuse Derived Fuel (RDF) technology enables the conversion of non-recyclable packaging waste into a fuel substitute used in industrial applications such as cement kilns, offering a valuable landfill alternative and reducing dependency on fossil fuels.
Additionally, given that in today's market, where consumer perceptions heavily influence brand value, demand is another key driver shaping packaging trends. In fact, according to research, consumers are willing to spend 9.7% more, on average, for sustainably produced or sourced goods, given that an astonishing 85% report experiencing first-hand the disruptive effects of climate change in their daily lives.

It's no surprise then that companies are using this type of data to drive innovative, sustainable packaging designs — incorporating biodegradable, compostable, and recyclable materials, as well as reusable systems that support a zero-waste-to-landfill approach.
However, if South Africa is to reach its zero waste to landfill goal by 2030, the reality is that 90% of waste from landfills must still be diverted correctly – and this means not merely just making use of recycling and reuse, by beneficiation technologies as well as, if we want to create value-adding opportunities which have the potential to create numerous environmental, social, and economic opportunities for South Africa.
Simply put, achieving a zero-waste, sustainable country starts with better management of waste at its source, supported by innovative solutions, as well as an effective recycling system and a widespread culture of responsible consumption.
And we need to start at a company level, where organisations examine their entire value chain to see how and where waste is created and therefore reduced, as well as where waste can be reused, recycled or repurposed.
This approach, when applied correctly, will not only divert a large amount of our waste from landfill disposal, but it also has the potential to create numerous environmental and social opportunities for South Africans, including economic ones.
While tackling food packaging waste requires navigating a complex web of environmental, economic, and social challenges, meaningful progress is within reach - if industry leaders, policymakers, and consumers unite behind bold, innovative action.
Certainly, as a waste management company, Interwaste is not just a participant in this process but a key driver of the transition to a truly circular economy, leveraging technologies like RDF and composting to turn waste into opportunity. We remain committed to delivering sustainable solutions that make a lasting impact.

Exploring the benefits of franchising: Insights from the Standard Bank Franchise Summit
Business franchise owners shared the benefits of different franchises at the Standard Bank Franchise Summit on Wednesday. Standard Bank Economic Insights believes that there is a positive outlook for the South African economy for franchises. Business franchise owners shared the benefits of different franchises at the Standard Bank Franchise Summit on Wednesday. Standard Bank Economic Insights believes that there is a positive outlook for the South African economy for franchises. Peter Moyanga, Franchisee Multi-store owner for McDonald's, said that he owns 18 McDonald's restaurants in Gauteng, Mpumalanga, Northern Cape, and the North West provinces. 'I employ more than 800 people who fall under the age of 18-35. There are advantages when you start a franchise business; this includes there being less risk vs starting a new business as you have something that is already successful.' Moyanga added that with a franchise, there is trademark and goodwill. 'The experience of business is also not a prerequisite for franchise business. I first had a dream of opening a restaurant while I was a student in 1981 when my uncle took me to a restaurant in Johannesburg. I started to do my research by reading and asking questions about what it means to open a restaurant business. I was determined to be a business owner, and for me, the key to this is passion, control, independence, achievement, growth, creativity, designation, and persistence.' Moyanga said that when he opened his first McDonald's store, he faced challenges as he had partners that were supposed to come on board, but unfortunately, they let him down. 'Lucky for me, it was Standard Bank that came on to assist me to be able to open McDonald's stores in South Africa. The cost of acquiring a franchise is much higher and more set and less flexible than, for example, when you open your own business. But that's the cost of being there. Franchisors need to be independent in their business. At my stores, we start our people right down at the bottom from high school, and we grow them. Other people in my business started with me 18 to 20 years ago, they're still there,' Moyanga said. Sheldon Tatchell, the founder of Legends Barber, said that he comes from a community called Eldorado Park in Johannesburg. 'This community, as you know, is inflicted with violent crime, and I learned the skill of barbering in my community at the age of 14 years old. Fast forward to 2011, I was working at a bank; however, I still dreamed of becoming a full-time barber. A dream that was really becoming a reality, but taking baby steps in the process. I can only remember that I had a clipper and a chair, nothing else.' Tatchell added that he would go on a scooter to customers, driving all over as a mobile barber. 'While riding on a scooter, I had this vision of a mobile bus, being fully equipped with all the steps needed to give haircuts. In 2013, I had a bus that made this services mobile. Two years later, there were 30 Legends shops across the country. We faced challenges during the COVID-19 pandemic in 2020, where the beauty industry was closed for four months. Legends Barbers relaunched in June 2020, and we have rebounded with over 75 stores in five countries.' Lee Langenhoven, Senior Manager, Economic Insights at Standard Bank South Africa, said that he believes that the South African economy is heading in the right direction. 'For the foreseeable future, there is a good chance that there could be another decrease in interest rates following last week's interest rate cut. I do think there could be most likely, probably with a 60% probability, another 25 basis points reduction, which would not necessarily come at the next meeting in July, but could maybe be put on hold until September. But I do think that 25 basis points would be the last one.' Langenhoven added that if you look at just spending patterns, across the economy, confidence seems to be returning. 'To a certain degree, certainly a little bit better than a year ago. If you look at growth in retail trade sales year on year, this is real, real growth. We see over the last few months that the price of retail sales grew at an excess of 7% towards the end of last year.' BUSINESS REPORT Visit:

Amid Scandals and Silence, Rheinmetall Expands in South Africa
Rheinmetall Denel Munition (RDM), the South African arms manufacturer jointly owned by Germany's Rheinmetall AG and South Africa's state-owned Denel, is expanding again. On June 2, Rheinmetall announced the formation of a new company: Rheinmetall Resonant, following the acquisition of a majority stake in local firm Resonant Holdings. In recent years, RDM has been at the centre of investigations, protests, and legal action over its role in exporting weapons to conflict zones. Much of the backlash stems from findings by Open Secrets, a South African civil society group, which previously documented how RDM-manufactured weapons were used in the Saudi-led war in Yemen. Critics argue that when Germany imposed export restrictions on Saudi Arabia over human rights concerns, Rheinmetall turned to its South African subsidiary as a loophole. With South Africa's arms regulations seen as more relaxed and oversight comparatively weaker, the company was able to continue supplying Gulf allies via RDM. This model of using foreign subsidiaries to bypass national restrictions has become a deliberate strategy. A report by Investigate Europe showed how Rheinmetall systematically relies on companies like RDM not just to manufacture weapons, but to build entire ammunition plants abroad often with limited transparency or scrutiny. This practice has raised serious concerns about how little control South African authorities exert over what happens to weapons once they leave the country. That concern surfaced again last year, when a major order of RDM's 155mm artillery shells destined for Poland was reportedly delayed over fears they might ultimately be sent to Ukraine. Although South Africa maintains a formal stance of neutrality in the Russia-Ukraine war, the incident raised uncomfortable questions about whether its arms industry is undermining that position. The most politically explosive allegations now involve Israel. Following the outbreak of war in Gaza, activists have warned that South African-made munitions may be reaching Israeli forces indirectly, through NATO or European allies. While there is no confirmed evidence of direct sales to Israel, arms shipped to Germany or Poland could be passed on through defence cooperation agreements. The possibility alone has caused public outrage, especially given that South Africa has filed a genocide case against Israel at the International Court of Justice. The Economic Freedom Fighters (EFF) have taken the lead in demanding accountability. Speaking on behalf of the party, Carl Niehaus accused the government of hypocrisy and called for a full inquiry into all RDM exports. He said South Africa cannot condemn Israel on the international stage while indirectly supporting its military through unchecked arms flows. He urged the government to shut down what he called a 'back door' route for weapons. Civil society organisations argue that South Africa's arms control system is outdated and effectively powerless. Once weapons are shipped, they say, authorities rely too heavily on end-user certificates—paper guarantees that mean little in practice, especially during war. Without transparent tracking or independent verification, the entire system rests on trust in a global industry notorious for secrecy and loopholes. Despite mounting concerns, Rheinmetall is tightening its grip on South Africa's defence sector. The launch of Rheinmetall Resonant underscores the company's confidence in using South Africa as a key manufacturing hub. But the expansion comes with no answers to deeper questions: is South Africa becoming a passive accomplice to foreign wars it publicly opposes? And who, exactly, is watching? As factories continue operating and new contracts are signed, the South African public is still waiting for clarity. According to a recent report by IOL, the National Conventional Arms Control Committee (NCACC) has yet to respond to formal requests from the EFF for an investigation into RDM's factory and the potential routes its shells may be taking. The silence, critics argue, is only deepening the trust gap.

China and South Africa deepen economic cooperation through trade initiatives
Strengthening ties: China and South Africa enhance cooperation through trade and investment Strengthening ties: China and South Africa enhance cooperation through trade and investment With China increasing its engagement in Africa, collaboration between China and South Africa is continuing to transforming trade, investment, and economic cooperation for both nations. This week, the Daily News was granted an exclusive insight from the Chinese Consul General in Durban Li Zhigong who shed light on vast opportunities waiting to be tapped into between both nation nations. In the interview with Zhigong, praised the the burgeoning partnership between China and South Africa. The Consulate General highlighted that he was taking firm steps to promote bilateral trade and investment, especially within KwaZulu-Natal, an area rapidly gaining recognition as a gateway for Chinese investment into the region. By facilitating business delegations, organising matchmaking events, and supporting trade expos, the consulate plays a pivotal role in creating fertile ground for both South African and Chinese businesses. Zhigong highlighted that major Chinese companies, including YOA Cabel, ZPMC, and NPC, have already made significant investments in the province. Their contributions not only boost the local economy but also forge deeper economic ties between China and South Africa. For South African businesses eager to tap into the vast Chinese market, the Consul General underscored the importance of leveraging existing bilateral trade agreements. He pointed out that events like the China International Import Expo (CIE) act as vital platforms for showcasing South African products, particularly wine, which has found a warm reception among Chinese consumers. Additionally, the recent opening of the Chinese market to South African avocados and soybeans marks a significant opportunity for producers in the region. Zhigong emphasised that provinces such as Guangdong, Fujian, and Guangxi—which are sister provinces to KwaZulu-Natal—regularly host trade fairs that encourage economic collaboration. He added that prospects in sectors like the digital economy, green energy, and advanced manufacturing continue to increment the appeal of the Chinese market for South African enterprises. These industries not only promise growth but also offer a diverse array of opportunities for collaboration. "Provinces like Guangdong, Fujian, and Guangxi—KwaZulu Natal's sister provinces—regularly host trade fairs and economic forums that provide platforms for cooperation. For example, the China- ASEAN Expo in Guangxi also highlights African participation. With opportunities in digital economy, green energy, and advanced manufacturing, China offers South African companies a growing and diversified market," he explained. In conclusion, the Belt and Road Initiative (BRI) has also emerged as a cornerstone in the framework of this evolving relationship. Zhigong detailed how the BRI enhances economic ties by promoting essential infrastructure development and facilitating trade, as well as encouraging people-to-people connectivity. In addition, various logistics and energy projects aligned with the BRI are already making a tangible difference in South Africa, integrating with the country's national development goals and promoting sustainable cooperation that benefits both nations, he explained.
