Natural capital

We apply our resources and technology to convert natural capital into value across all the other capitals. Reliable supplies of water, energy, land and air are critical to the success of our business. We also depend on a consistent supply of limestone, silica sand and soda ash for the manufacture of glass packaging.

We strive to reduce the impact of post-consumer packaging waste on landfills and are committed to encouraging recycling and further reducing the weight of our packaging products. We adhere to well-defined environmental and producer responsibility standards.

Trade-offs in our use of natural capital

Our use of non-renewable resources such as limestone, silica sand and soda ash, as well as our emissions and wastes, negatively impacts natural capital. But by converting natural capital into value-added products, we boost the stocks of all the other capitals. The use of cullet in our glass business and closed-loop raw material systems in our plastics operations positively impacts natural capital. We continue to explore other ways of limiting our impact on the natural environment.

HOW WE ACHIEVED THESE OUTPUTS AND OUTCOMES

  • Continued to promote recycling initiatives – all Nampak products are recyclable
  • Installed gas line at our Glass operation
  • Submitted preliminary carbon budget to South African government
  • Utilised borehole water at our Zambian operations in Lusaka and Ndola and at Agbara in Nigeria
  • Participated in establishing MetPac-SA which will promote the recycling of metal packaging
  • Secured, by way of contract, the supply of all raw materials to Glass
  • Unpredictable power supply, with volatility of voltage, to Glass disrupted operations
   

NATURAL CAPITAL FOCUS: RECYCLE, RECYCLE, RECYCLE

     
   

We are committed to ensuring that Nampak is an environmentally responsible company and believe that integrated actions that we take within our operations to conserve natural resources and protect the environment make sound business sense.

   

Recycling of post-consumer packaging waste is one of the initiatives we use to make a positive contribution to the environment in which we operate. Many of these initiatives are done in conjunction with other packaging companies and industry bodies.

We hold a 25% share of the glass packaging market in South Africa and through our association with The Glass Recycling Company we have contributed to increasing the recycling rate of glass from 18% 10 years ago to 41% in the 2016 calendar year. During this time, 50 000 income opportunities and 263 entrepreneurs were created. Our usage of cullet, or waste glass, in 2017 was 63 000 tonnes and represented 54% of the final production.

In 2016, 1.144 million tonnes of post-consumer recyclables were available in the waste stream and 47% of plastics packaging was collected for recycling, 6% more than in 2015. This is equivalent to 374 million 2 litre milk bottles. South Africa mechanically recycled 309 520 tonnes of plastic in 2016, an increase of 6% from 2015. A total of 329 099 tonnes of plastic were diverted from landfill in 2016; 6% more than 2015.

Collect-a-Can was established as a joint venture over 20 years ago to collect used beverage cans and during this time it has increased the collection rate to 72%, which is one of the highest in the world. In 2017 we participated in the establishment of MetPac-SA to promote recycling of other metal packaging.
