This World Water Day Act Against Marine Pollution

This World Water Day Act Against Marine Pollution

The time to act against marine pollution is today, March 22 and World Water Day 2017; tomorrow will be too late.

This is the opinion of South African National Bottled Water Association executive director, Charlotte Metcalf, who points to statistics quoted by organisations like Greenpeace and the World Wildlife Fund to highlight the dangerous levels of marine pollution and who, together with her member bottlers, are striving for responsible corporate citizenship.

The bottled water industry is a relatively small user of PET; estimates put its usage at less than 5%. Please refer to Plastics|SA3 and PETCO4 for specific figures regarding plastic usage and recycling.

World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.

An international day to celebrate freshwater was recommended at the 1992 United Nations Conference on Environment and Development (UNCED). The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day.

Acknowledging that World Water Day highlights a specific aspect of freshwater, Metcalf nevertheless stresses that marine water resources are under equal threat and highly polluted.

According to National Geographic, pollution is “the introduction of harmful contaminants that are outside the norm for a given ecosystem. Common man-made pollutants that reach the ocean include pesticides, herbicides, chemical fertilizers, detergents, oil, sewage, plastics, and other solids.”

“Several sources – including the National Ocean Service ( – say that over 80% of marine pollution comes from land-based activities. From plastic bags to pesticides – most of the waste we produce on land eventually reaches the oceans, either through deliberate dumping or from run-off through drains and rivers,” she said.

“As an industry that utilises plastic and glass, the bottled water industry in South Africa is very concerned with the solid rubbish that makes its way to the ocean. Plastic bags, balloons, glass bottles, shoes, packaging material – if not disposed of correctly, almost everything we throw away can reach the sea.

“SANBWA therefore acknowledges, respects and supports all attempts to draw attention to the pollution of the earth’s marine resources but also urges that humans – as individuals, communities, governments, and corporations and other organisations – have a major role to play in curtailing this pollution.

“If we humans dramatically changed our behaviour so that we don’t litter, we recycled as much of our waste as possible and, in our positions of power such as politicians and directors of companies, our took decisions that did not have far-reaching negative consequences for the world’s health (such as dumping hazardous waste, for example) – it would have a significant positive impact on levels of pollution,” she said.

As a responsible corporate citizen, SANBWA is making certain its members play their part in reducing plastic waste, and is able to stand side-by-side with organisations like Greenpeace when they highlight where society is falling short in theirs.

Metcalf explained: “SANBWA was formed in 1997. Its members’ primary concern is the health, safety and pleasure of their consumers. They therefore willingly conform to the extremely stringent safety and quality measures contained in the SANBWA Bottled Water Standard1, which includes environmental stewardship2.

“These environmental stewardship protocols address measures to ensure source sustainability and protection, water usage minimisation, energy efficiency, solid waste minimisation, and support post-consumer recycling initiatives.

“In addition, as an organisation, SANBWA was among the first worldwide to require its members to follow specific recycling guidelines. In this respect, it was advised by PETCO in South Africa (the local plastic industry’s first joint effort to self-regulate post-consumer PET recycling).

“In this respect, it expects members to only support PET bottle suppliers which contribute to the PETCO recycling levy; establish a drop-off centre for the public at the bottling facility and all distribution centres; add the ‘please recycle’ sign on all labels; and use recycling friendly materials or recycling optimal materials as stipulated in the SANBWA Bottled Water Standard or on

“PETCO are currently fine-tuning a ‘design for recycling grading system’ which SANBWA fully supports to ensure that members’ packaging is easy to recycle and does not end up on landfill because of one small component – the type of glue used to fix the label, for example – that is undesirable for the recyclers’ process and therefore rejected.

“Importantly, SANBWA formally audits its members’ compliance with respect to environmental stewardship. It will soon also audit non-members, and inform these bottlers when or if they find any shortfalls in their packaging, and suggests changes. Bottled water bottlers – whether they are SANBWA members or not – must remember that extended producer responsibility is a legal requirement for doing business in South Africa.

“Finally, SANBWA also regularly reminds consumers of the need to manage their litter and recycle. This is achieved through media releases like these as well as supporting relevant international events (such as International Coastal Clean-Up Week), and sharing notice of and success of initiatives on its social media channels.

“SANBWA’s key message is a dual one: ‘Water — in all its forms — is a vital component of our diet, as well as the healthiest beverage option for societies plagued by diseases such as obesity and diabetes.

“When tap water is unavailable or unsafe to consume, bottled water is the best packaged beverage option for the environment; it has the lightest environmental footprint of all packaged beverages — one that can be reduced by 25% if consumers were to simply recycle the bottle,” Metcalf concluded.


1. A single standard covering legal, hygiene, food safety and quality, and environmental requirements, the SANBWA Bottled Water Standard benchmarks favourably against international standards and:
• ensures legal compliance
• is fully auditable so that a single audit can ensure that all legal and food safety requirements have been met thereby protecting the bottler and enabling it to prove due diligence
• helps bottlers identify the area where they still need to improve
• assists retailers and consumers to select suppliers of safe bottled water

Cost of membership includes commissioning of a range of independent specialists to certify members conform to very strict standards of quality, safety and efficiency of manufacture. Membership is only granted after all critical requirements have been met, including displaying specific information on their product labels for the consumer’s benefit. In addition, a pre-requisite for membership is certification by a professional hydrogeologist that the water source is safe and free from existing or potential pollution. This ensures a long term permanently safe source of raw material for natural spring or mineral water.

2. SANBWA’s environmental vision is to improve members’ environmental stewardship. It covers four critical areas:
• Water. Ensuring effective water management from source to shelf, including requirements for source protection, efficient water usage and responsible effluent practices.
• Solid waste: Reducing, re-using, recycling all solids involved in the production and distribution of their products.
• Energy: Promoting the efficient use of energy and fuels.
• Post-distribution recycling: Supporting municipal and consumer initiatives for recycling packaging and bottles.

Bottled water companies are reducing their environmental footprint by using lighter weight plastics. Bottles currently weigh 27% less than they did seven years ago. The bottles, made from PET, a by-product from oil-manufacture, are 100% recyclable. Alternative packaging solutions, such as recycled content, are also being developed and used. The bottled water industry financially supports comprehensive recycling programs and partners with the recycling industry such as PETCO. SANBWA also requires members to use recycling friendly materials in their packaging material.

3. Over the last couple of decades, Plastics|SA – the umbrella organisation representing the local plastics industry – has been measuring the recycling rate of plastics in South Africa. Below are the top line findings for the year ending December 2015.
• South Africa mechanically recycled 292 917 tons of plastics in 2015 – an increase of 3 % year on year from 2014.
• Over the last 5 years the compounded growth in plastics recycling was 5.5 % per annum.
• Domestic production of virgin polymers totalled 1 490 000 tons in 2015, growing 6,4 % from 2014. This growth would essentially be as a result of the weakening exchange rate against international currencies that lead to local procurement of plastics products rather than imports.
• A total of 310 641 tons of plastics were diverted from landfill in 2015. This is 1.6 % less than in 2014 and is due to the significant reduction in the export of recyclable waste.
• The overall diversion from landfill rate was 20.8 % – decreasing from 22.5 % in 2014.
• Strong growth was seen in the recycling of PET, PE-LD/LLD and PS due to new capacities that came on line in 2015.
• Recycling rates of PE-HD, PP and PVC declined as some of the products traditionally made from recyclate of these materials are directly linked to consumer spending and mining activities.
• Formal employment in the recycling sector increased with 3.3 % to 6 234 permanent jobs. Informal employment has grown with 3 % to an estimated 48 820 collectors.
• The recycling industry invested 48 % more in capital equipment per ton of material processed in 2015 to deal with increasing demands and improved quality requirements.
• Processing costs increased 15.4 % year on year with the biggest contributors to cost being water, electricity and transport.

4. Recycling update – PET

PETCO was formed 12 years ago as an industry-driven and financed environmental solution for PET. It is responsible for managing the PET industry’s extended producer responsibility (EPR) in South Africa. These are its key figures for 2015, updated in April 2016:
• Local market consumption* – 210 000 tonnes
• Bottle market – 68%
• Bottle market size (excluding edible oil) – 142 800 tonnes
• Post-consumer tonnes bottles recycled – 73 710 tonnes
• Post- consumer bottle recycling rate – 52%
• Bottle recycling rate including pre-consumer – 54%
• Total PET market recycling rate (including pre-cons, edible oil and sheet) – 37%
• Year-on-year growth: total PET market – 8.5%
• Year-on-year growth: recycled tonnage – 15%
• Tonnes exported: bottles and flake – 6 777 tonnes
• Bottles recycled in 2015 – 1.7 billion
• Bottles recycled per day in 2015 – 4.7million
• Income opportunities** – 50 000
• Carbon saved – 110 000 tonnes
• Landfill saved – 460 000 m3

* (Virgin and rPET used in packaging, excludes only packaged imports)
** (Formula: 1 income opportunity equates to one waste picker collecting 200 bottles per day for 240 days per year. One tonne contains 33 000 bottles)
