Eco-friendly – Environment - Greener options – Reduced Carbon footprint... Companies are under continuous pressure to improve the triple bottom line. One method of measuring the environmental impact of the plastics industry, and in particular the plastics packaging industry is to track the recycling rate of its products. Over the last few decades, Plastics|SA measured the recycling rate of plastics in South Africa. The last comprehensive and complete survey was done for 2009. Annual updates are done to measure the trends in recycling. This report is for the recycling rates of 2012.
Production data for the period has been collected from 59 recyclers representing 54% of the tonnages recorded in 2011. The recyclers ranged from very large to medium to small with regards annual tonnages. The 2012 figures in this report were arrived at by:
The PETCO published figure for 2012 has been used for PET.
It is estimated that there were more than 210 recyclers active in 2012. Nineteen companies recorded in 2011 were no longer operational. Thirty two recyclers entered the recycling industry just before, or during 2012, the bulk of which are waste management companies and collectors that have vertically integrated with granulators and pelletising extruders, with or without wash lines.

consumption of virgin polymer grew 5.4% in the same period to a total of 1370 ktons. It was noted that the export of waste plastics increased to 14 744 tons during the same period and if this is also taken into account, the total tonnages of plastics waste diverted from landfill equals 20.7% of all plastics manufactured in 2012. The local recycling rate was 19.6%.
Plastics packaging is contributing to visible litter and the plastics industry participated with other packaging role players in submitting the Paper and Packaging Industry Waste Management Plan to the Department of Environmental Affairs in 2011. In 2012, a total of 204 400 tons of packaging was recycled. This is an increase of 8.5% from 2011. Exports of plastics packaging waste increased more than 51% from 8 294 tons in 2011 to 12 532 tons in 2012. Therefore, plastics packaging waste diverted from landfill totalled 216 932 tons in 2012.
The plastics industry is slightly ahead of the estimated tonnages as well as the recovery rate, as per the Industry Waste Management Plan. The total plastics packaging in the waste stream for 2012 was 647 244 tons and the packaging recovery rate is 33.5% versus the 31.9% in the Waste Plan.
Plastics packaging includes products made from PE-LD, PE-LLD, PE-HD, PP, PET and PS with small volumes made from rigid and flexible PVC, ABS and E/VAL. Some bottle closures have inserts of E/VAL which is recycled.
According to BMI Research
Note: Recovery refers to the total tonnages diverted from landfill and includes exported packaging waste versus
Recycling that only refers to material that is mechanically recycled locally.
For the first time, there is a negative growth rate in the packaging not recycled: the amount of packaging sent to landfill in 2012 was 0.6% less than in 2011. With Separation at Source projects developing in the major metropolitan areas, this reduction in packaging waste to landfill can be maintained only where domestic solid waste can be accessed.

The total tonnage recycled is made up of a number of different materials, i.e. different polymer groups. The largest group is PE-LD and PE-LLD. They are grouped together for recycling statistics as only a handful of recyclers separate them prior to recycling and then only where it is applicable to factory waste. A total of 98 971 tons of PE-LD were recycled in 2012. This is made up of film waste and a much smaller quantity of irrigation pipe waste. Recycled PE-LD waste is sold back into the film industry, i.e. 66.5%, with 14% into the irrigation pipe market. The “other” portion is made up of some exports, masterbatch manufacturing, fencing droppers and rotational moulding powders.
Of all the materials, PP showed the largest growth in the last year. PP recycling grew with 17% to a total of 47 080 tons in 2012. The PP waste is sourced from injection and thermoformed packaging like closures, yogurt-and margarine tubs. The demand for non-packaging recyclable waste like garden furniture and automotive bumpers is growing. A few years ago, woven bags and metallised film were regarded as non-recyclable. Today there are more than 10 recyclers nationally that recycle these PP film grades with large success.
Recycled PP is mainly (83%) sold into the injection moulding market with chairs being the most popular single item. Exports make up a large portion of the PP recyclate as well. The relative small trader market for recyclate PP is popular amongst the very small recyclers as they pay cash and can blend poor quality material with better material to ensure customer satisfaction.
The demand for PP is exceeding the supply by magnitudes but the customers and potential customers do not want to pay more than roughly50% of virgin prices for recycled PP. There are various possible reasons for the recyclate price ceiling:
Market related, i.e. demand related, prices will have to be paid for quality PP recyclate to encourage more PP recycling.
PE-HD comes in five distinct classes, film-, pipe-, injection (crate)-, bottle- and chemical container grade. Recyclers often won’t recycle more than one or two PE-HD grades. For this report, all PE-HD was grouped together.
A total of 45 950 tons of PE-HD was recycled in 2012. PE-HD crates are a good example of closed-loop recycling in South Africa where at least 3 of the large crate producers have their own in-house recycling facilities for damaged and obsolete post-consumer crates.
The environmental drive by brand owners has developed into a strong demand for bottle- and film grade PE-HD. The small amount of available recycled film waste is supplemented with bottle grade, specifically white milk bottles, to meet the demand for carrier bags.
This resulted in a shortage of bottle grade and the recyclers have developed collection systems for chemical containers as a result. The recyclate can only be used for non-human contact applications and currently agricultural products like fencing droppers, poles and diamond mesh are made from recycled chemical containers sourced from farms. The logistics and residual content make this a challenging waste source.
The materials in Figure 10 not listed individually include the smaller families, i.e. PVC-U, PVC-P, PMMA, E/VAL, PA, PC, ABS and multi-layers.
Market applications for “Other” include injection moulded products, blow moulding applications like toys and multi-layer chemical containers, compression moulding and a small trader market.
Note: The market applications listed above are only for the 59 recyclers surveyed and not for the complete 210 recyclers’ markets.
Recyclers are still of the opinion that the largest growth in recycling would be in post-consumer recyclables. Smaller quantities of recyclables - 58.5% -were sourced from landfill and other post-consumer sources in 2012 versus the 70% in 2011. This could have been as a direct result of the increased electricity spending that impacted on wash plant recycling processes. The transport strike in June 2012 was also listed as a reason as mainly post-consumer recyclable waste is sourced from outlying areas. It specifically impacted on PE-LD. The material obtained from theSeparation at Source projects in the larger metropolitan areas is in high demand because of the lower contamination levels.
Toll and in-house materials are not generally included in the recycling figures. The 6.7% shown here is where the recyclers cannot differentiate between operating costs of toll tonnage and normal recycling.

If a recycling operation is compared with other plastics converting operations that are doing a similar tonnage per annum, the recycler has higher operating costs with regards:
Figure 12: Average operating cost in 2012 of recyclers that granulate, wash and pelletise
The actual operating costs of the 39 recyclers surveyed that granulate, wash and pelletisewere taken into account to calculate operating costs for 2012, as illustrated in Figure 12. When compared to 2011, total operating costs increased by 36.5%.Although the cost of electricity increased dramatically in the last 24 months, the portion of the overall operation costs stayed more or less the same. This is due to considerable measures taken by recyclers to contain the energy costs in their factories.
The calculated average cost of repairs and maintenance doubled since 2011. This could be due to the huge price increases of steel in the last 12 months.
Another change to note is the cost of financing which increased by 389%. The reason could be that it is still challenging to access incentives and grants for recycling and recyclers have been financing their investments through the usual financial institution channels. It could also be that not all financing costs were recorded in 2011 and as the trust in the survey process increased, the figures are more realistically reflected.
The historic buying and selling prices of the most popular grade of the three main plastics were recorded for May 2013 (when the data was collected). The average historical prices are recorded here.

The selling prices do not reflect the increase in operating costs. The calculated average margin only increased 2% versus the 36.5% increase in operating costs from 2011 to 2012. Recyclers are locked in with selling prices and will have to change their tactics and business models if they would like to continue operations in the near future. There are only three recyclers that have managed to keep selling prices aligned with operating costs and to keep track of virgin polymer prices. The bulk of the recyclers are trapped in a decreasing operating window.
The capital replacement value of plant and equipment is calculated at R5 384 per ton recycled in 2012 for recyclers that granulate, wash and pelletise. This is 11.5% more than the recorded figures of 2011 where the capital investment was R4 828 per ton recycled. (The 2011 published figure of R3 250 invested per ton recycled included recyclers that only granulate. The figure was subsequently amended to reflect recyclers who granulate, wash and pelletise.)
The recyclers interviewed invested 6.3% of their capital in 2012 vs. 12.1% in 2011. This investment can now be seen in the higher capital per tonnage. Recyclers are of the opinion that it is difficult to invest in operations if the supply of recyclable waste cannot be guaranteed.
Most recyclers are owner businesses and don’t do any direct business with state-owned companies. The need for a BEE rating is therefore not perceived as critical. Recyclers surveyed in 2013 predominantly don’t know their BEE status. This however, can be a stumbling block if government funding is to be accessed.
Although only 59 of the recyclers were contacted for detailed information, the author is familiar with the plastics recycling industry and has regular contact with the larger as well as the small recyclers.
Retail and brand owners are starting to see the importance of recycled content and are instructing their suppliers (the plastics product manufacturers) to source recyclate. The demand for cheap recyclate still exceeds the supply. Plastics recyclers will have to market themselves and their products totally differently to enable them to sell at market related prices. Recyclers are accustomed to customers contacting them for material at a specific price. They are not used to hard selling of neither their products nor its advantages.
The polyolefin recyclers are also looking towards the newly formed PolyCo to assist with telling the story in aggressive marketing campaigns. Despite all the efforts of the industry as a whole, the general public, brand owners and even players in the field, still don’t know the magnitude of the recycling industry in South Africa.
Alternative recycling methods, such as “energy from waste” and liquid fuels will have to be researched and developed into operational plants to grow the recycling rates to levels where zero waste to landfill at least looks like a possibility.
The plastics recycling industry is growing and new entrants are joining the industry on a monthly basis. It is, however, only the long-standing recyclers that have the tenacity and stamina to continue year in and year out with small increases in efficiencies that grow the recycling tonnages in small increments.
One standard concern for all recyclers is the availability of incoming recyclable waste. Truckloads of baled material arebought by agents that shipwaste outside the country. Waste pickers at ground level consider alternative income generating activities such as fruit picking and fishing – especially in the Western Cape. Larger collectors look for markets elsewhere.
In Europe, the plastics industry states that the maximum economic recycling rate for plastics is about 35%. South Africa has a few advantages, for example availability of cheaper sorters. We are also far ahead of Europe with the recycling of thin film. We are developing a stronger non-packaging recycling industry for the polyolefins. South Africa will probably be able to reach a 40% recycling rate with the following factors in place:
The plastics industry will have to work together with one voice if it is to convince government, retail and the public that we mean business with recycling and are professional and credible in what we recycle.
