BOTTLE MAKING 38 PET planet insider Vol. 15 No. 06+07/14 www.petpla.net Sidel’s approach to sustainability Value creation along the supply chain PET is already the world’s most widely recycled plastic and can further strengthen its position by taking what is currently in the waste stream and putting it in the resource stream as rPET whether for football kits or new bottles and reaching for the ultimate objective: a closed-loop packaging supply chain. However, opportunities remain to improve sustainability before packaging gets anywhere near the end user. Forecasts for 2030 suggest that demand for energy and food will have increased by 50%, and for water by 30%. Production of packaging and related products has to optimise resources by reusing and recycling wherever possible. Considerations about ‘Sustainable packaging’ minimi- sation of the environmental footprint through reducing use of raw materi- als and energy; employing renew- able energy during production and transportation; building-in recycling principles at design stage; incorporat- ing recycled content in the packaging; and sustainable end-of-life options. Optimising energy The blow-moulder accounts for as much as 70% of electricity con- sumption on a PET production line, a proportion being attributable to com- pressed air. Programs are available that measure electricity consumption and other factors such as air pressure and leaks, with mechanical testing on sub-assemblies. The process and technical qualities of the package and the production environment can be measured to provide a comprehensive analysis, enabling development of an action plan covering energy and cost- saving targets, with ongoing monitoring of consumption. Lamps can consume as much as 90-95% of the electrical power used by a PET blower; Eco ovens require fewer heating modules, can reduce preform heating time and boost energy efficiency. Eco lamps can offer sig- nificant savings: Sidel helped PepsiCo Deutschland to achieve savings of 19%, with a 12-month return on investment. Water and chemical usage Sidel’s Predis preform and Capdis cap decontamination systems use hydro- gen peroxide mist, with no water and very little chemicals. Traditional aseptic filling systems that require wet bottle rinsing consume approximately 180m 3 of water and 220l of chemicals/day. Lightweighting Sidel’s RightWeight bottle weighs 7.95g.
