more efficient, taking up 21 percent less space and weighing two-thirds of a tin can of equivalent volume. Recycling Since aseptic packages contain different layers of plastic and aluminium in addition to raw paper, they cannot be recycled as "normal" paper waste, but need to go to special recycling units for separation of the different materials. As a result, Tetra Pak cannot be put in recycling or compost bins. Recycled Tetra Pak's may be used in producing polythene based products and construction material, third largest contributor to carbon footprint. Tetra Pak has operated limited recycling since the mid-1980s, introducing a recycling program for its containers in Canada as early as 1990. In 2000, Tetra Pak invested 20 million baht (€500,000) in the first recycling plant for aseptic packages in Thailand. Recycling aseptic packages has been one of Tetra Pak's challenges. Once separated, the aseptic carton yields aluminum and pure paraffin, which can be used in industry. Even without separating the carton materials, however, the aseptic carton can be reused, for example, in engineering equipment. In 2010, 30 billion used Tetra Pak cartons were recycled, a doubling since 2002. The company aims to double the recycling rate within the next ten years, something that will require the engagement of the entire recycling chain. As of 2011, 20 percent of Tetra Pak cartons are recycled globally, with countries like Belgium, Germany, Spain, and Norway showing local recycling rates of over 50 percent. To increase the level of recycling and meet its targets, Tetra Pak engaged in driving recycling activities such as developing collection schemes, launching new recycling technologies, and raising awareness of recycling and sustainability. Used Tetra Pak packages have been recycled as construction material in design projects, with varying results. By 2017, 25% of Tetra Pak cartons were recycled globally. At that time, the company announced that global recycling rates would no longer be one of its main metrics measured in sustainability reports, abandoning its previous target of increasing recycling rates to 40% by 2020, and instead introduced new metrics to measure against, such as public outreach, access to recycling facilities, and recycling capacity. In 2018, Tetra Pak signed an agreement with the environmental services company Veolia "to recycle all the components of used beverage cartons collected within the EU by 2025." Tetra Pak has also partnered with the Certified Renovated Equipment organization to refurbish old equipment so it can be
