Our waste footprint
When we measure the waste impact of our products, we include the recycling of our packaging and the amount of leftover product in our packaging. This enables us to set ambitious targets, transparently report our performance and assess our progress.
Why do we measure our waste footprint?
We measure our waste footprint to track our progress towards our target to halve the waste associated with the disposal of our products by 2020. We use over 2 million tonnes of packaging each year, ranging from paper, board and metals (such as aluminium, steel and glass) to the plastics and mixed material laminates that we use in our sachets and pouches.
How do we calculate our waste footprint?
We measure our waste impact by quantifying packaging material that has not been reused, recycled or recovered, and the amount of product left over in primary packaging (for example, a mayonnaise bottle) after consumer use. This helps us to develop packaging material that is light yet sufficiently solid to protect the quality of our products. It also helps us design our packs so that as little product is left behind as possible when our consumers dispose of the packaging after use.
We’re also looking at packaging waste in the context of the local recycling infrastructure. If systems are in place to recycle packaging – and capture the value contained in the packaging that’s been thrown away – this reduces the overall environmental impact of the packaging waste.
We aim to choose packaging materials that are recycled or recovered in the countries where we sell our products through our target to ensure that all our plastic packaging is reusable, recyclable, or compostable by 2025. In addition, we are working to catalyse recycling rates through aiming to include at least 25% recycled plastic content in our packaging by 2025.
We have been calculating our waste footprint since 2010, using data from a representative group of products in all our 12 sub-categories: Beverages, Deodorants, Dressings, Fabric Sensations, Fabric Solutions, Hair Care, Home & Hygiene, Ice Cream, Oral Care, Savoury, Skin Care, and Skin Cleansing. Our footprint calculation focuses on 14 key countries (Brazil, China, France, Germany, India, Indonesia, Italy, Mexico, Netherlands, Russia, South Africa, Turkey, UK, and the US), which represent around 60-70% of our sales volume. Within the 14 key countries, the footprint accounts for at least 80% of Unilever’s sales volumes.
We calculate our waste impact annually, both at a total level and ‘per consumer use’, for example the waste impact of someone eating one serving of soup. These measurements enable us to see where we are making improvements and where we still have work to do, such as by further light-weighting our packs and using more recyclable materials.
Our 2019 waste footprint
Our absolute waste footprint is around 742 kilotonnes, which is equivalent to 0.6 g waste per consumer use. In 2019, we reduced our waste impact per consumer use by 32% compared to 2010.* This reduction was achieved through a combination of: disposing of brands with packaging that was not widely recycled in the country of sale; improvements in the recycling and recovery of packaging materials; and packaging innovations which have reduced the weight of materials used.
Our analysis shows that primary packaging accounts for 60% of our total waste footprint. Products within our Fabric Solutions, Fabric Sensations, Hair Care and Beverage categories make the largest contribution to our waste footprint, accounting for more than 40% of our total waste footprint.
Our footprint graphic below shows the contribution of primary and secondary packaging – minus national recycling and recovery rates (specific to each of the 14 countries where we measure our footprint) – to our total waste footprint. We also account for product leftovers – the product left behind in the primary pack when a consumer discards it. Together, these make up the waste footprint related to the disposal of our products.
