It\u2019s a mystery researchers at the <a href=\"http:\/\/www.ceas.manchester.ac.uk\/\">School of Chemical Engineering and Analytical Science (CEAS)<\/a> set out to uncover.<\/p>\n<p>The resulting paper, published in <em>Science of the Total Environment<\/em>, reveals that the EU is home to between 117 and 200 million working kettles. That\u2019s a lot of brews.<\/p>\n<p>The team compared the environmental impact of plastic, metal and eco kettles from manufacture through to end of life. The main finding was that the eco-kettle has a 30% lower environmental impact than plastic and metal kettles thanks to better power efficiency. With 80% of a kettle\u2019s environmental impact occurring during its usage stage, this is the area where the most work needs to be done to reduce its carbon footprint.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-825\" src=\"https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Kettle-3-1024x683.jpg\" alt=\"\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Kettle-3-1024x683.jpg 1024w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Kettle-3-300x200.jpg 300w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Kettle-3-768x512.jpg 768w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Kettle-3.jpg 1555w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<h2>One cup or two?<\/h2>\n<p>So, whose irresponsible tea-making behaviour is damaging the planet? Well, if you ever fill your kettle to the top \u2013 and, let\u2019s face it, many of us do \u2013 then hang your head in shame.<\/p>\n<p>Boiling only the water you actually need for the drinks you\u2019re preparing can reduce the environmental impact of kettles by around a third. Over the lifetime of a kettle, and across the millions of kettles in use throughout the EU, this could add up to a huge saving.<\/p>\n<p>Having said all that, the researchers acknowledge that many people prefer the convenience of filling their kettle up at the start of the day so they don\u2019t have to do it again. They recommend encouraging people to change this habit.<\/p>\n<p>Another tip is to only boil the water to the temperature you need for the drink you\u2019ve chosen. For example, green tea shouldn\u2019t be brewed in boiling water. This simple change could also add up to an environmental saving \u2013 and a better drink.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-827\" src=\"https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Microwave.jpg\" alt=\"\" width=\"772\" height=\"513\" srcset=\"https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Microwave.jpg 772w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Microwave-300x199.jpg 300w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Microwave-768x510.jpg 768w\" sizes=\"auto, (max-width: 772px) 100vw, 772px\" \/><\/p>\n<h2>Inconvenience food<\/h2>\n<p>If all this is making you feel a little guilty, we\u2019re not finished yet. Your kettle is not the only thing in your kitchen that\u2019s hurting the planet every time you use it. Please step forward, the microwave.<\/p>\n<p>In a separate piece of research from CEAS, scientists conducted the first ever full review of the impact a microwave has on the environment from its manufacture right the way through to its disposal. And while it may have your meals ready in a flash, its impact on the health of our planet is far from convenient &#8211; in fact, it could be as bad for the environment as cars.<\/p>\n<p>While their manufacture and disposal certainly harm the environment, it is the electricity these machines consume as they blast your ready meal that has the greatest negative impact. Across the EU, 9.4 terawatt hours of electricity are used by microwaves every single year. On average, a single microwave uses 537,000 watts of electricity over its eight-year life &#8211; equivalent to the power it takes to light nearly nine thousand 60W light bulbs for one hour.<\/p>\n<p>CEAS&#8217; Dr Alejandro Gallego Schmid says: \u201cGiven that microwaves account for the largest percentage of sales of all type of ovens in the EU, it is increasingly important to start addressing their impact on resource use and end-of-life waste.\u201d<\/p>\n<p>Two decades ago when microwaves became regular features in the kitchen, the device would last between 10 and 15 years. Today, owners typically throw out their microwaves when they\u2019re between six and eight years old. This only adds to their harmful impact on the environment.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-828\" src=\"https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Sandwich-1024x678.jpg\" alt=\"\" width=\"1024\" height=\"678\" srcset=\"https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Sandwich-1024x678.jpg 1024w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Sandwich-300x199.jpg 300w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Sandwich-768x509.jpg 768w, https:\/\/www.mub.eps.manchester.ac.uk\/science-engineering\/wp-content\/uploads\/sites\/59\/2018\/01\/Sandwich.jpg 1478w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<h2>Please don\u2019t ruin sandwiches for us too!<\/h2>\n<p>Sorry, but even the humble sandwich \u2013 something that distils the very essence of Britishness down to snack form \u2013 is responsible for its share of environmental damage.<\/p>\n<p>Determined to rip the heart out of the heart of our home, those CEAS researchers have also uncovered the environmental cost of enjoying a sandwich &#8211; both homemade and shop-bought. While you may think about your own health when choosing your sandwich, you should start thinking about the Earth\u2019s too \u2013 as it turns out those delicious all-day breakfast sandwiches are bad for us both.<\/p>\n<p>More than 11.5 billion sandwiches are consumed each year in the UK. And in case you\u2019re interested, chicken salad, BLT, Ploughman\u2019s and egg and cress are among the nation\u2019s favourite readymade sarnies, while ham and cheese reigns when we\u2019re preparing our own.<\/p>\n<p>The researchers looked at 40 different sandwich recipes and concluded that the carbon footprint of the snacks could be reduced by as much as 50 per cent if a combination of changes were made to the recipes, packaging and disposal.<\/p>\n<p>Homemade sandwiches have a smaller environmental impact, mainly because the production of commercial sandwiches requires a fifth more ingredients due to food loss during the manufacturing stage. They also have to be kept refrigerated until the point of sale, whereas a sarnie you make at home can be eaten straight away.<\/p>\n<p>So how can we make our favourite snack greener? Among the recommendations, the researchers suggest extending sell-by dates, which are currently on the overly cautious side, and reducing or removing certain ingredients that have a large carbon footprint, like lettuce, tomato, mayonnaise and pork products. Interestingly, the carbon footprint of a breakfast sandwich is double that of an egg and cress \u2013 although no correlation between nutritional value and carbon footprint was found.<\/p>\n<p>The conclusion is that making a sandwich yourself rather than buying one readymade is not only better for your wallet, it\u2019s also better for the planet. While there is still an environmental impact, such as the manufacturing, packaging and refrigeration of the ingredients you choose, it is far less than that of a pre-packaged sarnie. Plus, you have the option of using leftovers and keeping waste to a minimum.<\/p>\n<p>And remember, however guilty you\u2019re feeling about buying that sandwich, at least you\u2019re not microwaving it (unless you\u2019ve treated yourself to a microwavable sandwich, in which case you may as well fill up your kettle to the top too while you\u2019re at it.)<\/p>\n<p>We hope we haven\u2019t ruined your lunch for you.<\/p>\n<p>&nbsp;<\/p>\n<p><em>Words &#8211; Hayley Cox<\/em><\/p>\n<p><em>Images &#8211; <a href=\"https:\/\/www.flickr.com\/photos\/joeri_van_veen\/5439425621\/\">Joeri van Veen<\/a><\/em><\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/catman103\/4248412717\/in\/photolist-7tqe68-5QRifg-2vo9F-dzzhqe-moh9jW-6CeLgi-p6AoHN-K4rqa-4hGEju-dKcsU-5k1AwB-dYcBP-2n5iFD-azLMCz-5N51b8-9uiLAV-anbdVj-eY7rB3-coc25q-brFAm-2eBSzo-59v7Qd-qSCpdr-9uiLJ8-3jM5Lk-TUDYpz-s3Qam-GaeYKT-TzJiCQ-9eJmaV-UZLyxa-WzfqGJ-y4vxf1-ozpwXK-k89q3-b3ghmz-cjXqiq-bwcxX4-hcvJv-4nvjuJ-8R1Ddk-8AN3SK-DoTkRR-7H13iB-jpkumx-Hdfx2U-aeZrVs-Nca49-8EnPKo-eeGfek\"><em>Catman103<\/em><\/a><\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/39877441@N05\/17118540890\/in\/photolist-s5GZNJ-37zdDK-LcAV1-dqH5nG-76L4RS-9qjAya-fJ6Nbg-Hb5pUm-5QsFtU-5QsF5N-hV4dSs-9LSPce-4SEzZQ-j3yWP3-f3ZW9E-bMt7ZB-bH3nGD-8fgAb1-5zpqva-9Ddr2j-bu8yJs-54gjBW-6pTARk-syGiw-5SpzgV-qCLQv-4sSad5-4gMr29-TJtp71-54gjR1-vzL8iF-6pTB1B-buPREY-9wwdFH-HSihs-5qmGmq-8ssaX-5qhqtk-6AYc8h-6T9uA2-4DsucD-TJtpXE-fuYDJ1-7at3j4-5qmQhd-etC86Q-dPPdqR-5MagPX-5qmQVo-P7JTK\"><em>Michael Levine-Clark<\/em><\/a><\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/lord_edricus\/3102937045\/\"><em>Jonas Evertsson<\/em><\/a><\/p>\n<p><a href=\"https:\/\/www.flickr.com\/photos\/gabrielgm\/10695745316\/\"><em>Gabriel Garcia Marengo<\/em><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This Dry January, you\u2019re probably putting your kettle through its paces \u2013 replacing beer with healthy green teas and energising coffees.
