In the UK, potato crisps producer Walkers, a PepsiCo<\/a> brand, has partnered with rolled out technology that will use CO2 captured from beer fermentation in a brewery, mixed with potato waste, to produce fertiliser. The fertiliser will then used on fields for the next potato crop.<\/p>\n\n\n\n The process is expected to slash CO2 emissions from Walker’s manufacturing process by 70%.<\/p>\n\n\n\n Creating fertiliser normally produces high CO2 emissions, but the technology adopted by Walkers makes fertiliser without generating CO2.<\/p>\n\n\n\n The company has installed an anaerobic digester, which feeds potato waste to bacteria to produce methane. The methane is then burned to make electricity for the potato-frying process, thus reducing energy consumption.<\/p>\n\n\n\n The new system will go a step further by taking away potato \u201ccake\u201d left after digestion – and mixing with CO2 from local breweries to make an enriched fertiliser, which will help put carbon back into the soil as well as encourage plant growth.<\/p>\n\n\n\n The initiative is the result of a partnership with British clean-tech firm CCm Technologies<\/a>.<\/p>\n\n\n\n
