荷兰可持续牛仔倡议使用区块链来追溯棉花的可追溯性

2021-3-6 19:45

 

Denim Deal initiative与荷兰清洁技术公司The Movement合作,开发其区块链可追溯性解决方案Aware。


牛仔布行业面临着一些严重的环境挑战。据估计,生产一条牛仔裤需要使用8000升水,而全世界只有63%的水最终被销售出去。此外,只有0.1%的废弃材料在高质量的应用中得到重用。


牛仔协议试图通过促进牛仔行业的循环经济来解决这个问题。我们的目标是让来自整个价值链的成员致力于将回收纺织品用于所有牛仔产品作为荷兰市场的新标准。牛仔协会成员包括政府部门、回收公司和知名品牌。他们共同设定的目标是,在牛仔布交易网络生产的每一条牛仔裤中至少加入5%的回收材料。


Aware的纳米颗粒技术在证明最终的牛仔裤产品是由可回收材料制成方面发挥了作用。更具体地说,Aware可以追溯生产中使用的棉花的来源。它声称是世界上第一项追踪再生棉花的技术。


棉花种植是生产中用水量最大的农产品之一。由于棉花需求在短期内似乎不会放缓,找到回收现有材料的解决方案对于使纺织和时尚行业更具可持续性至关重要。据估计,即使只有20%的牛仔裤是由再生棉布制成的,整个过程将为每条牛仔裤节省750升水。


该运动的意识解决方案包括四个步骤。首先,制造商通过将纤维与特殊的微量示踪颗粒混合,激活回收棉花中的Aware示踪剂。这些粒子相当于一个安全的数字护照,其中包含特定回收材料的所有数据,护照上的信息存储在区块链上。然后纱线被用来生产任何产品。一种独特的扫描设备用于扫描最终产品中的微量颗粒,并确保它是由活化再生棉制成的。最后,如果产品上的指纹与数字护照上相应的信息相匹配,则该产品将被识别标签。该溶液也可用于聚酯。


仍然需要进行大量的审计,以确保与微观颗粒相对应的信息是准确的。尽管如此,该解决方案仍有潜力对绿色洗涤趋势做出重大改变,并促进消费者寻找可持续产品。


与此同时,Aware区块链由荷兰区块链初创公司Circularise提供能源,后者以追踪塑料从最初的树脂到最终产品而闻名。该公司通过欧盟的“地平线2020”计划获得了180万美元的资金,并与保时捷、日本丸宝集团、德国塑料公司DOMO和Covestro有合作项目。

 

The Denim Deal initiative partnered with Dutch cleantech company The Movement for its blockchain traceability solution Aware

The Denim industry faces some serious environmental challenges. It is estimated that 8,000 liters of water are used to produce a pair of jeans and that only 63% of production worldwide ends up being sold. In addition, only .1% of discarded material is reused in high quality applications. 

The Denim Deal is attempting to address the issue by promoting a circular economy in the denim industry. The aim is to get members from all across the value chain to work towards the use of recycled textile in all denim products as a new standard in the Dutch market. Denim Deal members include government departments, recycling firms and well known brands. Together they set the goal of incorporating at least 5% of recycled material into every pair of jeans produced within the Denim Deal’s network. 

Aware’s nanoparticle technology comes into play in proving that the final jeans products are made out of recycled material. More specifically, Aware is able to trace the origins of the cotton used in production. It claims to be the first technology in the world to trace recycled cotton.

The cultivation of cotton is one of the agricultural commodities that uses the largest amount of water in production. As demand for cotton does not seem to be slowing down any time soon, finding solutions to recycle existing material is essential to make the textile and fashion industry more sustainable. It is estimated that even if only 20% of jeans are made out of recycled cotton, the whole process will save up 750 liters of water per pair of jeans. 

The Movement’s Aware solution involves four steps. First, manufacturers activate Aware’s tracer in the recycled cotton by mixing the fiber with special microscopic tracer particles. The particles correspond to a secure digital passport that contains all the data on the specific recycled material, and the information on the passport is stored on blockchain. The yarn is then used to produce any product. A unique scanning device is used to scan the trace particles in the final product and ensure it is made from the activated recycled cotton. Finally, if the fingerprint on the products matches the corresponding information on the digital passport, the product is authenticated with an Aware label. The solution can also be applied to Polyester. 

Extensive auditing will still be necessary to ensure that the information corresponding to the microscopic particles is accurate. Still, the solution has the potential to make significant changes to green washing trends and facilitate consumers’ search for sustainable products. 

Meanwhile, the Aware Blockchain is powered by Circularise, a Dutch blockchain startup that is known for tracking plastics from initial resin to end product. The company received $1.8 million in funding through the EU’s Horizon 2020 program and has projects with Porsche, Japanese conglomerate Marubeni, and German plastic companies DOMO and Covestro.
