#区块链如何促进废物管理创新#
Waste management is an essential procedure as it entails the actions and activities, such as treatment, transportation, and collection, necessitated in the disposal and control of waste. Additionally, waste takes different forms ranging from gas to liquid matter.

As we continue adapting tech-savvy lifestyles, the issue of electronic waste or e-waste has become prevalent as the usefulness of many electronic gadgets and products continues to diminish. According to a United Nations report, the world emits as much as 50 million tonnes of e-waste worth $62.5 billion annually, and this exceeds the GDP of most nations. On the other hand, the amount of municipal solid waste produced yearly surpasses 2.01 billion tonnes.

These statistics, therefore, show how prudent it becomes to have efficient waste management measures. Blockchain can come in handy in the realization of this objective through the creation of a trustworthy, transparent, and immutable supply chain network for a plethora of different records. This technology can aid in the digital tracking of information, allowing an in-depth analysis of supply chains.

Trading off waste for digital tokens

When it comes to waste management, creativity, and tech-savviness are necessitated as they encourage people to incorporate more environmentally friendly measures. For instance, by offering some form of compensation, people will feel entitled to dispose of waste in the right manner.

Blockchain has proven to be an ideal player in initializing digital tokens. For instance, a Canadian company called Plastic Bank in operation in Haiti and Peru utilizes a blockchain solution to reduce the ecological ruin prompted by plastic waste.

The company has strategically located recycling centers where people take their waste, such as empty plastic water bottles, cups, and bags in exchange for digital tokens secured via a blockchain platform and can be redeemed for food or charging phones. All the plastic collected is then sold to a buyer for recycling purposes.

This blockchain model is gaining traction because an Italian town called Miglianico borrowed a leaf by implementing a similar idea. Through a blockchain-powered “Pay as You Throw” (PAYT) model, the town has been able to enhance waste management as the annual cost of waste collection has decreased from €900,000, approximately $974,000, to €600,000, nearly $649,000.

Miglianico uses both the blockchain-powered PAYT model and radio-frequency identification (RFID) tags pegged on sacks and bins. Collection staff is offered wristbands for scanning residents' waste. This approach has enabled the town to realize 85% of waste management efficiency.

Solving the e-waste puzzle

The present recycling management systems are, at times, characterized by cheating as owners usually exploit loopholes to make more profit. For instance, staff may be coerced to collect recyclable items but not make records on the same.

With blockchain, these loopholes will be sealed because a transaction will have to be stored on its distributed ledger technology (DLT) that guarantees tamper-proof records. For example, blockchain can be incorporated into satellite recycling machines where people can be enticed to exchange their functionless and old electronics and gadgets with digital tokens.

South Korea’s Jeju Island has heeded to this call because it revealed the implementation of a blockchain-enabled electric vehicle waste-battery distribution management network meant to curb depleted electric vehicle batteries last month.

Real-time tracking of waste

The other solution blockchain can offer in waste management is real-time tracking. Given that blockchain is a digital ledger network, transactions are stored both publicly and chronologically. As a result, this can boost the easier tracking of recycling and waste shipments, as well as propel regulatory compliance.

For instance, in September 2019, Waste2Wear, a Dutch green fabrics company, launched the first-ever fabric collection meant to convert ocean plastics into eco-fabrics.

Climate change and global warming are predicaments continuously wreaking havoc in modern society, and this is partly caused by inadequate waste management solutions. Blockchain, however, offers hope for boosting waste management measures through various strategies, such as distributed ledgers and digital tokens.

废物管理是必不可少的程序，因为它涉及废物处理和控制中必须采取的行动和活动，例如处理，运输和收集。另外，废物采取从气体到液体物质的不同形式。

随着我们继续适应精通技术的生活方式，随着许多电子产品和产品的实用性不断下降，电子废物或电子废物的问题已日益普遍。根据联合国的一份报告，世界每年排放 多达5000万吨的电子废物，价值625亿美元，这超过了大多数国家的GDP。另一方面，每年产生 的城市固体废物量超过20.1亿吨。

因此，这些统计数据表明采取有效的废物管理措施变得多么谨慎。通过为众多不同记录创建可信赖，透明且不可变的供应链网络，区块链可以在实现这一目标方面派上用场。这项技术可以帮助对信息进行数字跟踪，从而可以对供应链进行深入分析。

权衡浪费数字令牌

当涉及废物管理时，就必须鼓励创造力和技术意识，因为它们鼓励人们采取更加环保的措施。例如，通过提供某种形式的赔偿，人们将有权利以正确的方式处置废物。

事实证明，区块链是初始化数字令牌的理想参与者。例如，一家在海地和秘鲁运营的名为“塑料银行”的加拿大公司利用区块链解决方案来减少塑料垃圾引发的生态破坏。

该公司在战略上位于回收中心，人们可以将废物如空的塑料水瓶，杯子和袋子放在废物处理中心，以换取通过区块链平台保护的数字令牌，并可以兑换成食品或为电话充值。然后将收集到的所有塑料出售给买方以进行回收。
