A team of researchers has developed **an innovative ecological method** to **extract gold from [disused electronic devices](https://noticiasambientales.com/residuos/tecnologia-en-desuso-ambiente-en-alerta-mendoza-la-dara-una-nueva-oportunidad-a-los-residuos-electronicos/)**. Through the use of **an inexpensive powder and saltwater**, this process promises to transform the recovery of precious metals, avoiding the toxic chemicals traditionally used.
Computers, cell phones, and other discarded devices **contain small amounts of gold that** were previously difficult to recover without harming the environment. The new system simplifies this process, making it easier to separate gold from other components efficiently and safely.
This advancement **stands out for its low cost and accessibility**, allowing communities with fewer resources to participate in the circular economy. Instead of ending up in electronic landfills, **used devices become a source of sustainable recovery**.
The recovered gold can **be reintroduced into the technological industry**, **reducing the need for mining extraction**. This technique opens a concrete path to reduce the environmental pressure generated by the accelerated consumption of electronic devices.
## A tool for electronic waste recycling
In addition to being effective, **the methodology is simple and applicable on a small scale**, allowing individuals, local businesses, and even educational centers to participate in metal recovery. This promotes **[greater environmental awareness](https://noticiasambientales.com/residuos/carlos-paz-reciclo-mas-de-42-toneladas-de-residuos-electronicos-y-avanza-hacia-una-gestion-ambiental-sostenible/)** and **encourages responsible recycling practices**.
In many regions, **electronic waste poses a growing challenge**. Initiatives like this offer a concrete response, where the hidden value in **waste becomes an opportunity to create green jobs** and **reduce the environmental footprint**.
The simplicity of the process also **drives decentralization of recycling**. With minimal training, anyone can contribute to the recovery of valuable resources, reducing waste and extending the lifespan of noble materials like gold.
## Perspectives for a circular economy
The development of this technique not only brings **environmental benefits** but also **economic and social benefits**. The possibility of recovering gold without polluting the environment helps to **revalue electronic scrap** and reduce dependence on intensive mining.
Moreover, this model **can be adapted in the future for the extraction of other metals** present in devices, such as silver, palladium, or copper. With each step, a vision of more sustainable production and consumption is strengthened.
This advancement **represents a concrete commitment to ecological innovation**, at a time when rethinking industrial processes is no longer an option but an urgent necessity. Technology, when properly directed, can be a key ally for a fairer and cleaner future.
