The search for sustainability has now become a duty for all those entities, nations or people who intend to combat poverty in the world, safeguard the environment and bridge the gap of disparities that unfortunately still exist between underdeveloped countries and medium-high developed nations.

The agrifood sector plays an important role in this vision, and the development of sustainable analytical devices at low cost and easy to use for everyone, suitable for being adopted by those countries whose technological development does not allow them to take up expensive and sophisticated laboratory techniques, may constitute a contribution towards achieving the objectives listed above.

In this review we illustrate some examples of electrochemical devices realized utilizing sustainable materials, such as paper, as support for disposable and reagent-free (bio)sensors applied to the monitoring of food quality and safety. We also mention the first applications of new carbonaceous materials obtained from the recycling of agrifood waste products, which promise interesting features for electrochemical applications.

现在，寻求可持续性已成为所有打算与世界上的贫困作斗争，保护环境并弥合差距的桥梁，这些不幸的是，欠发达国家和中高发达国家之间仍然存在这种差距。

农业食品部门在这一愿景中起着重要作用，其低成本和易于所有人使用的可持续分析设备的开发非常适合那些技术发展使其无法采用昂贵且复杂的实验室技术的国家采用，可能有助于实现上述目标。

在这篇综述中，我们举例说明了利用可持续性材料（例如纸）实现的电化学设备的一些示例，以支持用于食品质量和安全监控的一次性和无试剂（生物）传感器。我们还提到了从农业食品废品的回收中获得的新型碳质材料的首次应用，这些材料有望为电化学应用带来有趣的功能。
