Making a case for the consideration of trust,justice, and power in conservation relationships

In conservation, trust and justice are increasingly recognized as both intrinsically valuable and critical for successful socioecological outcomes. However, the interdependence between these concepts has not been explored. The conservation trust literature provides examples of efforts to build trust between conservationists and local actors; yet, these interventions are often conceived to incentivize local cooperation within dominant paradigms. We argue that when trust building is promoted as a technical fix that does not plan in advance to address power asymmetries in conservation practice, inequities may inadvertently be re-embedded. Therefore, we conceptualized a framework that joins trust, justice, and power so that critical analyses of conservation partnerships can be more effectively undertaken. We drew on environmental justice theory to better calibrate the trust literature for the historical-political settings of conservation, especially in the Global South. Justice and trust share strong theoretical links where perceptions of justice shape a willingness to trust, and, equally, trust is a precondition for justice to be perceived. Different forms of trust connect to varied domains of justice and power in different ways, which mediates the outcomes of interventions. We applied our framework to case studies to explore how these interdependences play out in practice. Failure of agencies to attend to issues of maldistribution, misrecognition of cultural values and knowledge, and exclusion from participation strongly compromised trust. Moreover, the ways in which nature-dependent communities and marginalized conservation workers are trusted, or the conditions under which they give trust, can lead to partnerships being perceived as just or unjust. Focusing on trust and justice can help identify power dynamics so they can be addressed more readily and create space for alternative understandings of partnerships.

Tannic acid as a novel and green leaching reagent for cobalt and lithium recycling from spent lithium-ion batteries

Tannic acid–acetic acid is proposed as novel and green chemicals for cobalt and lithium recycling from spent lithium-ion batteries through a leaching process. The synergism of both acids was documented through batch and continuous studies. Tannic acid promotes cobalt dissolution by reducing insoluble Co³⁺ into soluble Co²⁺, while acetic acid is critical to improve the dissolution and stabilize the metals in the pregnant leach solution. Based on batch studies, the optimum conditions for metal recovery at room temperature are acetic acid 1 M, tannic acid 20 g/L, pulp density 20 g/L, and stirring speed 250 rpm (94% cobalt and 99% lithium recovery). The kinetic study shows that increasing temperature to 80 °C improves cobalt and lithium recovery from 65 to 90% (cobalt) and from 80 to 99% (lithium) within 4 h at sub-optimum condition (tannic acid 10 g/L). Kinetic modeling suggests the leaching process was endothermic, and high activation energy indicates a surface chemical process. For other metals, the pattern of manganese and nickel recovery trend follows the cobalt recovery trend. Copper recovery was negatively affected by tannic acid. Iron recovery was limited due to the weak acidic condition of pregnant leach solution, which is beneficial to improve leaching selectivity.
