Abstract

The Paris Agreement on climate change (2015) emphasizes among other priorities the importance of environmental innovation, including technical, technological, organizational, which has significant potential to minimize the negative impact of the industry on the environment. In addition, customers, consumers and shareholders increasingly care and demand the same from our activities, our products and the services they consume. They expect companies to comply with environmental standards and demonstrate our commitment to reduce environmental impacts in daily operations. The task of technology modernization and relevant organizations for various sectors of the national economy. Especially important for energy companies (PERTAMINA). The author analyzes new environmental management tools, which were introduced in the ISO 140001: 2015 standard and outlines some recommendations for improvement in the context of PERTAMINA’s conditions. The author also analyzes how to align these requirements with the upcoming transition of energy companies to the best available technology, which is basically a form of increasing technical and technological innovation. To ensure the successful implementation of these innovations, it is necessary to use, in addition to environmental management standards, a mix of environmental policy instruments, including what is referred to as green finance. It may be a challenge, but it is also an opportunity for us to show our environmental responsibility, stand out from the competition and show our existing customers and potential evidence of our commitment.

Abstract

Recovery of valuable metals from spent lithium iron phosphate (LiFePO4) batteries are quite challenging because it needs a lot of process. The recycling of these spent batteries can avoid environment contamination from the waste, meanwhile the valuable metallic components in the batteries including lithium can be treated as a resource for potential recovery of lithium. Low concentration of sulfuric acid (H2SO4) as a leachant and hydrogen peroxide (H2O2) as an oxidant, was used to leach elements from cathode materials of spent LiFePO4 batteries that mainly contained Li, Fe and P. Li could be selectively leached into the solution and while Fe and P was assumed to remain in the residue. The significant effects of acid concentration, solid-liquid ratio, reaction temperature and reaction time on the leaching rate are determined. Under the optimum conditions of 0.1 M H2SO4, 2 vol% H2O2, S/L ratio of 75g/L, 60 °C and 60 min, the leaching efficiency determined were 74.74% for Li and 0.99% for Fe. A leaching mechanism of shrinking-core model with diffusion through product layer control was proposed. It was found that the apparent activation energy was 12.69 kJ mol-1 as calculated by the Arrhenius equation together with an enthalpy (∆H) of 10 kJ mol-1 and an entropy (∆S) of -264.54 Jmol-1K-1.
