Responsible Materials Stewardship: Rethinking Waste Management Globally in Consideration of Social and Ecological Externalities and Increasing Waste Generation

Received: 04 September 2023;  Published: 04 January 2024;  doi: 10.21926/aeer.2401002

Abstract

Unsustainable material extraction, use and disposal - the ‘take-make-waste’ model - places communities globally in a state of social inequalities and environmental conflict (the slow violence of polluting the air, water, and soil we all depend). Current waste management practices are designed for efficiency of disposal but do not address increasing waste generation and waste externalities. The present global waste situation is magnified by exponential increases in plastic production; misconceptions of recycling; an [...]

The Arsenic Biogeochemical Cycle: A Review

Received: 02 September 2023;  Published: 23 November 2023;  doi: 10.21926/aeer.2304051

Abstract

This paper reviews the arsenic in the environment. Arsenic contamination is currently one of the leading environmental problems worldwide. The arsenic (As) cycle is the subject of this article because As is an element with a significant impact on living beings and because of its interrelation with other biogeochemical cycles. The biogeochemical cycle of As is closed, so this trace element returns to sediments where it can be changed in its chemical state by micro-organisms present in soils. In addition, some minera [...]
