Sustainable consumption and production

Sustainable consumption and production (SCP) is at the core of the United Nations Sustainable Development Goals (SDGs), specifically addressed by SDG 12. This goal aims to "ensure sustainable consumption and production patterns," acting as a cross-cutting theme that feeds into other SDGs such as those related to climate change, poverty, health, and sustainable cities.

SCP involves using services and products in a way that minimizes environmental damage, preserves natural resources, and promotes social equity. The purpose is to decouple economic growth from environmental degradation, which means pursuing economic development in a way that can be sustained by the planet over the long term. SCP requires changes at all levels of society, from individuals to businesses to governments.

At the individual level, SCP implies making lifestyle choices that reduce environmental impact. This might include reducing, reusing, and recycling waste, choosing products with less packaging, and opting for more sustainable forms of transport like cycling or public transport.

For businesses, SCP entails adopting sustainable business models and practices. This could include improving resource efficiency, investing in renewable energy, designing products that are durable and recyclable, and ensuring fair labor practices.

At the government level, SCP involves implementing policies that support sustainable business practices and incentivize sustainable consumer behavior. This might involve regulations to reduce pollution, subsidies for renewable energy, and campaigns to raise awareness about sustainable consumption.

SCP also plays a role in several other SDGs. For example, sustainable production practices can help mitigate climate change (SDG 13) by reducing greenhouse gas emissions. Additionally, by reducing the pressure on natural resources, SCP supports the goals related to life below water (SDG 14) and life on land (SDG 15).

While progress has been made in certain areas, challenges remain in achieving the shift towards SCP. These include existing patterns of overconsumption, limited awareness about the impacts of consumption, and the need for technological innovation to enable more sustainable production.

An ability to separate battery electrode materials while preserving functional integrity is essential to close the loop of material use in lithium-ion batteries. However, a low-energy and low-cost separation system that selectively recovers electrode materials has not yet been established. In this study, froth flotation experiments were carried out with a variety of new and spent lithium-ion batteries using kerosene as the collector. The products were characterized using thermogravimetric and chemical analysis.
Waste Li foils in the spent experimental Li-coin-cells may bring the potential risk and the waste of Li-resource if they aren't reasonably treated in time. For this purpose, waste Li foils were recycled in the form of black LiFePO4/C powders with the recovery of about 80% in this work.

There is a need to develop technology to enable a resource-efficient and economically feasible recycling system for lithium-ion batteries and thus assure the future supply of the component materials. Lithium-ion batteries are complex products, and designs and materials are still evolving, which makes planning for future recovery more challenging. Several processes for recycling are proposed or operating, and each has advantages and disadvantages. This paper compares these processes on technical and economic bases, elucidating differences in benefits as a function of cathode composition.

This paper contributes to the understanding of metal demand development over time by illustrating the impacts of different aspects of technological change using historical data. We provide a direct, quantitative comparison of relative change in global primary production for 30 metals over 21 years (1993–2013), capturing the range and variation of demand development for different metals within this period. The aspects of technological change contributing to this variation are investigated in more depth for nine metals.

Sensing volatile organic compounds (VOC) is a promising approach in particular for the development of non-invasive, fast and inexpensive tool for the anticipated diagnostic of diseases and monitoring of exposition to toxic molecules. This paper examines for the first time the potential of biobased carbon nanorods (CNR), synthesized by a simple and green method in gram scale via the pyrolysis of castor oil, to build the conducting architecture of quantum resistive vapour sensors (vQRS).
As an extension of a previous work (Chen and Han, 2015a), this study explored the arable land use of the world economy from source of exploitation to sink of final consumption via the global supply chain, by means of embodiment accounting that includes the indirect feedbacks associated with both intermediate and primary inputs. In magnitude, the global transfer of arable land use is estimated to be around 40% of the total direct exploitation. The connections as well as imbalances of major economies in intermediate and final trades of arable land use are discussed.
Food waste is a matter intrinsically linked with the growing challenges of food security, resource and environmental sustainability, and climate change. In developed economies, the largest food waste stream occurs in the consumption stage at the end of the food chain. Current approaches for dealing with the wasted food have serious limitations. Historically, livestock animals had functioned as bio-processors, turning human-inedible or -undesirable food materials into meat, eggs, and milk.
Evaluations of food, energy and water (FEW) linkages are rapidly emerging in contemporary nexus studies. This paper demonstrates, from a food consumption perspective, the potential of life cycle thinking in understanding the complex and often “hidden” linkages between FEW systems. Our study evaluates the upstream virtual water and embodied energy in food consumption in the Tamar catchment, South West England, distinguishing between domestic production and imports origin.

Sustainable use and management of nutrients is an important issue for food, energy and water systems. The close connections between the three systems, reflected by the “nexus” concept, warrant an integrated approach to nutrients management across the nexus. In this paper, dynamic modelling of nutrient flows in a local food-energy-water system is presented and applied to a simplified case study.
