These advanced polymers are typically made from sustainable, renewable sources such as plant-based materials (starches, cellulose) and algae, making them more environmentally friendly.

Conventional plastics are made from fossil fuels and do not readily decompose, leading to their accumulation in the environment and the formation of harmful microplastics.

The capture process for CO2 can be energy-intensive and costly, and finding economically viable and safe storage solutions are ongoing challenges for CCUS.

Direct Air Capture (DAC) technologies are designed to extract CO2 directly from the atmosphere, regardless of the emission source, to help reduce existing greenhouse gas concentrations.

Utilization in CCUS involves finding practical applications for captured CO2, such as its use in manufacturing concrete, chemicals, or synthetic fuels, thereby creating economic value.

CCUS technologies primarily target CO2 emissions from large point sources like industrial facilities and power plants, as well as directly from the atmosphere (Direct Air Capture).

CCUS is an acronym for Carbon Capture, Utilization, and Storage, a set of technologies aimed at reducing CO2 emissions.

Water scarcity has profound implications for human well-being, including health and nutrition, and can hinder economic growth and potentially lead to conflicts.

The report emphasizes that the growing water crisis is a result of multiple factors, including inefficient water use, pollution, and the accelerating effects of climate change.

While population growth, unsustainable practices, and climate change contribute to water stress, increased efficiency in industrial water use would generally alleviate, not exacerbate, the problem.
