Stakeholders, Data and Sequestration

hm interesting

What is a Stakeholder?

An individual or organisation with interest in decisions being made affecting a natural or manmade system.

Traditional Values

Perspective of Aboriginal and Torres Strait Islander peoples, laying close with the natural world and sacred land.

Anthropocentrism

The environment as a source to humanity, human centred.

Ecocentrism

The ecosphere and its parts as central importance, nature centred.

Biocentrism

Earth and its organisms that are living disregarding their human usefulness. Living thing centred.

Technocentrism

Values technology, its ability to control and protect the environment. Technology centred.

Proxy Data

Paleoclimatologist

A scientist who studies climates of the past.

Carbon Capture and Storage

Carbon capture and storage is the process of capturing carbon that is being produced while fossil fuels are in use. It extracts the carbon that is already in the atmosphere, capturing it so it isn’t emitted into the atmosphere and stays there.

Process of Carbon Capture and Storage

\
Pre-combustion: applying the technology causing reactions with the carbon forming syngas. Reactions continue happening and eventually it is turned from carbon dioxide to hydrogen.

Post-production: separating the carbon dioxide from exhaust gases in a facility’s smoke stacks.

Geological Sequestration

Done deep underground in pockets of rock formed from the extraction of fossil fuels. The rock pocket is studied beforehand to make sure that the carbon cannot escape.

Biological Sequestration

Storing carbon in plants, large carbon sinks. This takes advantage of photosynthesis. Can also be done underground in seaweed farms.

Water Desalination and Process

Thermal: the use of heat to evaporate water, collecting the fresh water as condensation and then leaving behind the salts.

Membrane: Reverse osmosis. Water is pushed through a semipermeable membrane, where the pores are small enough for only the water to fit through, not the salts.

Water Reclamation

Converting wastewater into water that can be used again. Recycled water comes from greywater and stormwater. Wastewater is treated at a water treatment plant that must follow strict guidelines in order to produce safe and clean water.
