calcite plastic separation

Waste separation

Waste separation is one of the steps towards a circular economy. The better the quality of our waste, the higher the environmental benefit. According to a calculation by CE Delft, the CO2-profit from recycling plastic is 1.2 kg CO2-equivalent per kg recycled plastic. 37,000 kg of plastic waste was collected from the UM in 2021.

Frontiers

Reliable, easy, cost-effective and reproducible ways of extracting microplastics (MP) from environmental samples remain important requirements for MP research. In this context, electrostatic separation is a new proposition, especially for extracting MP from mineral-rich samples and large sample volumes. However, there is little research evaluating the reliability of the technique.

Photoelasticity

Photoelasticity describes changes in the optical properties of a material under mechanical deformation. It is a property of all dielectric media and is often used to experimentally determine the stress distribution in a material, where it gives a picture of stress distributions around discontinuities in materials. Photoelastic experiments (also informally referred to as photoelasticity) are an

What Is the Difference Between LimestoneCalcite?

Calcite is a mineral that occurs in the natural geological processes of the Earth. Calcite is a form of calcium carbonate, a type of calcium salt oxide with three atoms of oxygen bonded to one atom of calcium. Calcite binds with other compounds to create limestone which is used in construction.
