2 - Recycling and Separation Processes 1

These flashcards cover key concepts related to recycling and separation processes, focusing on definitions and principles discussed in the lecture.

Material Recovery Facilities (MRFs)

Processing plants that separate comingled materials.

Separation Technologies

Methods used to separate mixed materials based on different characteristics.

Size Reduction

The process of breaking down materials to a smaller size to facilitate separation.

Efficiency Calculation

A method to assess the performance of a separation process, often expressed as a ratio of useful output to total input.

Rittinger’s Law

A principle stating that the energy required for size reduction is proportional to the change in surface area.

Kick’s Law

A principle suggesting that the energy required for size reduction is proportional to the increase in surface length.

Bond’s Law

An intermediate relationship proposing that the energy required for size reduction is proportional to the 3/2 power of the change in particle size.

Separation Process Flowsheet

A schematic representation that outlines the steps and equipment involved in recycling and separation processes.

Feedstock

Material input into a recycling or separation process.

Recovery Yield

The percentage of a specific material that is successfully extracted from the input stream in a separation process.
