The second priority, resource recovery, maximises options for re-use, recycling, reprocessing and energy recovery.
Where avoiding and reducing waste is not possible, the next most preferred option is to re-use the materials without further processing, avoiding the costs of energy and other resources required for recycling. For example, many household and industrial items can be repaired, re-used, sold or donated to charities.
Re-use (without further processing) and recycling (processing waste materials to make the same or different products) keeps materials in the productive economy and benefits the environment by decreasing the need for new materials and waste absorption.
Where further recycling is not feasible, it may be possible to recover the energy from the material and feed that back into the economy where this is acceptable to the community.
Some materials may be inappropriate to re-use, recycle or recover for energy and instead require treatment to stabilise them and minimise their environmental or health impacts.
