@ Perth, please have a look of attached file. Beside this, vermicomposting, use cloth bags, less paper usage, use of less packaging food material and to avoid bottle drinks may reduce and help to manage the wastes.
Anaerobic digestion for production of biogas (and thus electric and thermal energy) or biomethane after CO2 capture. And the digestate is further used to produce a slow-release fertilizer. Direct composting can also be carried out.
These are the main choices nowdays, otherwise hydrothermal liquefaction is another choice, but certainly more expensive.
