At least 2x buckets with lids that seal airtight are required. You can use food grade plastic buckets (or paint buckets) between 10 litres - 30 litres; or invest in purpose-built bokashi bins. Having more than one bucket means once your first bucket is full, another bucket can be started straight away.
Home compostable bin liner OR wood chip mulch.
Line your bucket with a home compostable bin liner to collect liquid from the pickling process; OR layer the bottom of your bucket with wood chip mulch to absorb this liquid.
Food scrap kitchen caddy.
Scraping food scraps into a small container or bucket (kitchen caddy) means you don't have to open your bokashi or 'pickling' system more than once a day. This could simply be a tupperware or ice cream container that sits on your kitchen bench or under the sink.
Potato masher or kitchen caddy lid.
Not absolutely necessary to have a separate potato masher but you do need something with a flat surface to squash and remove air pockets from your day's haul of scraps i.e. the lid of your kitchen caddy (if small enough) could be used.
Pickled Composting Flakes.
Absolutely necessary to have (lol)! Sprinkle 1-2 tablespoons of flakes evenly on your scraps to kick start or ramp up the pickling process. Make sure to double this amount if adding high protein rich foods (i.e. meat/fish/dairy) that break down more slowly.
Outdoor compost bin.
Once your food scraps have finished pickling you need to empty these into an outdoor compost bin (or bury in the garden) to break down completely. If there is no room for an outdoor compost bin where you live, join ShareWaste to locate a ShareWaste host to drop-off your food scraps for free.
