A HUGEAMOUNT OF FOODWASTE ENDS UP IN LAND­FILLS EV­ERYYEAR, BUT IT DOESN’T HAVE TO. FOODWASTE DIS­POSERS MAKE DEAL­ING WITH HOUSE­HOLD FOODWASTE SIM­PLE AND EN­VI­RON­MEN­TALLY RE­SPON­SI­BLE.

THE PROB­LEM — LAND­FILLS

A sig­nif­i­cant por­tion of food waste in New Zealand is sent di­rectly to land­fills.

Although this is the most cost ef­fec­tive way for lo­cal coun­cils to man­age food waste that peo­ple throw out, it’s not a sus­tain­able way to dis­pose of or­ganic waste.

Food waste at land­fill rapidly re­leases meth­ane which is a harm­ful green­house gas.

COM­POST­ING IS KING

Lo­calised com­post­ing or worm farm­ing is the cheap­est, sim­plest and most en­vi­ron­men­tally friendly way of dis­pos­ing of house­hold food waste.

Com­post­ing is free and en­ables nu­tri­ents to re­turn to the soil, ben­e­fit­ting your garden growth. The pro­duc­tion of us­able com­post or worm cast­ings is highly ben­e­fi­cial to the New Zealand en­vi­ron­ment and cuts down on waste to land­fills.

THE NEXT BEST THING — FOOD WASTE DIS­POSERS

Ac­cord­ing to young New Zealand en­vi­ron­men­tal­ist Brittany Packer, food waste dis­posers play an im­por­tant role in the dis­card­ing of food waste.

“Food waste dis­posers de­posit food through the pipe sys­tem into the waste water treat­ment plant… [and] it even­tu­ally ends up as biosolids, which is a thick sludge that looks sim­i­lar to com­post.” The meth­ane re­leased dur­ing waste water treat­ment is cap­tured and turned into elec­tric­ity to run the plant.

The biosolids are used for land recla­ma­tion. This is the best way to dis­pose of food waste such as meat, fish, soft bones and dairy prod­ucts, which should not be com­posted due to hy­gienic rea­sons. It is also a 100% bet­ter alternative to throw­ing any food waste in a rub­bish bin – if you’re go­ing to be lazy at least put food waste down a dis­poser! It is also ideal for com­mer­cial and apart­ment en­vi­ron­ments where com­post­ing is not vi­able.
