School project leads to nappy compost business
Relevant offers
A Christchurch girl's school science project is being developed into a business thanks to a Rangiora couple, a Canterbury firm and a multi-national company.
In 2003, Natalie Crimp, then 14, scooped an Environment Canterbury prize for her science project on composting dirty disposable nappies.
She shredded the nappies and threw them into a rotating drum with plenty of leaves, turning it regularly and ensuring it was kept warm.
Six weeks later she had compost which could be easily separated from the non-biodegradable plastic.
Last year, Rangiora couple Karen and Karl Upston, who sell cloth and disposable nappies from home, trialled a nappy composting service for disposable nappies using the same process as Natalie.
Now, in partnership with Canterbury company R5 Solutions and sponsored by Kimberly-Clark, which sells Huggies nappies, the Upstons are expanding their business and launching New Zealand's first nappy composting service.
The new composting plant using R5's HotRot technology will be able to process about two and a half tonnes, or about 15,000 nappies a day.
Parents will store their used nappies in special bags which will be collected weekly or fortnightly for a small charge.
Eventually they hope to process up to 10 tonnes or 60,000 nappies a day and have the nappies collected as part of council waste collections.
"We were surprised by the sheer number of people waiting for this type of service to be made available and willing to travel and pay for it," Upston said.
"(During the trial) we had families travelling for up to one hour in each direction to drop off their disposable nappies."
Natalie's mother, Jeanne Crimp, said her daughter, now studying at a US university, was pleased with the development.
"I think at the time, being a young person, she was a bit disappointed that something didn't happen immediately," Crimp said.
"She thought she had this brilliant idea but the grown-ups weren't jumping up and down to pick it up.
"She is pleased that something has happened now though, and has sent her best wishes George and Karen and everyone involved."
Green Party spokesman for the environment Nandor Tanczos said he was pleased to see a company like Kimberly-Clark supporting environmental projects.
While he would continue to use reusable nappies, the move gave parents another option he said.
The plant should be operating by the end of the year.

Has louise considered that cotton nappies require resources of the environment too! The soiled nappies have to be cleaned to be reused,all that matter ending up in the sewerage plant, treated then dumped out to sea. Is that really so much better. This isn't about cloth versus disposable, it's about disposables are here, we are using them and heres a great way to deal with them and get them out of our landfills. Nothing is perfect in this world and since people are going to use disposable i think it is a brilliant idea that they can be turned into compost and reused.....hence your reduce-reuse-recycle. Plus the added bonus of recycling food waste and green waste. I was part of the trial and it was amazing that coupled with council kerbside recycling i was only using a garbage bag every 3-4 weeks. Now it's a bag a week with stuff that i know can be dealt with a better way. I can't wait for this to start up again.
When would something like this be made available in the other centres throughout NZ. This is a fantastic idea and I would definitly pay / support to have one in the Auckland area. I'm positive they will be a huge success regardless.
I hope that Natalie is given a small slice of the profits as well as acknowledgement of her idea
So, are the Upstons doing the decent thing and paying royalties to Natalie for using her process??
At the time I read about her science fair project, I told myself if I ever got the opportunity, I'd buy shares in Natalie's company! It would be a shame if others profited and she got nothing for her work.

hmmm driving an hour to drop off disposable nappies (each nappy containing a cup of oil itself), doesn't sound very green to me. Remember REDUCE, reuse, recycle is the motto. Cloth nappies (despite the propaganda put out by Kimberly-Clarke, such as quoting a spurious irrelevant UK study) are still enviornmentally far superior to disposables. Not to mention easy, more effective (no leaks), cheaper (by thousands and thousands of dollars) and better for your baby ...which would you prefer, chemical goo next to your skin for 2-3 years or cotton?? How much power is used to keep the composting nappies at the required temperature?? How much fuel is used in the collection of used nappies? I use Motherease cloth nappies and can't recommend them highly enough...everyone I have "converted" has been delighted with their decision. Try them!!
Nandor Tanczos is using nappies??!

Give mothers a break - there is always so much negative press about disposable nappies and yet never do women get questioned on their use of sanitary products. Interfering good meaning people are adding to the stress of being a mother with there holy than thou attitudes and yet I am sure they don't even think each time they reach for a sanitary pad. And pity help them when in old age when we put them in cloth nappies, all soggy and wet, leaking all over their beds!!! Hooray for a composting system that means we can use technology and minimise the effects on the environment. All councils should be buying one of these composting machines and collecting nappies as part of their waste management.
