An interview with Lior Ben-Ami, 18, inventor of the SmartSort bin

Last month, Lior Ben-Ami, a high-school student from the north of the

country, won first prize at a national young scientists' competition for

SmartSort, a bin that sorts recycling by itself. We met him in his parents'

garage, which over the past two years has become his workshop.

How did the idea come about?

"Honestly, it began with an argument. At home we have four different

bins – for plastic, paper, glass and everything else – and my younger

brothers kept throwing things into the wrong one. My mum would get annoyed

and take everything out again. I thought: if people can't be bothered to

sort their rubbish, maybe a machine can do it for them."

How does SmartSort work?

"There's a small camera inside the lid. When you drop something in, the

camera takes a picture, and a program compares it to thousands of images it

has learned from. Within about a second, it identifies what the object is

made of, and a little flap directs it into the correct compartment. At the

moment it's accurate about 94 percent of the time."

That sounds complicated. Did you know how to do all this?

"Not at all! I knew some basic programming, but nothing about machine

learning. I followed online courses for months, and I failed again and

again. My first version was convinced that every bottle was a banana. I also

photographed more than 8,000 pieces of rubbish myself to train it. My family

thought I'd lost my mind."

What was the hardest part?

"Persevering. There were weeks when nothing worked and I was tempted to

give up. My physics teacher kept reminding me that every failure is just

more information. That sentence really helped me."

Do you think a machine is the real solution?

"Not completely. SmartSort can help, but the best rubbish is the rubbish

we never create. If my bin makes people stop and think about what they throw

away, that's already a success."

What's next?

"A company has offered to help me develop SmartSort further, but I want

to finish school first. My dream is to make a cheaper version for schools,

because that's where habits begin."
