these materials saves time and money and it is much better for the environment outside the university of cape town. one professor wants to introduce that idea, not just in south africa, but across the entire continent with its resembles a meat grinder, but this machine grind subcircuits broods instead of pork. this started this part of an innovative research project in south africa. finding out how to recycle the precious bits of circuits broods can do when johnson ph is in from the university of cape town, figured out a way we were trying to crush the circuit board so that we can access the in the live for the copper that sandwiched in between layers within the board, access in the metals like copper will move valuable. gold is difficult and costly. most of south africa's eat waste is purses to overseas by companies that operate huge furnaces. it was a realisation that we have in south africa. a lot of people who just collect a few circuit boards and take them to recycle, who then just crush them up and since them overseas. and we said walk on, we process this material here, create jobs with that

how to recycle the precious bits of circuits broods can do when judging peterson from the university of cape town, figured out a way we were trying to crush the circuit board so that we can access the in the lives of the copper that said when in between is layers within the board axis in the metals like copper, all move valuable. gold is difficult and costly. most of south africa's eat waste is purses to overseas by companies that operate huge furnaces. it was a realisation that we have in south africa. a lot of people who just collect if you think it was and to take them to recycle, just crush them up and since them overseas. and we said walk on, we process the material here, create jobs with that. the challenge for the scientists finding a method where it's at a smaller scale and price point. that also does not to contaminate the environment . they developed a chemical extraction process for copper, a fiend, ammonia solution trickles through the ground of circuit boards. over the course of several days, the solution extracts the copper indicated by the blue coloring. the american mixture can be

these materials saves time and money and it is much better for the environment at the university of cape town. one professor wants to introduce that idea, not just in south africa, but across the entire continent with its resembles a meat grinder, but this machine grinds subcircuits broods instead of pork. beef is sent to the spot of an innovative research project in south africa. finding out how to recycle the precious bits of circuits broods can do when judging peterson from the university of cape town, figured out anyway, we were trying to flush the circuit board so that we can access the in the lives of the copper that sandwiched in between these layers within the board access in the metals like copper, all move valuable. gold is difficult and costly. most of south africa's eat waste is purses to overseas by companies that operate. huge ferns is also a realisation that we have in south africa. a lot of people who just collect a few boards and take them to recycle, just crush them up and since them overseas. and we said walk, we processed material here, create jobs with that, the challenge
