Closing the Loop FOR MOBILE PHONES

http://www.closingtheloop.eu/



Get started on circularity.

Combine unique marketing with societal benefits.

Your company uses mobile phones. We make this usage circular by offsetting your phones.
One phone you use, leads to one discarded phone being responsibly collected and recycled. One for One.

Our services turn your circular ambitions into tangible and audited results and an appealing story. Offsetting your phones makes your gadgets waste-free and material-neutral.



It works like this:


  • You buy a phone and want this purchase to be more sustainable;
  • CTL charges you a fee of a few euros per phone;
  • CTL uses that fee to pay its African partners for the collection of an end-of-life phone;
  • This collection is done by local communities in the emerging world, in a safe way that is fully in line with international laws;
  • If proper recycling is not possible locally, CTL ships the waste to certified facilities;
  • The waste is then turned into reusable materials (urban mining), in a safe and clean way;
  • You get great content, circular results and audited reporting on our approach.

Closing the Loop - Circular Economy for mobile phones (Ghana)

http://www.reinhardtsmit.com/projects/closing-loop-circular-economy-mobile-phones

Closing the Loop is a Netherlands-based organisation that creates a circular economy for mobile phones. In practise, they give good quality second hand mobile telephones a second life in Africa, but more importantly, they create a reverse-distribution system in less developed nations to collect mobile phones for recycling.

Waste printed circuit boards nonmetallic powder as admixture in cement mortar

Materials and Structures. Volume 45, Issue 10. Waste printed circuit boards nonmetallic powder as admixture in cement mortar Ru Wang, Tengfei Zhang & Peiming Wang Abstract In this paper, the nonmetallic powder recycled from waste printed circuit boards (PCBs) is used in cement mortar as admixture. The mechanical properties, bulk density, air content, water-retention property, shrinkage rate and water capillary adsorption are tested. The results show that the waste PCBs nonmetallic powder causes an increase in air content and improves the water-retention property of fresh mortar, decreases the bulk density of hardened mortar. The compressive strength and flexural strength of mortar with PCBs nonmetallic powder change slightly with the m p/m c below 15%. The tensile bond strength goes down continuously with the increase of the m p/m c but the reducing trend in the m p/m c range from 0 to 10% is slow. The drying shrinkage rate of mortar has little change as the m p/m c varies from 0 to 15%. The water capillary adsorption of mortar with the m p/m c of 5, 10 and 15% are lower than that of control. Cement mortar made with recycled waste PCBs nonmetallic powder is a new type of green building materials, which is friendly to environment and has broad application prospects.
