Ever thought about cutting scraps leftover from the manufacture of leather garments or furniture? OK, probably not, but some scientists have recently been thinking about its value. A new study in Green Chemistry (2012, Issue 2) has shown it can be recycled into a medically useful material. Leather hides (and their scrap) contain a protein called collagen, found in all mammals. Researchers were able to extract collagen from leather waste and turn it into a variety of regenerative medical items such as sutures, fibers, threads, films, gels and sponges. While more research must be done before collagen from leather could be commercially viable, this interesting study shows that high-value reusable material can sometimes be found where you least expect it.
Architect Lina Bo Bardi has given us a completely recycled factory in Sao Paulo, Brazil. The factory has been repurposed as a community space run by SESC, an organization that manages the 1.5% payroll tax that is levied for social and cultural projects (SESC is described in more detail here). The surrounding community had already been using the streets around and through the abandoned buildings as a gethering place. With SESC funding, the space has been transformed into a culture spot, called SESC Pompeia, with a theater and other performance spaces, sports area, and a library lounge, among other amenities. Way to reuse an old barrel factory, Brazil!
Not to be outdone, the Dutch are in the news this week regarding the reuse and repair of household objects and appliances. A social project as much as an environmental one, the "Repair Cafe" concept brings together skilled volunteers with people who have things that just need to be fixed (an old iron, a vaccuum cleaner, you name it). The main Repair Cafe is held several times per month in an Amsterdam community center, but its success has spawned thirty additional sites across the Netherlands and calls have come in to its managing foundation from throughout Europe with requests for information on how to start similar initiatives. As skills about simple repair of household objects have declined in this heavily service-based non-manual-labor society, the Repair Cafe project allows neighbors to pass on such skills, or at least the fruits of them, to other neighbors, all while decreasing waste-to-landfill.
(Psst, anyone in NYC want to start a Repair Cafe here? I'll be the first customer!)
