In 】recent y【ears, ra/ising awareness around the\ ecological impact o】f producin/g le】athe】r i/tems】 has prompt\ed a gro【w】】ing number of brands to rec\onside】r their u【se of the fa【bri】c in】 th】e/ir fashio【n lines/, as well as it has【 pushe/d new actors to \co】me up w\ith innovative solutions to creat\e more ecol【og\ically-【fr/】iendly le\ather/.The ec】ologica【l cost of leather productio】nT/he initial r】aw\ material for l\eather 【producti】/on is animal【 skin\ which orig【inates from ani】mal farming, a pro】ce\ss w\h【ich】 【usually rel】ie【s on huge amounts of feed, pasturel/and【, water, and】 fossil fuels with ne/gative ecologic\al impacts. However, leathe【r /is 】on】l】y a by-pro/duct in thi】s process, the animals being primarily raised for their me\【at/.Where/ the e【nvir【onmental cos/t of leat】her product\io\n really beco】mes visibl【e is at the /stage of the\ transformatio【n of the animal skin into the f】inal prod/uct. Since /leather is a perishable material, a number 】of methods have been used to st【abi【//lise t\【he raw mate【ri\al, and make it m\ore durable via t/h【e tanning process.This 】】is an indus【trial process that【 typically involves 【many ch\e】mical com】pounds and uses up a lot of water and energy. A number of hazardous mat\eri/】als a\nd /p】ollutants are/ releas\ed i】n 】the envir【onmen【t s\uch 【as mineral salts, lime slud】ge, sulfides, fo\rmaldeh\yd\e, coal-tar de/ri【vatives, a】nd various oil【s, dyes, and finishes (some o/f them cyani【de-bas【ed) are employed. . Water \i】s u【sed in】 high quantit】【y as a s/olvent, which is all the more problematic that a significa【nt n【umbe\r of tan【neries/ are lo【cate】\d in ar\id regions \of the world.To a】ddress these i【ssues, \the dev\elopment of new technologies t【o\ 】provide】 more ef【fici\ent processes for【 the pr\oduction of le】ather【 is under】way. So are efforts to promote the production of synth】etic leath\e\r, /w/hi】c/h could offer an interes【ting【】 alternative to th【e fas/hi【on indu【stry.Cow lea】\ther vs synthetic leatherFor 】change 】to happe】n in the leather i/ndustry tho】ugh, rob/ust assessme/nts of t\he/ dif/feren】t m】ethods us\ed in the ta【nn】ing process/ and compari\sons betw【ee\n cow lea】ther an\d other materi】als, are ne【ed\ed.Researchers have assessed the e【cological impact of different ta【nning methods to se【e if on【e was prefe】rable in t【】erms of its environment/al footprint.】 One o】f the techniques 【that some tanneries \employ to reduce the u【se\ of harmful che】micals is to 】resort to vege/table-tann【i【ng.This is an artisanal process that tak/【es advantage of /the t】an【ni\c acids na【】turally found i/】【】n some pl\】ants, by using the/ barks, branches,】 lea【ves or even s】\ome fruits in s/ome specific te\chniques. 【It is /【t\houg【ht to be more 【environmental/ly friendly than oth/e/r methods of processing /cow l\eather.To find out more,/ a 2017 stu【dy comp【a\r/ed this 【m【eth/o/d to more t\radit\ional 【methods using chemi】\cals suc\h a【\【s c/hromium-】/tanning, looking at th\e carbon, water, and energy 【footprint o\f the vege】\table】 】and chromium leather pro】ces/sing 】technology in 12 selecte/d tanneries in seven dif/ferent coun】/tries worldwide.The scientists act【【u】a【lly fo【und no sign/if【ican】t d\iff【erences in the fo【otpr【int of vegetabl/】e 】and chromium leather processes. Ho【wever, they cauti】on that this type of research is /challenging to do and /that tak/i】ng steps to improve the leather ind/ustry need to be base\d\ on evidence\-based resea\r【ch.“\Each tannery proved to be 【very individual, a\nd the\refore 】att【empting to pe/rform this type of analysis /without si【mply producin/g【 meaningle【ss generalities is 【a cha\llenge\ f【or companies, researcher\s, and regulator/s,&r】dquo; the 】researchers say. While【 /there is/\ little evide\nce \then that cho】osing a spec\ific m【ethod of leather tanning may be 【bette\r fo【】r the environment, \the evidence in favour of producing syntheti\c lea\ther ins】tead of leat】【her from /an\imals i\s mounting.Th】e 201】【 Pulse of T【he 】Fash/ion Industry Report published by the Global】 Fashion Agenda and The Bos/ton Con/\s】ult【ing Grou/p, was instrumental in highlig【ht【ing the\ idea that the prod】uctio/n/ of 】synthetic leather i\s less d】amaging /to the \environment/. It offer/ed 【some \of th【e most robus【t 】conclusions 【o】n th/e subject to date,】 p【ro】mpting\ 【stake】holders in the】 fashion indus/t\ry to switch to more ecological options, including synthetic leat【he】r【.Th】e /rep】o【rt indee\d/ showed \that among /all the materia】ls used in the fashion \ind】ustry, an】imal leather ranked thi【rd as the main contributor to global\/ warmi\ng. I【t also came first as the 【most damaging mat【erial/ when resea\rchers looked 【at th\】e issue of eutrophicat【】ion : its man【ufa】ctu【re was【 associated w】ith a relea/se of excessive chemical compounds and nu/trients/ into bodi【es of w】ater, frequently due to runoff from】 th【e land, causing\ dense growth of plant l\if【e\ and deat\/h /of 】anima【l\ life from lack of 【oxygen.More impor】tantl【y, the report found that synthetic leather /had on average on】ly /【a third of the environme】n】tal \impact of【【 cow leather. 】Switching to/ alternative materi】\【/a\/ls, including synthetic leather【, could thus directl\y improve a p\roduct&rs【quo;s 】ecological foot/prin】t.Gro】wing number of initiativesThe \mes【s【age【 has progressively\ been recei\ved\ and a growing numbe\r of initiatives i/llustrat】e the mo/ve to abandon cow l】eath】er for its synt】hetic a【lternatives.
