UNIDO publishes study on Sustainable Leather Manufacture
The tanning industry is a key sector in UNIDO’s mission to promote sustainable development. Since the late
1990s, a number of studies dealing with cleaner tanning methods have been published to help prepare
different kinds of training programmes for the industry, including the widely used paper “The Scope for
Decreasing Pollution Load in Leather Processing”.
Since then, new tanning technologies have been developed and implemented, accompanied by new
challenges. UNIDO considers proper training as an essential precondition for modern, sustainable leather
processing and has prepared a new study – a comprehensive paper on cleaner leather technologies which
rounds up and updates earlier papers. The aim is to assist with training and capacity building activities.
This comprehensive study addresses traditional cleaner technologies topics such as pollution sources/loads,
water management, hair-save liming, low or ammonia-free deliming, chrome management, low-organic
solvents finishing, solid waste as well as issues relevant to the performance and successful operations of
tanning activities: environmental management systems (EMS/CSR), Restricted Substances Lists (RSL),

energy considerations, Occupational Safety and Health at workplace (OSH), Carbon Footprint (CF) and Life
Cycle Analysis (LCA). So the paper tackles much of the current international debates.
For the time being, the study is published as a working paper, open to further corrections and modifications.
The final document should serve as a basis for developing globally accessible eLearning courses on
sustainable leather manufacture.

Shoe News: Pleasure or Pain opens at V&A
Shoe News: Pleasure or Pain opens at V&A
London’s Victoria & Albert Museum unveil a new exhibit that spotlights extreme footwear. “Shoes:
Pleasure and Pain” opened on June 13 and will run through Jan. 31, 2016.
Shoes worn by or associated with celebrities, including Marilyn Monroe, Queen Victoria, Sarah Jessica
Parker and Daphne Guinness, will be part of the exhibition. The work of 70 designers, from Manolo Blahnik
and Jimmy Choo to Christian Louboutin and Roger Vivier, will be on display, while newer names, like
Sophia Webster, will also be in the spotlight.
The exhibit will cover two floors. The ground-floor gallery will showcase three themes: transformation,
status and seduction. “Transformation” will present shoes that explore concepts of myth and legend, opening
with different cultural interpretations of the Cinderella story from across the globe. “Status” will take a look
at impractical shoes that have been worn to represent privileged and leisurely lifestyles — their design, shape
and material can often make them unsuitable for walking. “Seduction” highlights shoes that express sexual
empowerment or pleasure.

Research project examines antimalarial foams for footwear
Research project examines antimalarial foams for footwear
Research centres and a private sector partner in Spain are working together to create new foam applications
for footwear with antimalarial properties. They have said possible applications include special sandals or
soling materials for other types of footwear that can help prevent the spread of malaria and other conditions
such as Dengue fever, Chagas disease and Leishmaniasis.
Central to the idea, which is being developed by Valencia-based plastics institute Aimplas, a research team
from the University of Zaragoza and specialist microencapsulation company Inesfly Corporation, is to
encapsulate insecticide substances into foam using microcapsules for footwear to act as a repellent against
the insects that can spread each of these conditions.
The researchers have said they believe using microcapsules will prevent degradation of the insecticide
substances during manufacture of the finished product and will make it easier to manage the release of the
substances during wear. Their two-year project, called Inmaplesp, has secured funding from Spain’s
economy ministry.

Puma develops cooling technology with Jamaican athletes
Puma develops cooling technology with Jamaican athletes
Puma has unveiled a new cooling technology, PWRCOOL which it will incorporate into a collection
of thermo-regulated apparel and footwear. PWRCOOL footwear products feature a ComfortTemp tongue
liner which uses a cooling print on the inside that activates with moisture. The collection is designed with
CoolCELL wicking materials while anatomically placed air flow features offer temperature regulation. Puma
tested the system with Jamaican athletes including Olympic medallist Hansle Parchment, who said: “Living
and training in Jamaica is a wonderful thing, but the heat is challenging and at times pretty exhausting.
PWRCOOL is a great technology to help counter that; it works well in both the shoes and training wear.”

Chinese company launches first 3D foot scanner and 3D printed shoes
Following in line with this goal Jiaodu has created a small scanner which can be installed in a shoe store that
is operated over the cloud, sending foot scan data directly to the company allowing them to fabricate a 3D
printed shoe that is sized perfectly for the customer.
In just 3 seconds, the scanner can analyse a user’s foot, creating all the data necessary for the manufacture of
shoes. The user then selects a style and the shoes are 3D printed and shipped direct to their door for the cost
of a few hundred dollars. Currently there are 10 shoe models available to purchase, but the company plans to
unveil more models in the near future.

Italy - Leather production worth €5.3 billion in 2014
Tanners in Italy produced 126.7 million square-metres of leather and 32,500 tonnes of sole leather in 2014.
The combined value of all this material was €5.3 billion, of which just over €4 billion came from buyers
outside the country. These figures represent an increase in value of 1.5% and a decrease in volume of 1.7%
compared to 2013, reports international news site Leatherbiz.
Of the total, 79% of Italian leather was made from bovine raw material, 20% from sheep or goats and 1%
from the hides and skins of other animals.
By volume, footwear’s share of the material was 43.2% (a decline of 2.3%). Leathergoods manufacturers
took a 25% share of the material, an increase of 1.4%, while companies in the furniture sector reduced their
consumption to 15.5% of the total, down by 8% compared to its share in 2013. With regard to the automotive
industry, 9.5% of all of Italy’s leather went into automotive interiors in 2014 and this market segment
increased its share by 5.6%. Garments and gloves account for the rest.

Innovative new polymeric softening and filling retan from TFL
After the successful launch of Magnopal IPF in 2013, TFL has now developed a further product based on the
same innovative polymeric filling technology.
Magnopal IPR combines a pronounced filling effect with softening and some retanning features, which are
evenly distributed over the structure of the hide or skin. It can help to simplify wet-end application recipes by
reducing the amount and number of traditional softening, retanning and filling agents required.
Leathers produced with this polymeric retanning agent feature good heat-resistance, lightfastness and very
good hydrolysis properties. No negative effects on physical properties have been observed.
Magnopal IPR can be used to produce a wide range of leathers based on wet-blue or wet-white; from soft
articles, such as garment, upholstery and automotive leathers, to firmer types such as shoe upper and leather
goods. Milled nappa shows a more uniform break; leathers are soft and light with reduced specific area
weight. They show a level dyeing with minimal shade weakening.
It is free of formaldehyde and does not contain chemical substances which are restricted by any major
chemical regulation.

Indian researchers convert fleshings into soling material
Indian researchers convert fleshings into soling material
Researchers in India have developed a use for the fleshings from tannery waste, converting them into a
material that can be used to make soles, reports international news site Leatherbiz.
The Central Leather Research Institute discovered that the activated carbon from fleshing waste contains
calcium and can be used as filler in rubber-making.
“Leather processing generates 700kg of solid waste for every tonne of skin/hide processed. Fleshing
contributes to 10% of the total solid waste. In other words, world over, for every 100 tonnes of hide
processed every day, 10 tonnes of fleshing waste is generated,” they said. “In India, 0.9 billion kg of raw
hide/skin is processed annually. This amounts to 90,000 tonnes of fleshing waste generated every year.”
The conventional disposal methods of limed fleshing includes manufacture of industrial gelatin/protein
hydrolysate, glue, biomethanation and the remaining limed fleshing waste is dumped into landfills.
“In rubber-making, carbon black is used as reinforcing material. The conventional activated carbon do not
contain cross linking agent like CaO, so it cannot be used as filler in rubber manufacture in the place of
carbon black. In this study, we have converted the limed fleshing waste into activated carbon and since it
contains calcium it is used effectively as filler in the manufacture of rubber.”

TFL launches new high astringent tanning agent
TFL launches new high astringent tanning agent
With tight and compact leather articles in mind, TFL launched a liquid astringent tanning agent with high
tanning capacity, Sellatan Hat Liz. TFL claim, “This new synthetic tanning agent helps to deal with
challenging raw material quality to produce tight and compact leather articles. These special properties make
the product unique in the TFL range. As a retanning agent for chrome and chrome-free leathers, it allows
tanners to produce quality leathers with consistant results. It provides exceptional fullness with a tight,
uniform grain break for shoes, handbags and automotive articles. Tight grain and fullness are also
prerequisites for excellent embossing results optimising cutting yield.
The product is aimed at the production of tight and compact metal-free leathers as it contributes very little to
the formaldehyde content in the final leather. The low formaldehyde and phenol content and the minimal
TDS contribution make Sellatan ideal for the TFL White Line Technology.”
