Leather Industry Capability Map

The Australian Industry

The Australian leather industry consists of bovine (cattle), kangaroo and sheepskin tanning industries (either part or fully processed). The overall leather industry employs around 2700 people in Australia and has close to $1 billion in revenue. The vast majority of this is from the export of pre-tanned or raw hides which in 2010 was close to $700 million.

Production

Leather is a textile product made from the skin of animals that has been chemically treated or ‘tanned’ to give it desirable properties such as resilience, flexibility and a whole range of specifications that can be required by end users.

The main raw material for leather, the skins or hides, is essentially a by-product of animals slaughtered for meat. A typical skin in its raw state is worth only a fraction of the total value of an animal, so livestock are slaughtered according to market conditions for meat rather than the demand for leather.

Australia has large herds of cattle and sheep as well as a large wild kangaroo population giving it a natural advantage in the availability, locally, of a naturally recurring raw material resource which constitutes a significant proportion of the total cost of production. Australia produces approximately 8 million cattle, 24 million sheep and 1.5 million kangaroo hides per annum based on available slaughter numbers.

However, Australian finished leather producers must compete with international manufacturers for the raw and semi-processed or wet blue hides. As overseas manufacturers can produce leather cheaper than domestic manufacturers it puts a price pressure on local manufacturers who may find it difficult to match prices for raw hides.

Australian manufacturers are subject to stringent environmental controls, and given the heavy use of chemicals in the tanning process, the cost of compliance is a real impact. Competitors in developing countries with lower environmental standards have a large competitive advantage in terms of price.

Although leather manufacturing is a capital intensive process, higher labour costs than developing countries also leads to increased costs which makes it difficult to compete on the international market.

In order to compete with lower cost countries, Australian wet blue processors have been at the forefront of developing and adopting the latest technology. This has included initiatives such as; the recycling of chrome, reducing processing times to increase productivity and the use of effluent by-products as fertiliser.

In terms of finished leather, the Australian industry has been at the forefront of developing performance leather for automotive and footwear use.

Typical Leather Manufacturing Process

Grading is done as a quality control step throughout the manufacturing process. Imperfections in hides such as punctures, scratches and scars decrease the quality of the finished product and determine the use for which it is most suitable. Throughout the process, hides are continually graded to achieve the best use of skins.

Hides usually arrive at the tannery from nearby abattoirs but at some larger and more integrated operations some hide processing is carried out on site.

Soaking and washing

The skin is soaked and washed to remove dirt and blood from the hides, as well as restoring moisture and removing salt if the hides were salted.

Liming and unhairing

By adding lime and sulphur compound the hair is removed from the skin

Fleshing

During this process tissue, flesh and fat remnants are removed

Deliming, Bating and Pickling

During bating and pickling the skins are treated with acid and salt in preparation for tanning.

Deliming removes the lime and alkaline chemicals in the limed hide. Bating involves adding enzymes to clean the grain surface and further destroy any remaining hair roots and pigments.

In the pickling stage, sulphuric acid, water and salt are added. This enables the hides to receive the tanning chemicals. The hides are in a preserved state after this step.

Pickle Grading, Trimming, Storage

Hides are graded on quality, trimmed down and stored until they can be tanned in the next step, as they are now preserved and won’t deteriorate.

Chrome Tanning

Uses chromium in the form of basic chromium sulphate. In the raw state chrome tanned skins are blue and therefore referred to as "wet blue". Chrome tanning is a fast process taking less than a day and produces a stretchable leather which is excellent for use in handbags and garments.

Australia only has a few remaining large chrome tanneries. Recent rationalisation is a result of increased competitive pressures and reduction in incentive schemes.

Firms that undertake this process include Walfertan, Austanners and Packer Leather.

Vegetable Tanning

The alternative process to chrome tanning is vegetable tanning which uses tannins which occur naturally in the bark and leaves of many plants. Hides are stretched on frames and immersed for several weeks in vats. Vegetable tanned hide is flexible and is used for items such luggage and furniture.

Sammying and Grading

Sammying involves removing water from the hides

Shaving

Leather is shaved down to the required thickness.

Trimming

The hide is trimmed to remove unwanted edges.

Retan, Dying and Fatliquoring

Dying confers a desired colour to the leather and fatliqouring involves using a chemical reagent to soften the leather, adding back some lost moisture. These processes can be seen as ‘retanning’ procedures.

Setting

The leather is laid out flat in preparation for drying.

Vacuum Drying and Conditioning

Hides are vacuum-dried to remove all moisture and conditioned.

Staking

When hides arrive at this stage of processing they are very stiff and following drying, the leather is mechanically staked in order to soften it. Further processes take place in preparation for finishing.

Crust Trimming

The leather is trimmed again.

Buffing

Hides which have been damaged and have imperfections can be smoothed by mechanical sanding to improve final appearance and assist in the application of coatings. Leathers which have undergone buffing are known as corrected grain.

Crust Grading and Storage

Leather is graded again, according to quality and stored.

Finishing

Here the leather is given its final surface treatment and look. Through processes of base coat, colouring, embossing, ironing the leather becomes, depending on the demands of fashion, matt or shiny, two-tone or uni-coloured, smooth or grained. The art of finishing lies in working in wafer-thin layers without disturbing the natural look of the leather and its characteristics such as suppleness and breathability.

Current state of the industry

Over the past 30 or so years, the leather industry has undergone a major rationalisation with only a few large operators remaining in the market. This has been caused partly by shifting global market conditions and partly by changes in government policy.

These remaining companies have been successful in competing on export markets by investing in the latest equipment and technology and being innovative in their approach to product development and marketing.

Critical and Essential Manufacturing base

Due to the nature of the leather supply chain, Australia will always have the facilities to produce raw hides and semi processed hides as early stage inputs to production. Hides are sourced from animals slaughtered for meat and the supply is largely independent of demand for leather. As hides quickly degrade, they must be processed or semi processed close to the site of slaughter, whether it is salting or wet-blue.

There has been some loss of wet blue capacity in Australia over the last decade as government incentives have decreased and presently the majority of hides are exported as salted hides.

There are only a few finished leather producers left in Australia, as Australian producers cannot easily compete on cost with imported commodity leathers. Australia’s manufacturing is based around specialty and performance leathers such as kangaroo leather, which has superior characteristics in terms of its high strength, light weight and durability.

Remaining Australian leather producers have, by necessity, developed supply chains to ensure supply of hides and chemicals. Chemical supply can be an issue though as they need to be imported and many Australian companies are price takers rather than makers so margins can be eroded.

Eating Paste, Is It Delicous?

...FACT: It’s almost healthy to eat glue Posted by Ryan Pilling on Mar 2, 2011 in Interesting Facts | 1 comment In the exciting world of adhesives, glue is the organic side of things. Technically, for something to be a true “glue” it will get its sticky quality from an animal or vegetable ingredient. The classic example is sending an old horse to the great glue factory in the sky. In fact horse hooves, along with bone, hide, and connective tissues, provide collagen as the main ingredient for glue. (in all mammals, including you dear reader, over 25% of the protein content is collagen) The process of turning pony toes into glue is, to boil it down, essentially… boiling it down. The collagen leaks out in a jelly-like form, is collected, and ground into powder. When you’re ready to make antique furniture, you mix it with a bit of water, heat it up, and you’re ready to brush it on your joins. Collagen glue like that has been used for at least 8000 years, and has only been replaced by chemical adhesives for common use in the past century. Vegetable glue, commonly called paste, is an even simpler recipe: starch and water. The starch most commonly used is corn starch, but white flour works as well. When sticking things together, the best adhesive is one that shares chemical properties of the items you want to make stick. That’s why paste works so well with paper. The starch, which is a carbohydrate, is similar to the carbohydrate cellulose that forms the paper...

Shortage of Gelatin in India

...Globally, gelatin is largely manufactured from bovine and porcine hides, porcine hides being the more preferred lot(typically about 45% of the global gelatin produce is manufactured from pig skin), on account of the lower costs and time associated. Also, pig skin doesn’t have to contend with the leather industry on account of its low quality, making it a simpler bargain for gelatin makers. Gelatin is a vital component in the manufacture of capsules, and the Indian pharmaceutical industry is currently faced with a conundrum – a shortage of this excipient. The Indian demand for the consumption of gelatin is estimated to be around 10,000 tons in 2011, and the demand is expected to grow at a CAGR of 3-4%. However, there is a severe shortfall in raw materials necessary for the manufacture of the same – bones and ossein. The Indian gelatin industry differs from the rest of the world, in the process followed for manufacture of gelatin: while most of the gelatin manufactured globally uses hides for the manufacture of gelatin, the Indian scenario makes use of crushed bones and ossein for producing gelatin. This is due to the virtual non availability of porcine hides for manufacturing gelatin in India. The porcine industry in India is a highly unorganized segment, making the hide collection process a hard proposition; and most of the bovine hides in India are taken up by the leather industry. Ergo, the Indian gelatin industry makes use of crushed bones and ossein resulting from the...

Observation of Catabolic Ability of Protease in Different Fruit Juice with Gelatin and the Optimal Operational Condition for Protease in Pineapple Juice

...OBSERVATION OF CATABOLIC ABILITY OF PROTEASE IN DIFFERENT FRUIT JUICE WITH GELATIN AND THE OPTIMAL OPERATIONAL CONDITION FOR PROTEASE IN PINEAPPLE JUICE 1. Introduction Enzyme are proteins that act as catalysts to carry out specific reaction in any bio organism. Enzymes have the capability of reducing activation energy barrier and thus accelerate the metabolic reactions. There are roughly 4000 different enzyme varieties known to man, and this is because through evolutionary history, enzymes has developed specific functions and shapes to accommodate different biochemistry processes. The shape of an enzyme determine the different substrates it is able to attach and thus created enzyme specificity (Wescott and Klibanov, 1994). Proteolytic enzymes, also called proteases are a group of enzymes that exist in plants, bacteria, animals etc. One of the common functions of proteases is protein degradation and it is doing so by break protein down into fragments and further into amino acids. The importance of proteases has been realised by recent research as its increased role in biological regulations (Perlmann et al., 1970). Proteases are prominent in tropical fruit with bromelain in pineapple, papain in papaya and ficin in Figs (Gall et al., 1994). Research of proteases has led to rapid development of its use in the food industry (F. Gibbs, 1999). Bromelain is a proteolytic enzyme commonly found in pineapple, and is typically extracted from the...

Triple Sugar Iron Agar Research Paper

...observed for the presence or lack of bubble formation (Cappuccino and Sherman 2014g). Gelatin Hydrolysis To determine the production of gelatinase, an extracellular enzyme used in the hydrolyzation of the protein gelatin, the gelatin liquefaction test is performed. Gelatin is produced by collagen hydrolysis, ad liquifies at temperatures above 25℃ (Cappuccino and Sherman 2014h). Organisms that produce gelatinase would hydrolyze the gelatin, causing it to liquify and not regain its original gel state. Organisms that do not produce gelatinase would be unable to hydrolyze the gelatin, causing it to remain in its original gel state (Cappuccino and Sherman 2014h). The gelatin hydrolysis test is performed by using proper aseptic technique to inoculate the deep gelatin tube using a sterile inoculating needle. After sterilizing the inoculating needle, the bacterial sample was obtained, and the gelatin tube was inoculated using the stab method. The tube was then incubated at 37℃ for 48 hours and before observation, was placed into the refrigerator for 30 minutes at 4℃ to test for solidification (Cappuccino and Sherman 2014h). If after 48 hours the gelatin remained solid, the culture would have been re-incubated for an additional 5 days and refrigerated at 4℃ for 30 minutes. Liquified cultures after 5 days indicate slow gelatin hydrolysis, while gelatin liquified after the original 48 hours indicate rapid gelatin hydrolysis (Cappuccino and Sherman 2014h). ...

...Where Beauty Begins Nails have always been a part of a women’s beauty care, whether it’s retro 1970s or cool 2013. The ad that I chose to analyze is for the Natural Wonder nail polish. This ad was published in The Australian Women’s Weekly on February 11, 1976. The ad shows a women’s face covered with several hands over her eyes, and all the finger nails are painted in different vibrant shades of Natural Wonder nail polish. The model’s lips are adorned with red lipstick, which enhances to the ad’s visual appeal. The color palette used in this ad is very attractive and bright, and the photography is impressive. Underneath the photo is the narration of the ad, advising that this nail polish is a revolutionary product, as it does not only make nails beautiful but strong. The use of alluring vocabulary, different sizes of fonts and concise information leaves the reader with a clear sense of how the product works. The Natural Wonder, “Where Beauty Begins” is a rational, inspiring and persuasive ad, which justifies the appeal to credibility, appeal to emotions and appeal to reason. There are two aspects which make this ad believable and credible. Firstly, its publication in the Australian Women’s weekly magazine. The Australian Women's Weekly, launched in 1933, is the most widely read magazine in the history of Australian publishing.

Should the cost of 25% of the gelatin plant be included as part of the investment in evaluating the TLG Project? If so, why so; if not, why not? Yes. Though gelatin plant has a 25% excess capacity, the operation expense should still be included in the investment in evaluating the TLG Project. Gelatin is not about to lease the 25% excess capacity, but it doesn’t mean the value can be ignored. 3. Should the $2.5 million associated with the test marketing of TLG be included in the TLG Project analysis? If so, why so; if not, why not? Yes. The $2.5 million expense on the test marketing of TLG spent in the early summer of 2012 should be considered as the initial investment of the project. 4. Should the profits attributable to sales of gelatin and pudding lost via erosion by TLG be included as an expense in the analysis of the TLG project? If so, why so; if not, why not? No. The lost via TLG erosion is not an investment of the project; it’s a result of market competition. The lost of gelatin and pudding may occur without TLG, caused by other new products, so TLG is not supposed to be responsible for the gelatin and puddings’ lost profits. 5.

Unknown Bacteria Microbiology

...Introduction Bacteria are microscopic unicellular prokaryotic organisms characterized by the lack of a membrane-bound nucleus and membrane-bound organelles. They are remarkably adaptable to diverse environmental conditions and are found in bodies of all living organisms and on all parts of the earth. The purpose of microbial biochemical tests is to identify the unique traits it yields and with that knowledge we can then categorize them in groups and specify them by scientific name. These experiments included the Triple-sugar iron agar (TSIA), Sulfur Indole Motility (SIM), Methyl Red (MR), Voges-Proskauer (VP), Citrate, Urease, Gelatin, and Oxidase Test. In order for these tests to produce reliable and credible results, the bacterium organism must be grown using strict and meticulous procedure to produce viable colonies of pure culture. Having pure culture is significant to ensure that a single type of bacteria is used for identification without contamination so tests can be run without complications or confusion. Once all these tests are performed, the unknown bacteria in this lab will be one of the following: Escherichia coli, Enterobacter aerogenes, Proteus mirabilis, Klebsiella pneumoniae, or Salmonella typhimurium. This report included the results and details to these experiments which are discussed further on.

Microbiology

...Abstract In this experiment an unknown gram-negative sample was obtained randomly to identify the possible microorganisms. Using comparative analysis several biochemical tests were performed to determine which bacterium out of the six potential unknowns was given. The biochemical tests carried out included; triple-sugar iron agar (TSIA), sulfur indole motility (SIM), citrate, urease, gelatinase, methyl red (MR) and voges-proskaeur (VP). In order to determine the microorganism characteristics the sample was first isolated using a t-streak and the colonies were gram stained to reveal its shape and morphology and then inoculated into several sequences of media corresponding with the proper biochemical test. After allowing the corresponding time for each biochemical test, data was collected to determine the unknown bacteria. The broth culture in this experiment was determined as Escherichia coli.   Introduction All organisms are divided into three domains; bacteria, archaea, and eukarya. The organisms making up domain Bacteria and domain Archaea are all prokaryotes. Although bacteria and archaea look the same, archaea is more closely related to eukarya (Madigan et.al 2009). The ability to adapt to a broad range of habitats helps to explain why prokaryotes are the most abundant organism on earth. The main characteristics of a prokaryote include, no nucleus, circular DNA, and no membrane bound organelles. A key feature of nearly all prokaryotic cells is the cell wall, which maintains...
