UNIDO has prepared and published over one hundred publications, papers, manuals and guidelines, primarily aimed at technical experts and policy makers in developing countries, though many are used by sector-related institutions and development organizations elsewhere.

The website www.leatherpanel.org is intended to provide an easy access to information sources on the leather, footwear and leather products industry, as well as to UNIDO publications related to the leather sector in one place, including earlier publications that were previously only available in hard copy.

Conventional technologies for treatment of tannery effluent are generally energy & chemical intensive and continuous process monitoring and control are required to achieve optimum results. In search for alternatives, robust, easy to operate and low maintenance technologies, constructed wetland system, also known as root zone treatment system, using reeds for treatment of effluent, has been considered a possible option. This system is widely used in Europe and elsewhere to treat municipal sewerage. However, there was no practical experience, at least at semi-industrial scale, about its applicability in purification of tannery effluents. Accordingly, in cooperation with willing tanneries and management of common effluent treatment plants (CETP)  in Tamilnadu, India, UNIDO, under its Regional Programme, established four pilot and demonstration reed beds, each with different features, to deal with effluent of different characteristics. Practical experience and results are reported in this paper.

The objective of this survey is to provide a review of domestic and export trading patterns inside footwear business and to give recommendations to developing countries for using appropriate trading strategies and channels. The focus is on footwear marketing and sale. The structure of this paper follows the development we have seen inside sale and marketing of footwear. The paper refers from the beginning less than 150 years ago with local supply of footwear up to day where footwear has become an important business on the global market place. The development has been different from one continent to the other, but it is important to realize that the consumer has become a powerful player. To know and to acknowledge the customers wishes is and still will be a key factor. The development has created challenges. A lot of new markets have come and the competition is growing every day. The paper describes the most important challenges. Challenges, the footwear business has to be aware of. The paper tries to give an answer to the questions the challenges bring.

The objective of this survey is to provide an independent and reliable review of the Chinese footwear industry and trade.

This study 
• assesses the scale of the industry and how it achieved its present size and status; 
• describes the industry as it is today in all its various facets such as ownership, labour availability etc.; 
• considers how much further the Chinese footwear industry is likely to grow and whether there is some equilibrium point it will reach and if so what that is likely to be and when this 
will happen. 

The survey was presented during the 15th UNIDO Leather Panel held in Leon/Mexico 2005.

Towards the end of the 20th century the tanning industry has made a considerable progress in controlling the environmental pollution caused by its activities, yet the situation varies from country to country and even from region to region within some large countries. Some tanners in industrialized countries hold the view that lax environmental regulations and poor enforcement account for lower production costs, higher competitiveness and hence further expansion of the tanning industry in developing countries.

This study compares the costs of treatment of tannery effluents, including indicative investments costs in selected industrialized and developing countries. While the figures concerning the investment and operational costs by now are quite obsolete and technologies change, the comparisons of the cost structures are still quite elightening.

The requirements of leather users and consumers need a definition of each of the properties and means to control raw materials, processes and the quality of finished products, as well as of leather articles. Quality and quality control play an important role and are the corner stones on which the good reputation of leather, tanners, leather products manufacturers and traders are built. As the distinction between countries supplying essentially raw materials and countries producing leathers on an industrial scale becomes less clear, the developing countries, once exporters solely of raw hides and skins, are encountering growing pressure to improve the quality of their emi-processed and finished leathers and of products made of leather. Publications were presented during the 12th UNIDO Leather Panel held in Teheran/Iran (1995).

Machines and mechanical equipment play an important role in modern tanneries. Though these results in increased productivity, their use has also introduced new hazards into the tanneries.

One element of OHS, which is contained in the knowledge and expertise of the workforce, is the skill of re blading.

Malpractice and lack of knowledge in this area, have initiated the manufacturing of the manual presented in this report. This report is prepared as a manual for re blading of cylinders, for the use in ttanning industry.

UNIDO has been dealing with specific problems of the leather industry more than four decades since its early years. The projects have focused on improving capabilities and performance in the collection of hides and skins, in leather processing (tanning), and in the manufacture of footwear and other leather products (such as leather goods, gloves, leather garment, upholstery and sports goods). Most successful programs in the leather sector: Environmental protection and pollution control including industrial safety directly related to leather processing and leather products manufacturing through the: ▪ Waste minimization and conversion of solid wastes into saleable by-products. ▪ Design, construction, and operation of tannery Effluent Treatment Plants (ETPs) with particular emphasis on common, low cost systems for SME clusters (CETPs). ▪ Handling and safe disposal of solid wastes and sludge. Direct assistance to industrial units and developing human resources by: ▪ elaborating and implementing comprehensive professional training systems; ▪ establishing and/or rehabilitating national, (sub)regional and international training-cum-service institutions; ▪ implementing experts meetings, workshops, seminars and special training courses in design, technology and management related areas; ▪ initiating, organizing and monitoring cooperation among training, service and Research & Development centres operating in developing and industrialized countries; ▪ benchmarking and evaluating business opportunities, finding or establishing markets (niches), building product ranges, improving production methods and product quality, enhancing productivity, and developing labour and managerial skills. Global forums – UNIDO Leather and Leather Products Industry Panel and publications: ▪ The main objective of the Leather Panel is to elaborate topics and to produce discussion papers for the consultations, but also as tools for the project implementation (e.g. training material, various publications etc.); ▪ Leather Panel members is an unique mixture of 16-22 reputed specialists in leather processing (tanning), footwear and other leather products manufacturing, equipment suppliers, distribution (trading), related pollution control, quality testing and training institutions working in private companies, Government agencies and trade associations, various types of institutions, trade press; ▪ Several documents produced for and discussed in panel meetings are now used as reference materials worldwide (e.g recent Carbon Footprint study for the leather industry presented during the 18th LPM); ▪ The panel is also very useful for preparation of project proposals/ideas and establishing contacts between UNIDO and relevant leather organizations; ▪ Global forums, e.g. Leather Panel, publications, Expert Groups Meetings provides UNIDO much needed visibility. The Main strengths, advantages and features of the UNIDO Leather operations are: □ technical orientation in formulation and execution/implementation of assistance programmes addressing problems on the "shop-floor level" and offering practical solutions in product development, technology, production control and marketing; □ integrated programme approach on the global, sub/regional and national level in addressing the actual needs of developing countries in technical assistance, i.e. providing services dealing not only with the mainstream of the technology, but also giving sufficient attention to the sectoral strategies, (physical and human) infrastructure, support industries, environment protection (including legislation), marketing and management; □ output orientation providing visible and measurable results in the assisted production units and institutions; □ direct involvement of staff members in projects by performing specific expert's jobs as well as authors/lecturers in international scientific meetings, congresses etc; □ pilot solutions that bring about the much needed multiplication effect and that are applicable beyond the direct recipients' plants; □ extensive training of recipients of TA in different forms: on-the-job, national/regional, workshops, panel discussions; □ practical technical papers, manuals, guides, and studies on specific issues in the sector.

The objective of the study prepared in 2007 for the 16th UNIDO Leather Panel was to evaluate the continuous growth of the China/Vietnam competition in the footwear sector, to assess the situation of the industry in the rest of the world, to come up with possible future scenarios and to propose strategies/actions for enhancing the competitiveness of developing countries. 

Under the Regional Programme for pollution control in the tanning industry in South-East Asia UNIDO has been actively looking for methods to improve conventional treatment processes which simultaneously reduce the nitrogen content and give the possibility of dealing with TDS/chlorides present in the effluent. The following technologies relating to the issues mentioned were implemented in pilot demonstration units:

  •  Mechanical/manual removal of excess salt from wet salted hides and skins
  • Reverse osmosis (RO) of treated tannery effluent
  • Improved solar evaporation
  • Carbon dioxide (CO2) deliming in a small scale tannery to reduce ammonical nitrogen
  • Constructed wet land treatment system (reed beds) possibly resulting in nitrification/denitrification
  • Ultrafiltration

A study with preliminary estimates of costs of multistage evaporation system to recover salt from reject generated by RO has also been prepared.

In another study, the scope of replacement of secondary clarifier in the biological treatment stage by ultrafiltration has been assessed. (Mladen Bosnic, December, 1997).

This report deals specifically with ultrafiltration.

The publication by the United Nations Industrial Development Organization (UNIDO), “Making private standards work for you: A guide to private standards in the garments, footwear and furniture sectors”, outlines a strategic approach for suppliers in developing countries. Private standards, also known as business values, norms, ethics, codes, principles or morals, are considered to be one of the ways of promoting social development and environmental sustainability in global value chains. Some estimates suggest that more than 1,000 codes of conduct and management systems exist. But most companies in developing countries do not have much tangible information. The guidebook was funded by the Norwegian Agency for Development Cooperation (Norad) and developed in collaboration with the Dutch Centre for Promotion of Imports from developing countries (CBI). The guidebook is available in English, French and Spanish, and can be downloaded here: www.unido.org/privatestandards
