Waste management is the collection, transport, processing, recycling or disposal, and monitoring of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste management is also carried out to recover resources from it. Waste management can involve solid, liquid, gaseous or radioactive substances, with different methods and fields of expertise for each.
Waste management practices differ for developed and developing nations, for urban and rural areas, and for residential and industrial producers. Management for non-hazardous residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator.
Waste management concepts
There are a number of concepts about waste management which vary in their usage between countries or regions. Some of the most general, widely-used concepts include:
- Waste hierarchy – The waste hierarchy refers to the “3 Rs” reduce, reuse and recycle, which classify waste management strategies according to their desirability in terms of waste minimization. The waste hierarchy remains the cornerstone of most waste minimization strategies. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste.
- Extended producer responsibility – Extended Producer Responsibility (EPR) is a strategy designed to promote the integration of all costs associated with products throughout their life cycle (including end-of-life disposal costs) into the market price of the product. Extended producer responsibility is meant to impose accountability over the entire lifecycle of products and packaging introduced to the market. This means that firms which manufacture, import and/or sell products are required to be responsible for the products after their useful life as well as during manufacture.
- Polluter pays principle – the Polluter Pays Principle is a principle where the polluting party pays for the impact caused to the environment. With respect to waste management, this generally refers to the requirement for a waste generator to pay for appropriate disposal of the waste.
Traditionally the waste management industry has been slow to adopt new technologies such as RFID (Radio Frequency Identification) tags, GPS and integrated software packages which enable better quality data to be collected without the use of estimation or manual data entry.
- Technologies like RFID tags are now being used to collect data on presentation rates for curb-side pick-ups which is useful when examining the usage of recycling bins or similar.
- Benefits of GPS tracking is particularly evident when considering the efficiency of ad hoc pick-ups (like skip bins or dumpsters) where the collection is done on a consumer request basis.
- Integrated software packages are useful in aggregating this data for use in optimisation of operations for waste collection operations.
- Rear vision cameras are commonly used for OH&S reasons and video recording devices are becoming more widely used, particularly concerning residential services and contaminations of the waste stream.
Education and awareness
Education and awareness in the area of waste and waste management is increasingly important from a global perspective of resource management. The Talloires Declaration is a declaration for sustainability concerned about the unprecedented scale and speed of environmental pollution and degradation, and the depletion of natural resources. Local, regional, and global air pollution; accumulation and distribution of toxic wastes; destruction and depletion of forests, soil, and water; depletion of the ozone layer and emission of “green house” gases threaten the survival of humans and thousands of other living species, the integrity of the earth and its biodiversity, the security of nations, and the heritage of future generations. Several universities have implemented the Talloires Declaration by establishing environmental management and waste management programs, e.g. the waste management university project. University and vocational education are promoted by various organizations, e.g. WAMITAB and Chartered Institution of Wastes Management. Many supermarkets encourage customers to use their reverse vending machines to deposit used purchased containers and receive a refund from the recycling fees. Brands that manufacture such machines include Tomra and Envipco.
The footwear industry is a manufacturing sector which utilizes a wide variety of materials and processes to produce a range of distinctly different products, from sandals to specialized safety footwear. Shoes are designed to fulfill an array of consumer requirements relating to function and fashion, and incorporate varied range of designs and styles. In addition, a range of distinctly different materials such as leather, synthetic materials, rubber and textile are commonly used in shoe manufacturing.
These materials differ not only in their appearance but also in their physical qualities, their service life, the different treatment needs as well as their recycling and recovery options at the end of their useful life. There are approximately 40 different materials used in the manufacturing of a shoe1. For example, Figure 1 represents the average composition of a typical men’s shoe which has been measured after grinding. These variations in designs, styles and materials, together with the environmental and economic implications of end-of-life shoe processing determine the feasible approaches to deal with this rapidly increasing waste stream.
Over the last 20 years, the footwear sector has placed significant effort in improving material efficiency, as well as eliminating the use of hazardous materials during the production phase. However, the environmental gains made in production are being overtaken by the negative impact of the considerable increase in the demand for footwear products.
Worldwide footwear consumption has doubled every 20 years, from 2.5 billion pairs in 1950 to more than 20 billion pairs of shoes in 20052 (see Figure 2). As a result, the worldwide per capita consumption of footwear has also considerably increased, from 1 pair of shoes per year for every person in the world in 1950 to almost 2.6 pairs of shoes in 2005. In the European Union, footwear consumption has increased by 22% from 2002-2005 to reach 2.3 billion.
Pairs of shoes3. However, the per capita figure differs significantly between each country4 (see Table 1). Although China has the highest footwear consumption in the world, the United States is the country with the highest per capita shoe consumption, since each inhabitant purchase an average of 6.9 pairs of shoes every year. At the other extreme, in the less developed countries, the per capita figure is 0.6 pairs for India and 0.5 pairs of shoes for Vietnam (which means one pair of shoes for each person every two years).
This rapid growth in shoe sales has also resulted in a significant increase in post-consumer footwear waste. In the EU, it is estimated that the waste arising from post-consumer shoes will reach 1.2 million tones per year. The retail figure for 2003 indicated that around 338 million pairs of shoes were sold in the UK. Based on this figure, it is estimated that the waste arising from post-consumer shoes reached 169,000 tones. In addition, it has been estimated that the total arising of textile and footwear waste is approximately 1,165,000 tones per year in the UK, while the amount of textile waste reused or recycled annually I estimated to be 324,000 tonnes5.
Based on a Department of Trade and Industry (DTI) study, about 9% of all recovered post consumer textiles are sold as second-hand shoes6. This indicates that around 29,160
Tones of post-consumer shoes are collected each year for direct reuse in the UK or for exportation to developing countries. However, it is estimated that approximately 10% of the collected secondhand shoes are not suitable for reuse due to their condition, and consequently end up in landfill Therefore, based on these estimates, approximately 15% (26,244 tones) of post consumer shoe waste in the UK are collected and re-distributed as second hand shoes, while the rest (85% or 142,756 tones) are disposed of in landfills. Waste disposal is increasingly regulated within the European Union. At the same time, waste management costs are increasing. With regards to waste management, the footwear industry needs: – guidelines in order to better anticipate future regulations and deal with them effectively, – a tool in order to estimate the effectiveness of the waste management. This European Standard incorporates such a tool, designed specifically for the footwear industry. In order to improve the waste management, the footwear manufacturer should perform the following tasks:
- reduce the quantity of waste,
- reuse the waste,
- recycle the waste,
- incinerate and recover energy from the waste,
- treat the waste.
This document could be used by a company that wishes to implement the EN ISO 14001:1996 management system standard.
This document specifies the process steps which are involved in the generation of the waste from footwear manufacture and the usual waste management practices. It also establishes a European list of the usual wastes generated during the footwear manufacturing process. It can be applied to one specific product, a specific group of products, and one specific production technology within the factory or to the whole production of a company.
Unsustainable consumption and production patterns in the developed world have led to an increased generation of waste over many decades. Although local and national authorities, governmental agencies, manufacturers and the general public have come to recognize the importance of controlling waste at source, total waste elimination is not possible. There will always be some waste that cannot be prevented at source and so need to be treated at the end of its functional life.
Considering the amount of end-of- life (EoL) waste generated every year, understanding and developing methods for EoL management is a major part of the overall waste management concern. The footwear industry over the last years has placed significant effort in improving energy and material efficiency, as well as eliminating the use of hazardous materials during the production phase. However, the environmental gains and energy efficiency made in production are being overtaken by the considerable increase in the demand for footwear products, the so called rebound effect .
Moreover, the useful life of shoes is relatively short and progressively decreasing as a result of rapid market changes and consumer fashion trends. This creates a large waste stream of worn and discarded shoes at the time their functional life has ended, and most of them are being disposed in landfills. Producer-responsibility issues and forthcoming environmental legislations, as well as increasingly environmental consumer demands, are expected to challenge the way the footwear industry deals with its EoL products.
The footwear industry is a diverse manufacturing sector which employs a wide variety of materials to make products ranging from different types and styles of footwear to more specialized shoes. Leather, synthetic materials, rubber and textile materials are amongst the basic materials most commonly used in shoe manufacture; each material has its own specific characteristics. Materials significantly influence, not only the life of the footwear but also the end-of-life treatment of the product.
Approximately 40 different materials can be used in the manufacturing of a shoe nowadays; the shoe industry is facing many of the same challenges as the consumer products and food industries. To meet the needs of customers and be competitive, footwear companies must face two key challenges: being quick to market changes and stay relevant in order to identify or establish new consumer trends. This leads to a shorter life cycle of shoes, and an even increasingly shorter product development cycle for the footwear industry. A shorter life cycle of shoes means that more shoes have been produced over the years, so leading to a higher level of EoL waste by the footwear industry.
From 1990 to 2004, worldwide footwear production has increased by 70% to around 17 billion pairs of shoes while by 2010 experts in the sector expect the global footwear output to reach 20 billion pairs. Shoe production and consumption is definitely rising. Western Europe and United States consume 2 billion pairs of shoes each every year. In the UK alone, more than 330 million pairs of shoes, with a total market value of more than £5 billion are consumed every year.
Proper disposition of a discarded or discharged material in accordance with local environmental guidelines or laws.
Final placement or riddance of wastes, excess, scrap, etc., under proper process and authority with (unlike in storage) no intention to retrieve. Disposal may be accomplished by abandonment, destruction, internment, incineration, donation, sale, etc.
Processing and or removal to final resting place or transfer to a place for re-use or recovering of waste.
The process of getting rid of unwanted, broken, worn out, contaminated or spoiled materials in an orderly, regulated fashion.
The act of getting rid of unwanted items and material having no value in excess of their basic material content. Mixed municipal solid waste (MSW) is typically disposed of at landfills, mixed-waste composting facilities, or energy recovery facilities. The removal of unwanted materials left over from manufacturing processes or people’s lifestyles.
Proper waste disposal involves following the supplier’s instructions found on the MSDS for each material. Also, soap makers may contact a recycling center to ask if it will accept old essential oils, fragrance oils, rancid base fats, fixed oils, curdled soap batches, and etc.
Disposal is the management of waste to prevent harm to the environment, injury or long term progressive damage to health. Disposal of waste is where the intention is to permanently store the waste for the duration of its biological and chemical activity, such that it is rendered harmless.

Waste from Shoe Supply Chain
Material Input and Waste Diagram
The largest quantity of waste is generated at the cutting process. E.g. waste rate from cutting of natural leather (e.g. cow hide) = 25 – 35% (14th Meeting of UNIDO Leather Panel, 2000) a leather skin is never homogenous and rectangular the quality of the leather at the side of the skin is generally poor.
The shape of the pieces to be cut is scarcely the same and the production delay does not allow the optimization of their arrangement for textiles or fabric, cutting waste is generally lower because the material is more homogenous = 20 – 25%
Waste from upper = 132.6 tons/M pairs
Waste from sole = 118 tons/ M pairs
Adhesives, oils, solvents = 4.6 tons/ M pairs
Household type waste = 10.8 tons / M pairs

Integrated Waste Management
Footwear Wastage Management in Bangladesh
Though proper wastage management in appeared to be economical for any industrial production, practice is not been so familiar in footwear industries in Bangladesh. Only a few leading companies introduced this approach for some of their production facilities.
Wastage and disposal methods
Leather Materials: wastage from shoe production often reused in sandal manufacturing where small pieces are required than shoe. Small pieces are also used to produce leather goods (key ring).
Paper: thin paper disposals are often used as filler between insole and outsole. For this they are cut in to small pieces.
Synthetic materials: paper industries take charge of these disposals which includes different fabrics and fabrics materials, foam, threads, etc.
Cutting dice and sole moulds: These are made from aluminum alloy, so they are melting to reproduce those parts.
Last: damaged PU lasts can’t be used to produce new lasts as they result in low durability. So they used in production of other PU products.
PU sole: they are reused as soling material in injection moulded shoes.
TPR sole: these are cut into small granules and mixed with fresh granules in a ratio of 80:20 to produce TPR soles
Moreover, some companies sales their rejected shoes in comparatively low price
