The purpose of this paper is to describe a project intended for the implementation of a formal cradle to grave management program for hauled or trucked industrial wastewater in Jordan.

Industries that do not have treatment onsite or that treat their industrial wastewater to a level not suitable for disposal into sewers or those that do not have access to sewer system have to haul their industrial wastewater to a treatment or disposal facility. At present most industries haul their industrial wastewater to a solid waste landfill site specially designated to receive industrial wastewater. In the program presented here, a manifest system for these industries have been introduced and implemented in a number of pilot projects.

A manifest form has been devised and used in a number of pilot demonstrations that enabled the formulation of specific conclusions and recommendations. Before implementing this manifest a program that includes training, awareness, governmental enforcement and commitment, and upgrading of disposal sites and laboratories capabilities has to be implemented.

Management of hauled industrial wastewater is very important in a water poor country like Jordan. The introduction of a manifest system and the identification of the problems associated with its implementation are key issues for sustainable development in Jordan.

A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

The purpose of this paper is to contribute original evidence about the conditions for formal and informal contracts for commodities and labour in the waste economy of a South Indian town.

Field research was exploratory, based on snowball sampling and urban traversing. The analysis follows capital and labour in the sub-circuits of capital generating waste in production, distribution, consumption, the production of labour and the reproduction of society.

Regardless of legal regulation, which is selectively enforced, formal contracts are limited to active inspection regimes; direct transactions with or within the state; and long-distance transactions. Formal labour contracts are least incomplete for state employment, and for relatively scarce skilled labour in the private sector.

The research design does not permit quantified generalisations.

Waste management technology evaluations neglect the social costs of displacing a large informal labour force.

While slowly dissolving occupational barriers of untouchability, the waste economy is a low-status labour absorber of last resort, exit from which is extremely difficult.

The first systematic exploration of formal and informal contracts in an Indian small-town waste economy.

SMT stencil cleaning has traditionally been thought of as a ‘maintenance’ procedure with little or no impact on production. Today, CFC and VOC cleaning processes are being replaced because of environmental concerns, and fine‐pitch and ultra fine‐pitch assemblies are commonplace. These changes in cleaning processes and product specifications have shed new light on the importance of properly cleaning SMT screens and stencils in order to prevent damage to the stencil and potential production‐related problems.This paper takes an unbiased look at the different stencil cleaning processes available through the eyes of an SMT stencil manufacturer. The paper outlines the advantages and disadvantages of using ‘jet spray’ washersvs ‘ultrasonic’ washers, aqueous and semi‐aqueous vssolvent cleaning agents, and the effects of hot wash solutions and hot drying air vsambient wash solutions and drying techniques.Specific criteria evaluated include: cleaning effectiveness of the process; potential adverse effects of the process on the integrity of the stencil; production down‐time and other potential production‐related problems; potential health hazards to users; environmental impact of the process, and waste stream management.Magnified photography is used to demonstrate the relative effectiveness of various cleaning technologies. Third party references of other industry experts, along with the author's own experiences, are cited to support the information provided.

The British countryman is a well‐known figure; his rugged, obstinate nature, unyielding and tough; his part in the development of the nation, its history, not confined to the valley meadows and pastures and uplands, but nobly played in battles and campaigns of long ago. His “better half”—a term as true of yeoman stock as of any other—is less well known. She is as important a part of country life as her spouse; in some fields, her contribution has been even greater. He may grow the food, but she is the provider of meals, dishes, specialties, the innovating genius to whom most if not all British food products, mostly with regional names and now well‐placed in the advertising armentarium of massive food manufacturers, are due. A few of them are centuries old. Nor does she lack the business acumen of her man; hens, ducks, geese, their eggs, cut flowers, the produce of the kitchen garden, she may do a brisk trade in these at the gate or back door. The recent astronomical price of potatoes brought her a handsome bonus. If the basic needs of the French national dietary are due to the genius of the chef de cuisine, much of the British diet is due to that of the countrywoman.

The purpose of this paper is to highlight the relationship between lifestyles, household and household wastes, by exploring possible future development path for the lifestyle and the possible consequences for household waste composition. The study predicates on a reasonably simple and straightforward idea that the waste generated from homes is a product of the way the people live and since the way of life of people change overtime, getting an idea of how people may live in future may give an insight into the sorts of composition of waste produced by them. It tends to provide a contribution to the evidence base on household waste at a general level.

The overall approach hinged on the notion that the household is the appropriate analytical unit of household waste production composition. This specified inputs needed to develop scenarios for future waste composition. The weekly generation of sorted wastes from their various sources was determined by direct measurement in kilograms on a weighing scale. Questionnaires were administered to elicit information on key drivers and factors that influence lifestyles scenarios and their development. Interviews were conducted with relevant stakeholders and government agencies on waste management.

The results indicated that food related waste constituted the major percentages and tonnages (44 percent, 269,870 tons) of household waste, while the least portion was glass (1.2 percent,7,278 tons). The key drivers responsible for generation of food waste include level of income, subsistence farming that generate organic food waste and rise in fast food outfits that give preference to readymade food over cooking at homes. The drivers for developing future scenarios include population, government regulations, nature of apartment, level of income, consumer spending, management technology. Three scenarios were developed: status quo trends, strong government and destination point.

Models should be developed for better simulation studies of lifestyle scenarios by quantifying household wastes in terms of carbon footprint and money instead of relying on quantities generated in tons. Further studies should extend to other sources of waste such as industrial waste, electrical and electronic waste, among others. The implication from research findings shows the need for sustained for sustained awareness on people’s lifestyle with regard to handling of household wastes by government agencies, institutions and non-governmental organizations. Scenario planning is required to enable, encourage and engage householders to make changes in their lifestyles.

Food waste, by virtue of its tonnage and percentage composition, dominated the overall picture during the study period and will continue to do so in the near future. The composition of household waste in the future will be driven by the population and lifestyles of the householders. The drivers of lifestyles are crucial factors that determine the picture of the future. Furthermore, it is possible to conjecture circumstances in which household waste is converted to wealth at the destination point but the period before then imply some radical changes in both lifestyles and underlying economic growth facilitated by a strong political will.

This research could be of enormous benefit to policy makers, practitioners and others with an interest in or responsibility to the development and implementation of sustainable waste management. Scenarios are devices for enabling organizations and the individuals within them better to understand their operating environment, so as to make better decisions. This research is a scenario-planning exercise, considering how future changes in lifestyles of people in Port Harcourt metropolis now and in future may impact on the future composition of wastes they generate.

Fumes, grit, dust, dirt—all have long been recognized as occupational hazards, their seriousness depending on their nature and how they assail the human body, by ingestion, absorption, inhalation, the last being considered the most likely to cause permanent damage. It would not be an exaggeration to state that National Insurance (Industrial Injuries) provisions, now contained in the Social Security Act, 1975, with all the regulations made to implement the law, had their birth in compensating victims of lung disease from inhalation of dust. Over the years, the range of recognized dust disease, prescribed under regulations, has grown, but there are other recognized risks to human life and health from dusts of various kinds, produced not from the manufacturing, mining and quarrying, &c. industries; but from a number of areas where it can contaminate and constitute a hazard to vulnerable products and persons. An early intervention by legislation concerned exposed foods, e.g. uncovered meat on open shop fronts, to dust and in narrow streets, mud splashed from road surfaces. The composition of dust varies with its sources—external, atmospheric, seasonal or interior sources, uses and occupations, comings and goings, and in particular, the standards of cleaning and, where necessary, precautions to prevent dust accumulation. One area for long under constant scrutiny and a subject of considerable research is the interior of hospital wards, treatment rooms and operating theatres.

The distribution sector has been hard hit by the energy/ecology crisis. Higher fuel costs coupled with reduced availability of many energy sources have adversely affected distribution activities. Growing levels of pollution have caused global concern. As a part of the physical distribution activity, the transportation modes have been particularly vulnerable to the energy/ecology crisis because they rely so heavily on energy resources. It is important that those involved in physical distribution understand the distribution‐energy/ecology interface. Recognition of the effects that the energy/ecology crisis has had, and will have, on distribution is an integral part of logistics planning and control. The energy/ecology crisis will not go away and it behoves the physical distribution manager, educator and public policy maker to: (1) Understand the Problem, (2) Recognise how the problem pertains to him directly and/or indirectly, and (3) Determine how he and others will react to the problem in the future.

In this chapter we explore some of the intriguing questions raised by contaminated communities. Is there a connection between exposure to environmental hazards and psychological distress? If yes, how best can it be measured? What kinds of psychological problems are aggravated by this kind of life stress? How do we know that victims are truly experiencing increased problems such as anxiety, depression and fears about their health?

Local landfills in communities across the US are the battlegrounds in the conflict between our desire to consume goods at an extraordinary rate and our inability to deal with waste that is a by-product of this consumption. Despite efforts to reduce the amount of wastes generated through source reduction, in 2003, US residences, businesses, and institutions produced more than 236 million tons of municipal solid waste (trash and garbage), approximately 4.5 pounds of waste per person per day (EPA, 2003a). Also in 2003, 16,694 generators of regulated hazardous waste accounted for more than 30 million tons of hazardous wastes, more than half a pound of hazardous wastes per person per day (EPA, 2003b).
