1. The Committee was informed that the manufacture of shredded suet from imported premier jus is subject to control by licence and that it is a condition of the licences that the product shall contain not less than 83 per cent. of fat. This figure was adopted in 1931 by the Council of the Society of Public Analysts and Other Analytical Chemists pending the establishment of a legal standard. 2. In the manufacture of shredded suet premier jus the fat is forced into shreds or granules and a cereal or amylaceous filler is added so as to form a coating over the particles of fat, thus preventing them from adhering together and at the same time retarding the development of rancidity. 3. The amount of filler taken up by the shredded fat depends primarily on its stickiness, which in turn depends on the temperature at which the manufacturing process is conducted. Manufacturers must give special attention to the problem of securing uniformity of distribution, otherwise part of a batch will take up more than its share of the amount of filler allowed by the manufacturing formula. In spite of all practicable care, complete uniformity cannot be ensured and some tolerance is therefore necessary to allow for unavoidable variations. 4. The proportion of filler used in the past by different manufacturers has varied considerably. A purchaser of shredded suet is primarily purchasing fat and it is desirable that the fat content shall be the maximum that can be included whilst still retaining good keeping properties. The Committee is of the opinion that shredded suet, to be of satisfactory quality, should not contain substantially less than 85 percent. of fat, and that a product approximating to this standard will have the necessary keeping properties. The Committee is satisfied that the allowance of 2 per cent. for uneven distribution on and among the shreds, which was adopted by the Council of the Society of Public Analysts in 1931, is reasonable, and understands that it is considered adequate by the manufacturers of shredded suet. 5. A small amount of suet (i.e., natural unrendered fat), received by butchers as part of their meat allocation, is chopped or minced, and in the latter case mixed with cereal filler and sold under the description “shredded suet.” By whichever method it is prepared it differs from the shredded suet made from premier jus by reason of the presence of membrane and moisture. If made by chopping it will contain more fat than the product made from premier jus, but if made by mincing and admixture with a filler it is likely to contain less owing to the membrane and moisture in the raw material and the impracticability of analytical control. 6. It was suggested to the Committee that the use of the description shredded suet for the products made by butchers was misleading and that the name should be restricted to the product made from premier jus. The Committee is, however, of the opinion that the general public would be equally satisfied whether the product supplied in response to a demand for shredded suet had been prepared with premier jus or suet. Further, it is considered that a purchaser of shredded suet is not prejudiced if he receives a product containing membrane and moisture provided he also receives the appropriate amount of fat. It therefore does not appear to the Committee that there is any necessity, from the viewpoint of protecting the public in regard to quality, for recommending the imposition of this restriction. 7. The Committee noted that the statement issued by the Council of the Society of Public Analysts included an expression of opinion that “the nature of any admixture to suet should be declared.” This recommendation is, however, outside the terms of reference of the Committee and no comment is therefore made thereon. 8. The Committee accordingly recommends that shredded suet should be required to contain not less than 83 per cent. of fat.

Nowadays millions of pounds can be spent in research, development and marketing of a new food product. Over ninety years ago, an American lawyer invented a brand new food which has changed very little over the years and is still extremely popular. Every eight hour shift, one million Shredded Wheat are produced, and two of them make a very good breakfast for one person.

The Departmental Committee appointed in June, 1924, to inquire into the question as to whether and to what extent the practice of treating flour with chemical substances is objectionable on grounds of health and whether it is desirable that the practice should be prohibited or restricted, have issued their report. The Committee observe :—

Paper recycling is an environment friendly technology used worldwide. The process involves turning waste paper into new paper products. According to the Society for Technology and Action for Rural Advancement (TARA), the process includes shredding of waste paper, soaking the shredded paper in water overnight, feeding the shredded soaked paper inside the hydrapulper, transforming wet material into pulp, forming pulp into required and specified size of paper, squeezing out excess water from wet paper, drying the wet sheet on cloth, removing the paper from the cloth, cutting paper into definite size, and finally manufacturing the product. Handmade paper can be used for making different paper products. This simple technology can reduce environment degradation, produce cost-effective paper, inculcate skill development, and create livelihoods. This chapter highlights a specific activity initiated in 2007 by the author in the capacity of then director, UGC Centre for Women Studies, BITS, Pilani. The activity involved setting up the TARA Mini Paper Recycling Unit, sponsored by the UGC Centre for Women Studies, BITS, Pilani, training 10 rural women on the process of making paper from waste paper and making end products out of recycled paper. The outcome of this activity was economic empowerment and helping women acquire skills of making paper from waste paper.

The purpose of this study was to improve the overall equipment effectiveness (OEE) of the production process of the shredder operation of ABC company, an industrial waste management company which supplies pre-processed industrial waste as alternative fuel to a cement plant.

This case study investigated all possible availability and performance losses that caused the shredder system’s OEE and various problem-solving techniques, such as root cause analysis and Pareto analysis, were used to find the root cause of the reduced OEE.

After analysing this case study, three significant loss factors were identified from all the availability and performance losses, which caused the shredder system’s OEE losses. Practical solutions were found for the effect of those loss factors to improve the machine’s OEE and productivity.

This case study has been concentrated on only analysing of losses and improvement of OEE in the production process and not about cost analysis between loss and improvements.

This paper shows how to improve the OEE of a production process through various problem-solving techniques by identifying its losses and how to achieve the best solutions for those losses in a practical manner.

A low‐cost, open source, self‐replicating rapid prototyper (RepRap) has been developed, which greatly expands the potential user base of rapid prototypers. The operating cost of the RepRap can be further reduced using waste polymers as feedstock. Centralized recycling of polymers is often uneconomic and energy intensive due to transportation embodied energy. The purpose of this paper is to provide a proof of concept for high‐value recycling of waste polymers at distributed creation sites.

Previous designs of waste plastic extruders (also known as RecycleBots) were evaluated using a weighted evaluation matrix. An updated design was completed and the description and analysis of the design is presented including component summary, testing procedures, a basic life cycle analysis and extrusion results. The filament was tested for consistency of density and diameter while quantifying electricity consumption.

Filament was successfully extruded at an average rate of 90 mm/min and used to print parts. The filament averaged 2.805 mm diameter with 87 per cent of samples between 2.540 mm and 3.081 mm. The average mass was 0.564 g/100 mm length. Energy use was 0.06 kWh/m.

The success of the RecycleBot further reduces RepRap operating costs, which enables distributed in‐home, value added, plastic recycling. This has implications for municipal waste management programs, as in‐home recycling could reduce cost and greenhouse gas emissions associated with waste collection and transportation, as well as the environmental impact of manufacturing custom plastic parts.

This paper reports on the first technical evaluation of a feedstock filament for the RepRap from waste plastic material made in a distributed recycling device.

Those local authorities in this country who have been carrying out extensive training courses for food handlers must, at this time of the year with annual estimates fresh in their minds, together with frequent exhortations for economy, give much thought to the ultimate results of their efforts. In order to proceed further with this analysis, it is necessary to divide the authorities into three main groups: (1) those that have had a comprehensive system embracing lectures to all types of food handlers in hotels, food shops, fishmongers, bakers and greengrocers, etc.; (2) those who are content with one or two public lectures, or those whose campaigns take the form of a Clean Food Week; and finally (3) those who have no organised training programme, do not intend to have one and rely entirely on visits by Health Officers to advise and enforce the necessary Acts and local bye‐laws. It is imperative that a system of regular and thorough inspection of these premises be carried out at least once every three months, irrespective of what type of auxiliary training and lectures are put into force. Those officers who have spent a great deal of time in taking these courses and lecturing have found that there are many people who will not ask questions in front of an audience and to these advice during inspection is of the utmost importance. Particular difficulties in relation to equipment and layout can often be solved on the premises which would not be possible at a lecture even if the food handler would put his questions forward at that time. In order to check improvements, division into the three groups above will assist in assessing the achievements in any training programme. The consensus of opinion among health authorities in this country shows that comprehensive training programmes do pay good dividends. Later inspections show that there are improved conditions in food shops and improved working relations between the food industry and the local health department and, most important of all, increased public interest in, and support for, the cleaner food ideal. This assessment has also been borne out by the experience of authorities in the United States of America. In one large city in Columbia, 70 per cent of the staff of the licensed restaurants had completed training courses and one was interested to learn that in the “ A” restaurants the Health Department had issued tabs to be attached to menus which read: “ Our dishes and utensils are sanitised; our employees are trained; our kitchen invites your inspection”. Of particular interest in this respect is the attention paid to catering at fairs, a very thorny problem in this country. The Missouri Division of Health have stated that, during the past four years, there has not been a single reported case of food poisoning and that this has been accomplished, not only by means of regulations, but with constant supervision and a mobile laboratory that follows the fairs. It also stresses the value of dispensable paper cups and dishes that obviate the necessity for washing and sterilising facilities, often most difficult to obtain with mobile fairs and peripatetic catering. In one county in Kansas courses are planned by the Public Health Department and the Adult Education Sections of the Schools. All food handlers are required to have a card saying that they have successfully completed the course and this card is valid for one year only and personnel must complete a refresher course before obtaining a new card. The rates of improvement vary considerably but in all authorities in the United States of America, where comprehensive programmes have been carried out over a few years, definite improvement has been found in food handling. This is not the only aspect that must be considered at the present time. The potentiality of highly trained staff is of the utmost value in case of emergency. This was demonstrated in the very serious flooding that occurred in Kansas inundating hundreds of houses and disorganising public services. This problem arose at very short notice and the fact stressed by the State Board of Health was that, although the crisis lasted from a period of weeks to several months, not a single case of disease was traced to water supplies or to food. These emergency measures are undoubtedly the most stringent test of public health organisation and of the efficiency of those who handle and distribute food. In such cases, there is never sufficient time to start any scheme of training, but, with skilled staff, the spate of illnesses, such as typhoid, dysentery, etc., that invariably accompanied such occurrences could be reduced, if not eliminated, where efficient schemes of training have been carried out. When assessing the value of food training courses in such an emergency, one is forced by present conditions to think again of how it will fit in with Civil Defence requirements. The experience of the last war showed that the task of feeding large numbers of evacuees is a tremendous problem. It is not sufficient merely to have stores of food at strategic points, but trained people must be available who can not only make the most use of the food, but will know how to reduce the incidence of food poisoning or transference of infection when dealing with communal feeding of this type. To the foregoing must be added the risk that power and fuel might be cut off and also other main services. Then washing and sterilisation of equipment would not be possible. Experienced workers in this sphere will, prior to such conditions, have plans in hand that will cover all these contingencies. It may be necessary to feed homeless exacuees, Civil Defence workers operating in devastated areas, and even distribute food for the remaining citizens in towns where normal services have ceased to exist. It is in these circumstances that the food handler who has had thorough training will be able to carry on, well knowing the risks and taking every precaution to avoid the spread of infection and consequent epidemics.

Using the Bennett (1991) and Berle (1991) publications as a historical picture of what were considered to be “best-practice” examples of ecopreneurial businesses in the 1990s allows a longitudinal assessment of the success and failure of such businesses almost two decades on. Tracking their evolution facilitates the consideration of emerging patterns in their development, such as what happened within certain industries, whether common patterns emerge in the role of the founder ecopreneurs and how successful different firms actually were.
