Technology Series
The object of the technical memoranda in this series is to help to disseminate, among small-scale producers, extension officers and project evaluators, information on small-scale processing technologies that are appropriate to the socio-economic conditions of developing countries. Some publications in the series are described below.
ISSN 0252-2004
Tanning of hides and skins (Technology Series - Technical Memorandum No. 1)
Provides technical and economic information concerning the tanning of hides and skins at scales ranging from two hides per day (a typical rural tannery) to 200 hides per day. Six alternative tanning technologies are described, from a fully mechanised to a highly labour-intensive project. Subprocesses are described in great detail, with diagrams of pieces of equipment which may be manufactured locally. A list of equipment suppliers is also provided for those pieces of equipment which may need to be imported. This memorandum is, to some extent, complementary to that on the small-scale manufacture of footwear.

Small-scale manufacture of footwear (Technology Series - Technical Memorandum No. 2)
Covers the small-scale production of footwear (shoes and sandals) of differing types and quality, providing detailed technical and economic information covering four scales of production ranging from eight pairs per day to 1,000 pairs per day. A number of alternative technologies are described, including both equipment-intensive and labour-intensive production methods. Subprocesses are described in great detail, with diagrams of pieces of equipment which may be manufactured locally. A list of equipment suppliers is also provided for those pieces of equipment which may need to be imported.

Small-scale weaving (Technology Series - technical Memorandum No. 4)
Describes alternative weaving technologies for eight types of cloth (four plains and four twills) of particular interest for low- income groups in terms of both price and durability. The monograph provides information on available equipment (e.g. looms, pirning and warping equipment), including equipment productivity, quality of output, required quality of materials, and so on. A methodological framework for the evaluation of alternative weaving technologies at three scales of production allows the textile producer to identify the most suitable technology/scale of production. A chapter of interest to public planners compares, from a socio-economic viewpoint, the various weaving technologies described in the memorandum.

Small-scale brickmaking (Technology Series - Technical Memorandum No. 6)
Provides detailed technical information on different brickmaking techniques and covers all processing stages, including quarrying, clay preparation, moulding, drying, firing and the testing of produced bricks. The techniques described are mostly of interest to small-scale producers in both rural and urban areas. The processes and equipment are described in great detail, including drawings of equipment and tools which may be produced locally, floor plans, labour and skill requirements, materials and fuel inputs per unit of output. A list of equipment suppliers from both developing and developed countries is also supplied with a view to assisting the would-be brickmaker to import the required equipment. A chapter of interest to public planners compares, from a socio-economic point of view, the various brickmaking techniques described in this memorandum.

Small-scale paper-making (Technology Series - Technical Memorandum No. 8)
Provides technical and economic information on alternative paper-making technologies, describes the characteristics of various types and grades of paper products and gives guidance in the choice of paper machines. The information relates mostly to small-scale paper mills with a capacity of 30 tonnes of paper per day or less. The raw materials suggested for such mills include straw, bagasse, waste paper, rags and cotton waste, as well as other agricultural residues and imported wood pulp. Unlike other memoranda in the series, this memorandum is not a technical introduction to paper-making in general, nor is it a basic textbook on the subject. Instead, it provides people already in possession of the necessary back ground knowledge with criteria for choosing amongst different methods of paper-making.

Small-scale manufacture of stabilised soil blocks (Technology Series - Technical Memorandum No. 12)
Provides technical and economic information on alternative technologies for the production of stabilised soil blocks. The information relates mostly to small-scale units producing up to 400 blocks per day It covers all aspects of block making: the quarrying and testing of raw materials; the choice of soil stabilisers; pre-processing operations; block-forming methods, including a detailed description of machines currently available for making soil blocks; the curing and testing of produced blocks; and the use of mortars and renderings in wall construction. The first and last chapters evaluate the technical and economic efficiency of stabilised soil blocks in comparison with other building materials, and give some guide-lines for government action in support of the use of earth as a building material.
