Interest in the use of biomass for non-food applications has grown strongly in recent years, mainly as a consequence of its potential as a prime renewable energy resource. Renewable energies rank highly among the options that will contribute to the prevention of climate change and to security of energy supply in the future. Furthermore, exploiting biomass is very attractive as a way of dealing with two sensitive issues facing the majority of westernEuropean countries today; the extent of unemployment and the setting aside of farm lands to limit excess agricultural production.The 8th European Conference for Energy, Environment, Agriculture and Industry, held in Vienna, October 1994 was larger that any of its predecessors, with over 300 refereed contributions from 20 countries worldwide and over 520 participants. It was arguably the most significant event to date in this field, providing the opportunity for an international exchange of information on the recent progress in developing and implementing renewable biomass based non-food technologies. Published in 3 volumes, the proceedings of this conference therefore contain the most complete overview of the present state-of-the-art. Subjects covered include: biomass resource base, electricity and heat generation, transportation fuels, chemicals from biomass, products from bio- and thermochemical conversion technologies, economics, environmental aspects and opportunities for implementation worldwide, in particular in developing countries.Apart from the numerous contributions on the most recent results in research, development and implementation, the publication also contains authoritative reviews on most of the above-mentioned areas from leading experts in each field. In addition to this, it contains a list of key issues for developing a successful strategy leading to a rapid implementation in Europe and abroad.As a result it is indispensable for anyone working in this area, whether in research, demonstration or in policy development.

This workshop comprises part of the four-year (1985-1988) non-nuclear energy R & D programme for the development of renewable energy sources which is being implemented by the Commission of the European Communities. The aim of the workshop was to present work by the contracting laboratories in addition to work by numerous other research laboratories

This workshop comprises part of the four-year (1985-1988) non-nuclear energy R & D programme for the development of renewable energy sources which is being implemented by the Commission of the European Communities. The aim of the workshop was to present work by the contracting laboratories in addition to work by numerous other research laboratories in 11 European countries. Extensive discussions were also held on the present state of this basic, directed research in photochemistry, photoelectrochemistry and photobiology, and where the future emphasis may usefully lie.Thus the book presents the proceedings of all the papers presented and summarizes the recommendations made by the participants as to where future research support may be most effectively placed. It was emphasized in these recommendations that the interdisciplinary collaboration between photochemistry and photobiology had been quite successfully achieved in this European programme. There were both high quality basic research and practical benefits accruing from the work, and these are described in the report on proposed areas for future research.This book contains work reported by 30 leading researchers and laboratories in Europe. The contents parallels and overlaps research in photovoltaics and semiconductors and therefore provides a unique link and basis of information across the field of photovoltaics, semiconductors and photosynthesis.

Biomass pyrolysis has been practised for centuries in the manufacture of charcoal for industry and leisure. Only in the last two decades, however, has attention focussed on a better understanding of the science and technology, with the resultant benefits of better designed and controlled processes that give high yields of liquid products. These liquids, or 'bio-oil' as it is referred to, can be used in a variety of ways: -combustion to replace conventional fuel oil in boilers, process equipment such as kilns and in gas turbines for power generation; -upgrading by hydrotreating or with zeolites to gasoline, diesel and other hydrocarbon fuels, of chemicals; --extraction and upgrading to fuel additives and chemical specialities. Any charcoal produced can also be utilised to form char- water slurries, analogous to coal-water slurries, or bioi-oil slurries which may be used as liquid fuels in many combustion applications. A group of experts was set up in the EC Energy from Biomass programme to evaluate the status and opportunities for deriving useful liquid products from biomass pyrolysis. This book is a report of their findings and conclusions. It forms an authoritative guide to the wide range of technologies employed in biomass pyrolysis, and product upgrading, utilisation and characterisation. Recommendations and conclusions are included to identify promising areas of research and development that will be of value to researchers, planners and companies throughout the world.

This l:::ook comes as part of a new series on Solar Energy R+D, includlng Biomass which is carried out by the Euro:pean Community.. The commission of the European Comrmmities' Directorate General (XII) for Science, Research and Developnent is currently implementing, on a cost-sharing basis, a solar energy R+D pro;Jranune through contracts with European industry, research institutions and uni versi ties. This prcgrarrrrne includes a very strong acti vi ty on Biomass. Besides general R+D work on all aspects of Biomass growth and utilization which is reported elsewhere in this series, the Canmission is currently starting a new activity on Pilot Plants based on the use of Biomass for energy purp:Jses, and in particular on methanol prcx:luction from wood. The commission considers that the subject of methanol prcxiuction from wood offers llnp:Jrtant prospects for application wi thin the European Canmilllity and in other parts of the world, in particular some of the developing countries & The state of art in Europe In this field is still considered to be very high as a result of related work which was performed in Europe during ~vorld War II and the time before.

This paper is written in the belief that people are important and that equipment is to serve the needs of the people and therefore should be designed to meet their specific needs and environment. This is particularly important in the case of a developing country when a professional engineer accepts the responsibility to formulate policies evaluate equipment imple­ ment projects and train national people. 1. Government, geography and climate Papua New Guinea, an independent and self governing state since 1975, is located directly North of Australia above the North Eastern State of Queensland. The country extends from 141° east longitude, at the border with Indonesia (Irian Jaya) to 160° east longitude and between latitudes 1° and 12° south (see figure 1). Papua New Guinea is a parliamentary democracy, with a single legis­ lature known as the National Parliament (1). The State is divided into 19 provinces plus the National Capital District (Port Moresby) with de­ centralized Government established in each province. Before independence the country comprised the Australian territory of Papua in the southern regions and the United Nations Trust Territory of New Guinea in the North (1). Land area is 462,840 square kilometres This inclUdes the mainland, the three large islands of New Britain, ~ew Ireland and fiougainville plus 600 small islands and archipelagos. Approximate direct distances from the capital city of Port Moresby to some of the other centres are : Vanimo 990 km, Rabaul SOO km, Arawa 990 km and Lorengau S25 km.
