Lateral Thinking

Most current discussion on the techniques for effluent control emphasise the sophisticated approach most appropriate to advanced industrial operations in prosperous environments. This paper aims to demonstrate that a more basic approach still has a valuable role to play. A series of case studies from the United Kingdom examine how the application of simple techniques were able to provide significant environmental benefits at minimal net cost to the discharger. The examples ranged from raw materials recovery and waste recycling, to lateral thinking and the development of non polluting processes. The consequent reductions in effluent load to receiving waters have been found to be highly significant for the environment.

Purpose Isolated communities face a variety of inconveniences including severe remoteness, poor roads and extreme climate conditions, resulting in the lack of security of supply chains and exorbitant prices for cargo delivery. This paper aims to investigate the present advantages and prospects of applying 3-D printing to improve economics and everyday life of remote communities, reindeer herder case taken as an example. Design/methodology/approach This study covers the use of a low-cost open-source 3-D printer (RepRap) capable of fused filament fabrication to reduce operating costs for nomadic reindeer herder groups. Three case studies are provided for reindeer-specific applications to probe economic and technical viability of the technology, namely, ear-tags, electric fence components and lasso accessories. Findings 3-D printed objects feature technical characteristics similar to those of analogues available on the market while reducing the price by 63 per cent. Distributed 3-D printing reduces the cost of raw materials by 68 per cent and shipping costs by 50 because of lower trip frequency. If all reindeer herders globally were to adopt distributed manufacturing of the three aforementioned sample items only, their annual savings from such solution would amount to US$2m. The paper discovers other economic, entrepreneurial, technical and environmental opportunities offered by 3-D printing put to service the needs of remote communities. Research limitations As the paper is the first-ever study of 3-D printing potential applied to the reindeer husbandry case, it is based on a more thorough analysis of the techno-economic feasibility of the technology, while cultural and entrepreneurial factors have been discussed as preconditions only. Practical implications The paper might serve as a valuable source of information for entrepreneurs, as well as for students and academics for further case studies in this area. Originality/value In remote conditions, 3-D printing offers a more sustainable way of good manufacturing. Numerous open source designs already available for specialists, financial effectiveness, environmental benefits and vast opportunities for entrepreneurs are among the most promising advantages of the technology.

Recycling Systems

Industrial ecology (IE) is a biological concept applied to industrial structures. The basic concepts of IE include regional, intra-firm and product-based waste recycling systems as well as the principle of upward and downward cascading. In best current examples of regional systems, several parties are in an industrial waste re-use symbiosis. Paper industry has learned to arrange the recovery and re-use of its products on distant markets, even up to a level where indications of exceeding optimal recovery and re-use rates already exist through deteriorated fibre and product quality. Such occurrences will take place in certain legislative-economic situations. Paper industry has many cascade levels, each with their internal recovery and recycling, as well as many intra-firm, regional, and life cycle ecology structures. As an example of prospects for individual cascading routes, sludges may continue to be incinerated, but the route to landfills will be closed. The main obstacles of legislative drive toward better IE systems are in many cases existing laws and political considerations rather than economic or technical aspects. The study and practice of engineering human technology systems and related elements of natural systems should develop in such a way that they provide quality of life by actively managing the dynamics of relevant systems to reduce the risk and scale of undesirable behavior and outcomes. For the paper industry, earth systems engineering offers several development routes. One of them is the further recognition of and research on the fact that the products of the industry are returned back to the carbon cycle of the natural environment. Opportunities for modifying current earth systems may also be available for the industry, e.g. genetically modified plants for raw materials or organisms for making good quality pulp out of current raw materials. It is to be recognized that earth systems engineering may become a very controversial area, and that very diverse political pressures may determine its future usefulness to the paper industry.

Critical Raw Materials

Major benefits and constraints related to mineral extraction within the EU have been identified on the examples of selected critical raw materials’ deposits. Analyzed case studies include the following ore deposits: Myszków Mo-W-Cu (Poland), Juomasuo Au-Co (Finland), S. Pedro das Águias W-Sn (Portugal), Penouta Nb-Ta-Sn (Spain), Norra Kärr REEs (Sweden) and Trælen graphite (Norway). They represent different stages of development, from the early/grassroot exploration stage, through advanced exploration and active mining, up to reopening of abandoned mines, and refer to different problems and constraints related to the possibility of exploitation commencement. The multi-criteria analysis of the cases has included geological and economic factors as well as environmental, land use, social acceptance and infrastructure factors. These factors, in terms of cost and benefit analysis, have been considered at three levels: local, country and EU levels. The analyzed cases indicated the major obstacles that occur in different stages of deposit development and need to be overcome in order to enable a new deposit exploitation commencement. These are environmental (Juomasuo and Myszków), spatial (Juomasuo) as well as social constraints (Norra Kärr, Juomasuo). In the analyzed cases, the most important constraints related to future deposit extraction occur primarily at a local level, while some important benefits are identified mainly at the country and the EU levels. These major benefits are related to securing long-term supplies for the national industries and strategically important EU industry sectors.

The Impact

Animal experimentation has been subject to legislative control in the United Kingdom since 1876. This paper reviews the impact of that legislation, which was replaced in 1986, on the teaching of practical physiology to undergraduate students. Highlights and case studies are also presented, drawing on Government reports and statistics, published books and papers, and unpublished archival data.

The purpose of the article. The purpose of the study is to substantiate the theoretical foundations and practical innovative solutions for the reuse of waste resources with a proposal for improved waste management technology with prospects for implementation in Ukraine. Research methodology: theoretical and practical aspects of the introduction and implementation of eco-management, because for Ukraine such an approach to the introduction of innovative processing technologies in enterprises is completely new. Methodical toolkit of substantiation of innovative decisions of reuse of resources from waste, structure of prime cost of the improved system for the Goloseevsky area. Kiev. Scientific novelty. It is proposed to optimize the existing garbage problem in most regions and replace waste trucks based on the method of the pneumatic system manufactured by Envac. The system allows you to reduce the cost of moving cargo over time sorting or disposal points. Conclusions. The introduction of innovative systems in Ukraine for the year saves UAH 34 billion 499 million, in addition, the sorting of household waste is gaining popularity, recycling tanks are being installed in cities, the population is beginning to treat waste with understanding, and a behavioral strategy has been introduced to stimulate waste recycling. In addition, the proposed technology of sorting raw materials allows you to sort up to 97% of household waste, and the rest to burn for energy. All this makes the development of the processing industry in Ukraine promising. Keywords: innovations, waste-free systems, secondary raw materials, energy, technology.
