Application: Heavy metals in industrial waste water
Today heavy metals in waste water are seen as one of the biggest problems of pollution. The attention of local governments to decrease the concentration of heavy metals in waste water is continuously increasing. The Problem: The online measurement of Industrial Waste Water introduces two technical problems to be solved. First, the complex waste water matrix will interfere with any accurate ...

Generation and management of industrial waste in Small and Medium sized Enterprises
This paper contains the results from the study and analysis of 100 Small and Medium sized Enterprises (SMEs) located in the Region of Castile and Leon (Spain), regarding generation, management, valorisation, treatment and final disposal of their waste. This study is an attempt to analyse the problems caused by industrial waste. To do so, an environmental survey was carried out on a random and ...

Leisure Industry Waste Management Case Study – Kudos in Brighton
The Brighton Centre is a world renowned Conference and Concert Venue and hosts high profile events such as Political Party Conferences, Indoor Sporting Events and large music concerts. GPT were asked to review the waste provision at the site following continual issues with service, poor recycling rates of less than 30% and a general lack of management information. A full site review was ...

Alkaline lipase production from Enterobacter aerogenes by solid-state fermentation of agro-industrial wastes
Lipases that are stable at alkaline pH are highly desirable for detergent formulations. In the present study, an alkaline lipase was produced from solid-state fermentation of agro-industrial wastes by lipase producer strain of Enterobacter aerogenes. Use of such wastes as substrates instead of commercial synthetic media was done to develop a cost-effective method for lipase production. ...

Modelling industrial waste management at regional scale
A mathematical model is proposed for planning a regional programme for industrial waste management. The model is based on economic optimisation and allows preliminary decisions to be made at the operational planning phase. Moreover, it allows management of the treatment and disposal of different types of industrial waste once the treatment facilities and the disposal sites are defined. The model ...

On sol-gel approach to geopolymerisation
Geopolymers have attracted much attention since the 1980s. However, their geopolymerisation mechanisms are not well understood, partly due to the complexity of the formation of amorphous phases that are difficult to characterise. The objectives of this paper are to first provide a-state-of-the-art review, and then to focus on the sol-gel chemistry of aluminosilicate which is able to describe the ...

A management framework for the implementation of policies for industrial ecology, Part II: a competitive bidding process
One strategy to implement Industrial Ecology (IE) is to utilise industrial waste streams as alternative sources of other needed materials. This paper is concerned with a competitive bidding process for converter selection to support the implementation of tax and subsidy policy that promotes secondary material converted from industrial waste, as a substitute for virgin material. With regard to the ...

Technological prospective study in the environmental industrial sector: management and treatment of industrial wastes
This paper shows the tendencies and future forecasts related to the impact that technological changes can have in the treatment and management of industrial wastes in the Castille and Leon area during the next ten years. We present here a summary of a technological prospective study carried out from November 1999 to November 2000, whose purpose was to predict, in the medium and the long term, the ...

Assessment of industrial by–product synergies from process engineering and sustainability principles
Industrial synergy has long been one of the applications of industrial ecology; popularised in the 1980's. Industrial synergy increases the interaction between industries through the utilisation of wastes/by–products, thereby offering a closed–loop system. A target application for industrial synergy is Primary industry which generates a huge amount of waste. Historically however, most existing ...

Waste Shredder for Sale in South Africa
AIShred double shaft shredder for sale in South Africa were designed for the fragmentation of pieces of large volume, resistance and thickness (such as plastic lees, coils, bales, wooden pallets, among others), leaving the material in a granulometry that allows grinding in a conventional knife mill, due to the two-axis cutting system, hexagonal and equipped with toothed flanges. This equipment is ...

Types of Industrial Waste Shredders
There are two main types of shredding systems to reduce waste materials. 1: Primary shredding Reduces materials down to 50mm up to 300mm. 2: Fines shredding Reduces materials to under 50mm per particle. Primary shredded waste can be further reduced by Fines shredding. Your outcome materials can then be cost effectively disposed of or sold for further use. Recycling shredder machinery is typically ...

Environmental management of industrial wastes in developing countries: Bangladesh Case Study
Industrial development in the developing countries of Asia, and in developing countries everywhere, has proceeded without control of pollution emissions and the resulting environmental degradation has now reached a serious level. The population problem, already severe, continues to get worse, forcing acceleration of urbanisation and industrialisation. An effective system for controlling ...

Application of current risk-based remediation criteria for the post-closure assessment of a former National Priorities List (NPL) site
Hurricane accelerated erosion and land loss of the Mississippi River coastal zone has necessitated a re evaluation of environmental risk at closed National Priority List (NPL) industrial waste sites in Louisiana, USA. Clean up criteria of a site were evaluated under the Louisiana Risk Evaluation Corrective Action Program (RECAP 2003). An assessment of the closed site using RECAP 2003 indicated ...

How to recuperate industrial waste heat beyond time and space
Any fossil fuel energy, after industrial utilisation such as combustion and electric generation, is finally emitted in the form of waste heat to the atmosphere. A database on waste heat revealed that a large amount of energy can be saved by reusing the high-temperature industrial waste heat efficiently. Thus, this paper introduces cutting-edge technologies for heat recovery by three promising ...

Evaluation of leaching characteristics and environmental compatibility of solidified/stabilized industrial waste
An attempt was made to judge the environmental compatibility, the governing leaching mechanism, and mobility patterns in a waste–cement solidified/stabilized matrix after 21 days of curing. The mixed sludge from a steel pickling facility was stabilized by ordinary Portland cement. Iron was the major leachable metal, along with Pb, Zn, and Mn. To characterize the leaching behavior, the mobility ...

A management framework for the implementation of policies for industrial ecology, Part I
This paper discusses the implementation of environmental policy, in particular tax and subsidy policy, that promotes secondary material converted from industrial waste as a substitute for virgin material. We describe a management framework for policy processes that effectively deals with uncertainties and risks arising from implementing the policy. The framework proposes a feedback strategy and ...

Utilisation of waste marble powder in cement industry
Presently large amounts of slurry are generated in marble cutting plants with serious consequences on the environment and humans. This paper presents test results showing the feasibility of using waste marble powder (WMP) in cement industry as a substitute limestone. Also, it describes the formulation of new lime–based (CR II) cementitious materials derived from these industrial wastes. The ...

Vacuum Evaporators for Industrial Waste Water Treatment
Industrial waste water evaporators are used to purify water by distillation, which is a process that involves heating the water to its boiling point and collecting the resulting steam, which is then cooled and condensed back into a liquid form. This process removes impurities and contaminants from the water, as they are left behind in the heating chamber. In this article by YASA ET we analyze ...
