One hundred andflfty years ago, carbohydrates from plant matter In all forms proulded the raw materlals for many lndustrlal products. By the 1970s. howeuer, the carbohydrate had been dlsplaced by hydrocarbons as the molecular bulldfng block of our Industrial economy. Now. technologlcal advances, enulronmental regulatlons. and green consumerism haue set the stage for the carbohydrate economy to ...

Preservatives used in both industrial and consumer products are well-known and important causes of contact allergy (1). The allergens relevant for this article are the preservatives methylchloroisothiazolinone (MCI) (CAS: 26172-55-4), methylisothiazolinone (MI) (CAS: 268220-4), and benzisothiazolinone (BIT) (CAS: 2634-335). MCI/MI (3:1) has been used as a preservative in cosmetics and household...

Industrial ecology is a new approach to the industrial design of products and processes and the implementation of sustainable manufacturing strategies. It is a concept in which an industrial system is viewed not in isolation from its surrounding systems but in concert with them. Industrial ecology seeks to optimize the total materials cycle from virgin material to finished material, to componen...

This paper proposes that industrial waste be regarded, in a business economic sense, as having the same basic status as regular products. A basic mathematical expression for assigning industrial costs to waste is presented. The expression can be employed in conjunction with cost-benefit analysis for estimating the “true” internal costs of industrial waste. In two case studies presented, industr...

The exchange of wastes, by-products, and energy among closely situated firms is one of the distinctive features of the applications of industrial ecological principles.This at= ticle examines the industrial district at Kalundborg, Denmark, often labeled as an “industrial ecosystem” or “industrial symbiosis” because ofthe many links among the firms.The forces that led to its evolution and to the...

Dairy products are colonized with three main classes of lactic acid bacteria (LAB): opportunistic bacteria, traditional starters, and industrial starters. Most of the population structure studies were previously performed with LAB species belonging to these three classes and give interesting knowledge about the population structure of LAB at the stage where they are already industrialized. Howe...

various industrial processes with a huge variety of products, materials and compounds create different kinds of pollution for human beings, so that the identification of environmental pollutants resulting from industrial units’ activities, especially in water resources seems necessary. the aim of this paper is to estimate the role of industrial units in contaminating water resources, through us...

Lead-rich solid industrial wastes were vitrified by the addition of glass formers in various concentrations, to produce non-toxic vitreous stabilized products that can be freely disposed or used as construction materials. Toxicity of both the as-received industrial solid waste and the stabilized products was determined using standard leaching test procedures. The chemically stable vitreous prod...
