Solvants écologiquesIndex. décimale : 660 Technologie chimique (chimie industrielle) et techniques connexes Résumé : The uses of hazardous and toxic solvents in paint laboratories and in paint industries are considered a very crucial problem for health and safety of workers and environment. Majority of solvents are organic chemicals with harmful and toxic properties, large waste part of by-products of the chemical industry causing environmental and health problems, but its uses are important. So, it is better to prevent voc and minimize waste than to face problems and treat or clean up waste after it has been created, therefore, it is widely acknowledged that there is a growing need for more environmentally acceptable processes in the chemical industry.
The trend towards what has become known as Green Chemistry' or Sustainable Technology', necessitates a paradigm shift from traditional concepts of process efficiency, that focus largely on chemical yield, that assigns economic value to eliminating waste at source and avoiding the use of toxic and/or hazardous substances.
The review paper is mainly based on the Green chemistry, which places both company profitability and ecological health at the heart of innovative product design and manufacturing. It uses the creativity of nature's biological processes to create molecules, materials and processes that are safe and high-performing.Note de contenu : - SUSTAINABLE GREEN CHEMISTRY : Economic - Materials - Waste

Produits et matériaux recyclésIndex. décimale : 668.5 Parfums et cosmétiques Résumé : We explains how it develops ingredients sourced from upcycled processes with a wide variety of benefits for people and planet.
Upcycled ingredients are catching on as a go-to solution for brands focused on delivering more responsible beauty. The notion of reusing waste or discarded by-products from cosmeticdestined plants or food production to create higher value, high-quality new personal care ingredients, is exciting and significant for those looking closely at their formulations to improve sustainability. Particularly when sourcing and efficacy have been prioritized within their development, such ingredients can tick multiple boxes occupying the industry and its consumers.
Nowadays, there is a need to keep pace with reducing environmental impact, providing greater transparency, and the emerging push for circular beauty practices when creating appealing, effective products that fit the wellestablished preference for milder skin care and scalp care. Here, upcycled ingredients are an attractive option for formulations, as sustainable functional raw materials that perform well and contribute to zero waste cosmetics and the circular economy.
Their use can support brands in pursuing the Sustainable Development Goal of responsible consumption and production (SDG 17). Meanwhile, consumers can follow their desires for a deeper, more respectful connection with nature through the products they choose and the brands they support.Note de contenu : - Clariant’s approach up-close

Tannage au chromeIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In a recent article Smith notes that emphasis on environment, health, and energy conservation has led to new studies to increase the efficiency of chromium usage in a tannery. He cites four basic concepts for increasing efficiency, these being improved uptake, recycling chrome liquors, precipitation and recovery of chrome for reuse and alkaline incineration. Utilising various techniques, all of the first three are practical commercially, while the fourth is being studied seriously from both chrome recovery and solid waste disposal perspectives. Since the first disclosure of a practical chrome tanning process in 1858 there have been literally hundreds of publications about the chemistry and technology of chrome tanning. It is estimated that about half relate to improved chrome uptake, but they can be classified into four main categories. These are control of pH, selection of masking agents, control of time and temperature, and control of float (or concentration).
pH control does not necessarily mean increasing the pH at the end of chrome tanning by adding more neutralising agent. It does include employing more modern techniques such as adding magnesium oxide, a sparingly soluble basifying agent, for control of neutralisation ; or a combination of conventional and self-basifying chrome ; or even a chelated chrome added immediately following the bate. Selection of masking agents can be very critical. The more conventional formate and acetate masking can lead to more rapid arome penetration, while the more complex, polybasic acids which affect the size of the chrome complex can decrease penetration but improve fixation. Time, temperature and control of float are all rational and interrelated. Since chrome tanning is both a physical (diffusion) and a chemical (reaction) process which ultimately leads to an equilibrium situation, any condition which achieves equilibrium more rapidly or at equilibrium increases the quantity of total fixed chrome relative to the total unfixed chrome will improve uptake. The conditions are, of course, low float, higher temperature and longer running times.
It is now possible to add a fifth category to the techniques for improved chrome uptake. Although currently there is insufficient evidence to establish the mechanism of action, it is apparent that a class of chemicals has been discovered, broadly defined as amine salts, which shifts the equilibrium of chrome between stock and float such that more chrome is exhausted in the stock and less remains in the exhaust liquor. This paper describes the results of our laboratory programme to determine the effect of process variations and define an optimum process for tannery trials. The results of confirmatory tannery trials are also reported.Note de contenu : - EXPERIMENTAL : Tanning process - Measurements
