Environmentally friendly products

With the renewed interest in environmentally friendly products, ceUulose esters are being re-evaluated as a natural source of biodegradable thermoplastics. CeUulose acetates are potentiaUy biodegradable (152). Films prepared from a ceUulose acetate with a DS of 2.5 were shown to require only a 10—12 day incubation period for extensive degradation in an in vitro enrichment assay. Similarly, films prepared from a ceUulose acetate with a DS of 1.7 saw 70% degradation in 27 days in a wastewater treatment facUity, whereas films prepared from a ceUulose acetate with a DS of 2.5 required approximately 10 weeks for similar degradation to occur. The results of this work demonstrate that ceUulose acetate fibers and films are potentiaUy environmentally nonpersistant. 

Lacl<. of markets. The implementation of pollution-prevention processes and the production of environmentally friendly products will be of no avail if markets do not exist for such goods. As an example, the recychng of newspaper in the United States has resulted in an overabundance of waste paper without markets prepared to take advantage of this raw material. 

Corporate environmentalism is an evolving concept for environmental protection. In this case, business takes a pro-active stance independent of regulatory authorities. This can be in recognition of social responsibilities, but is more successful when compelled by competition in the market place. Thus, a hrm can conscientiously target environmentally aware consumers (through marketing environmentally friendly products or processes) or can be better placed for hnancial support from ethical investment funding bodies. 

In the following we shall examine a model system for the car catalyst where CO and NO react to yield the more environmentally friendly products CO2 and N2. The reaction shall be split up into the following elementary steps, which all are assumed to be in quasi-equilibrium, except step 2, which is assumed to be the rate-limiting step ... 

Durability. Durability can be a useful way of improving eco-efiiciency. A product that has a long useful life minimises the impact per unit of service in the overall life cycle. However, there needs to be a balance, as a durable product with a poor environmental performance may block the introduction of a more eco-efficient technology. In many cases, governments have been driven to use fiscal incentives to encourage the adoption of a more environmentally friendly product because of the installed base of older but durable technologies. 

The further development of organic agriculture thus depends not only on animal friendly and environmentally friendly production methods, but also...

With a new generation of flexible adhesives/sealants on an MS polymer base, the firm of Henkel Teroson inHeidelbeig is offering yet more application possibilities. The Terostat MS family of environmentally friendly products stands out above all for its expansion into yet greater toughness. Traction toughness has been increased up to 2.5 Mpa (DIN... 

Choose esterquats over DHTDMAC for environmentally friendly products, since they biodegrade more rapidly and are less toxic to aquatic life. 

Consider using naturally extracted solvents like pine oil and d-limonene for environmentally friendly products. 

In concepts for new products the performance, product safety, and product economy criteria are equally important. They are taken into account already when the raw material base for a new industrial product development is defined. Here, renewable resources have often been shown to have advantages compared with fossil feedstock. Over the years it has been demonstrated that the use of vegetable fats and oils in oleochemistry allows the development of competitive, powerful products that are both consumer- and environmentally-friendly. Products from recent developments fit with this requirement profile. 

The key problem with buying lumber for use in the yard is that so much of it—posts for outdoor use, fence panels, and compost bins, for example—is routinely treated with some sort of preservative before sale. Organic gardeners should, if possible, avoid treated lumber and products, unless a relatively environmentally friendly product has been used.

Environmentally friendly production of hydrogen from Norwegian natural gas. 

Application of metabolic engineering techniques can obviously result in higher yields and productivity, but also fewer side-products and improved stereospecificity. In contrast with competing chemical processes environmentally friendly production methods and renewable resources can often be used for production of high-value products. 

For many years the need to have environmentally friendly products and processes was seen by many chemical companies as a necessary, but additional, cost to be borne by the business. Whilst there is still a cost, it is now more often seen as beneficial to the business and indeed to offer financial opportunities, if the challenge is accepted in an innovative fashion.

Wei Mon Industry Co. was established in 1987 to manufacturing concrete piping materials as well as contracting major civil infrastructure projects such as water supply pipelines, sewerage systems, and land developments. Since 1996, Wei Mon started to research and develop natural and environmentally-friendly products, including Biodegradable Plastic Products.
