Transcript of Green Chemicals

Chemistry 1. Prevent Create products without or with minimal wastes so that the wastes do not need to be taken care of afterwards. Design chemicals to have little or no toxicity, without affecting effectiveness. 2. Design 3. Design Design a way of synthesising products without it being toxic to humans or the environment. 5. Catalyst Use of catalysts because of their ability to be able to be reused and that they are less harmful than reagents. 6. Avoid Chemical derivatives generate wastes that can be avoided. 7. Maximise Make sure that a greater percentage of the atoms present in the reactants of a chemical reaction are used in the products that are also usable. 8. Use Avoid using harsh solvents, but if that cannot be avoided, then use benign chemicals. 9. Increase Use the normal ambient temperature and pressure wherever possible. 10. Design Design materials to breakdown into benign substances by bacterial or other environmentally sound ways. 11. Analyse 12. Minimize Monitor and control the formation of by-products during a reaction. Design chemicals to minimise the potential for accidents. 12
Principles What is
GREEN Chemistry? approach to the design, manufacture & use of chemical products to reduce/eliminate chemical hazards
goal to create better, safter chemicals
choose safestt, most efficient ways to synthesize them
reduce wastes How is it Different? expect any chemical hazard can be controlled & managed
establish "safe" concentrations & expose limits
try to eliminate hazards from the beginning
derived from plants
do not contain hazardous artificial ingredients
biodegrade within 28 days (4 weeks) Eg. Use of Petroleum CHEMICAL INDUSTRY- relies on non-renewable petroleum
very energy intensice, inefficient & toxic
significant energy use & hazardous wastes
G.CHEMISTRY- "priotize use of alternative & renewable materials
chem. rxn. with the materials = less hazardous
principles: prevention of waste, less hazardous chemical suntheses & designing safer chemical Benefits Enviromental:
less wastes
safer products
protects enviro.
healthier workplaces
energy efficient Goals of Green Chemistry production of biobased chem. & fuels
invent rxns that reduce production of GhG
work in environmentalling benign solvents
harvest electricity for chemical synthesis
develop manufacturing methods using biocatalysis
advance g.chem. process & study of atmospheric chem.
convert biomass to synthetic intermediates, fuel & biodegradeable thermoplastics GREEN By: Sahajbir Atwal
& Preena Pannu Business
reduce costs
reduse waste treatment
fewer accidents
economical
protects human health /sustainable Use renewable raw materials, like plant materials, other than depleting ones.
Eg. Fossil fuels 4. Renew Green chemistry...
reduces toxicity, minimizes waste, saves energy, and cuts down on the depletion of natural resources. Putting Green Chem. Into Practice Develop integration plan by reviewing 12 principles
Assess chemicals used/manufactured
Indentify potential opportunities from g.chemistry
Establish an approach to adopt
Brainstom ideas leading to creation of lower environmental impacts
Integrate g.chemistry into business
Carry out regular reviews to monitor progress
How To Use Resources Efficiently Improve housekeeping
Separate waste to reduce costs
Recover pump/filter contents & tank washings
Avoid over-ordering
Store more liquids in bulk
Schedule production
Recover or reuse vessel-washing liquors
Reduce wastage from spills and surplus material
Prepare a mass balance
Operate & maintain equipment correctly
Reuse wash water for batch dilution
Monitor water consumption & effluent volumes
Buyer's Guide to Green Cleaning Chemicals

Most of the cleaning solutions that we use everyday contain over 80,000 chemicals. Even products that are “green” still contain dangerous chemicals and while other products don’t work at all. Cleaning professionals find it tough to formulate a product with the high demand of environmentally safe products.

Here are some things to look for when shopping green:



Key Features:

- Products should have a Material Safety Data Sheet (MSDS) listing all the ingredients

- Occupational Safety & Health Administration (OSHA) also lists chemicals it that are harmful

- Harmful chemicals found in cleaning preparations include: volatile organic compounds (VOCs), chlorine, benzene, triclosan, nonylphenol and nonylphenol ethoxylates, alkylphenolethoxylates (APEs), synthetics, terpenes, petroleum distillates, glycol ethers, caustics, builders and reagents.

- Look for a certification called Readily Biodegradable that indicates the formulas biodegrade by more than 90% within 28 days

- buy products that display all zero values on the National Fire Protection Association (NFPA) hazard diamond



Effectiveness:

Some products use nano- technology which pits tiny particles to work. These particles have the thickness of a piece of human hair. The small sizes of particles allow the nano- molecules to destroy the carbon bonds of dirt and bacteria, stains and build up. As a result, the dirt is broken into billions of particles that break up in water. In the end the particles are easy to remove which makes it highly effective.





All Patented Eco-Green® Chemicals Work at a Molecular Level

Cleaning products that contain harmful chemicals contribute the chances of getting cancer and other deadly illnesses. These conditions can occur in adults, kids, seniors and pets as these products are used at home, school, offices and other buildings. Finally, people have come to know that global warming is real and in effect. All types of dangerous products that include these dangerous chemicals are sent off into the atmosphere which lessens the quality of the air and increases global warming. There are many dangers to us humans by using these dangerous cleaning products. We have started to use these products more and we are getting exposed to them. There is an increase of cancer risk and also, many other complications in growth and behaviour. All in all, something needs to be done and everyone needs to do their part to prevent increase risk of cancer, premature aging and other deadly conditions.



Daimer's Exclusive Bio-Based, Eco-Green® Micro-Blasting® Technology Sets a New Green Chemical Industry Standard

- is completely harmless to the earth, water, air, humans and plants

- work at a molecular level surpassing all other ways

- particles are so small that forcefully dirt molecules are destroyed hence, the quick clean and effectiveness

- surfaces stay cleaner for a longer time

- this solution removes hydrocarbon residues like: petroleum derivatives, oils, fats, greases, sugars, and proteins
Eco-Green® is:

• Soap-Free Leaving Behind No Residue
• Bio-Based
• Readily Biodegradable
• Non-Toxic to Human, Animals, or Plant Life - In fact, there is no evidence of any adverse effects with respect to eye contact, swallowing, inhalation, or even skin contact or absorption!
• Non-Corrosive
• Non-Hazardous
• Non-Caustic
• Non-Flammable



Compare Green Carpet Cleaners, Regular Carpet Cleaners

There are two types of carpet cleaners: one that is environmentally friendly and another that works with dangerous chemicals. However, the one that works with dangerous chemicals is more popular because of availability and the fact that most people do not know how harmful these products are to the human health and the environment. The product that is environmentally friendly needs to become more popular because it is safer even if it contains some chemicals because they are safer than the chemicals in the average carpet cleaner. If water from carpet cleaning is disposed in a toilet or a drain, this causes additional environmental dangers. The water needs to be disposed properly which takes time. Using a green carpet cleaning product doesn’t cause this problem. Mostly everything that formulates a green carpet cleaner is all natural. These products only include plant- based materials. In addition, the results of using this product are the same as using the average carpet cleaning product. Chemist Chemists are scientists who study chemicals and how they interact with each other. Earnings:
