Solar Photovoltaic (PV) energy is quite a hype in recent world of renewable energy. We know it convert sun's light energy into electrical energy. With…
What are all these symbol means on the product packaging ? lets find out.
It is very common to find symbols on product packages, which to the naked eyes an art, but it does convey important messages on how to handle it properly and how to dispose them correctly. Improper disposal may cause harm to the environment as we know it.
Lets learn to recognize them and act according to the specification. Your next correct move may means save the environment or the people you love.
The Not Suitable for Children under age 0-3 symbol denotes a chocking or suffocation hazard of the product.
75 percent of choking deaths occur in children under the age of 3 years. This is partly because they tend to explore their world by putting things in their mouth.
This symbol usually appears on products with loose or small parts, including small lithium cell batteries (button batteries), beads, marbles, balloons, small magnets (often found on refrigerators or in magnetic toys), small toys, and even clear plastic bags (suffocation hazard).
The period-after-opening symbol identifies the useful lifetime of a cosmetic product after its package has been opened for the first time.
The time period is most often represented compactly as a number of months, followed by the letter “M”. It can range from 3M, 6M, 9M, 12M, 18M, 24M to 36M.
As part of the Hazardous Waste, the Flammable symbol identify flammable or Ignitable wastes. Ignitable wastes can create fires under certain conditions, are spontaneously combustible, or have a flash point less than 60 °C (140 °F).
These waste should handle with care and should not expose to heat source or burn. Such symbol are commonly found on aerosol products and fuel products.
The international symbol for “food safe” material is a wine glass and a fork symbol.
It is important to know that all the material that is in contact with the food (includes food and water containers, packaging materials, cutlery etc) are safe to use with food.
Food contact materials can be constructed from a variety of materials like plastics, rubber, paper, coatings, metal etc.
During the contact of the food contact materials with the food, substances can migrate from the material to the food, which including loose materials and toxic contaminants.
This tidy man symbol is from Keep Britain Tidy campaign asks you not to litter. It doesn’t relate to recycling but is a reminder to be a good citizen, disposing of the item in the most appropriate manner.
This symbol can be found in lunchbox and containers from fast food franchise.
There are many variant to the “do not litter” symbol, but all bring the same meaning. Lets not only keep Britain Tidy but keep the World Tidy.
RoHS is a directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment. RoHS motivated in part to address the global issue of consumer electronics waste.
RoHS is often referred to as the “lead-free directive”, but it restricts the use of the following ten substances:
The Waste Electrical and Electronic Equipment Directive (WEEE Directive) is the European Community Directive 2012/19/EU on waste electrical and electronic equipment (WEEE). The WEEE Directive set collection, recycling and recovery targets for all types of electrical goods. It is part of a legislative initiative to solve the problem of huge amounts of toxic electronic waste.
Hazardous electronic comprise of Lead-acid batteries, Cathode ray tubes, Fluorescent tubes, backlights to laptop screens, thin-film transistors, polychlorinated biphenyl (PCB) circuit boards, Fridges and freezers. Do not throw them in general waste bin or landfills as the hazardous material can have long term damage to the environment and human health.
Lead is one of the Hazardous Material that is not suitable to be dispose directly to general waste bin or landfills.
Lead is a heavy metal that is denser than most common materials. It have low melting point, ductility and relative inertness to oxidation. It is extensive use in construction, plumbing, lead-acid batteries, bullets and shot, weights, solders, pewters, fusible alloys, white paints, leaded gasoline, electrical and electronic equipment and radiation shielding.
However Lead is a neurotoxin that accumulates in soft tissues and bones, damages the nervous system (causes permanent brain damage), interfering with the proper functioning of enzyme, and causes blood disorders.
Lead can disperse in air, soil and water if improperly handled, hence such waste need to be properly recollected and recycle. Lead can accumulate in soils, and remains for hundreds to thousands of years, affecting plants and other organism.
“CE” originated in 1985 as an abbreviation of Conformité Européenne, meaning European Conformity. CE marking is a certification mark that indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA).
The recycling symbol comes in few variant, but nevertheless the famous international recycling symbol had been well recognized worldwide.
This symbol was designed by Gary Anderson. He was 23 years old when he entered a design competition held in conjunction of the first Earth Day on 1970 by the Container Corporation of America which asked contestants to create a symbol for recycled paper.
The three arrows can be explained by “Reduce, Reuse, Recycle” , it forms a Möbius loop.
The Taiwan’s recycling symbol features four external arrows which also create a negative space within to form another four arrows pointing outwards.
The Green Dot represent the European network of industry-funded systems for recycling the packaging materials of consumer goods. The basic idea of the Green Dot is that consumers who see the logo know that the manufacturer of the product contributes to the cost of recovery and recycling.
