4 Reasons Why LED Lights are Saving the Earth

Saving the Earth is on top of the list of most product designers these days. On a daily basis, we contribute to global pollution. From our homes to our jobs, lighting is a big factor in our everyday life. Our goal is to find life-changing ways to save Mother Earth from destruction.

Let’s start in places we usually go to like the house, office, restaurants, and malls. One of the factors contributing to environmental pollution is lighting materials. Most lighting materials increase the consuming of carbon footprint and chlorofluorocarbon. With the advancement of technology comes the birth of LED (Low Emitting Diode). It is the next big thing when it comes to interior and exterior architecture without compromising the Earth’s current state.

With these in mind, we have four convincing reasons why LED lights are saving the Earth.

Made of Non-toxic Materials

Unlike incandescent and other traditional lights, LED lights are made of non-toxic materials. This does not just affect the environment but as well as its users. LED lights are carefully manufactured with the idea that it frees the Earth from contamination and pollution. Efficient disposal is also what makes it environment-friendly. It alleviates the toxic waste produced by the material composition of traditional lighting.

LED lights are established to lower the environmental impact of lighting. The absence of mercury makes it easier to use and to dispose of. Traditional lighting can produce a toxic gas which can harm both the environment and the people.

Moreover, LED lights sold in the market is a big step to the people they cater to. They do not contribute to the increase in temperature because they don’t produce ultraviolet rays. Their excessive heat and vibrancy can cause a hazard to our environment.

Durable Lighting Design

What we loved the most about LED lights is their durable design. On average, an LED bulb can last from 10 to 15 years. Their lifespan is six times more than a traditional bulb. Even after a decade, the vibrancy of the light is maintained regardless of the daily usage. Since it’s energy efficient, it reduces the number of times required for replacing your lights. The longer lifespan offered by LED lights results to lower carbon emissions.

The durable lighting design of LED lights ensures the safety of the Earth. Lowered number of replacements mean lowered costs in purchasing, delivery, and installation of lights. In line with this, you get to minimize the waste product produced by your home or establishment. The composition of LED lights promotes the efficiency of utilization and disposal. Even at the last second, you get the best value for your money without compromising the safety of the Earth

Comes in Different Variants

Apart from the amazing specifications of LED lights, they come in different shapes and sizes too. The birth of LED lights introduced the art of lighting. Some light variants feature different colors and vibrancy you can play in just a click away. Smartphones and remotes are used to take control. Moreover, LEDs are more than just bulbs. They come in different types too. Bulbs, floodlights, decorative, strip, and downlights are what the LED light family is comprised of.

With these features, you can choose the best LED lights depending on utilization. Some can work indoors, outdoors, and some can be used in both. They are considered as a piece of unique lighting equipment because it gives you the ability to be creative with lighting design. You can use it for home and establishments’ to promote its atmosphere. These lights are commonly found in factories, restaurants, offices, streets, hotels, and walkways.

Energy-efficient Lighting

On average, you can save up to 90% of electricity costs with LED lights. Unlike traditional lighting, they are an economical choice. Their lighting capability will not require you to fill the room with a number of lights. LED lights are the best example of direct lighting. Lesser number of lights are required to give you the same amount of lighting as traditional lights. There is no energy wasted because it is capable of emitting lights in all directions.

Using LED lights are ideal especially for office buildings and factories. Since they light a bigger space, they save a bigger percentage designated for electricity. LED lights convert 95% of their consumed energy into light and 5% into heat. They will give you the same amount of light as traditional lights with 36 watts consumed. This is a big help to the environment considering that they will demand less energy from power plants and fewer greenhouse gases emitted.

Promotes Productivity

LED lights have different benefits for their users. They the ability to promote productivity since the lights give you a cool relieving feeling compared to incandescent. These lights enhance your sense of concentration and energy. Incandescent lights, on the contrary, give you a warm and lazy atmosphere. The heat they produce tends to make you feel cozy. That is why most occupational buildings switch to LED lights to give the employees a sense of focus.

Conclusion

Switching to LED lights alleviate the demand and pressure on the resources of the Earth. We save money and energy from using these and at the same time, we are saving our environment. Knowing that the quality and brightness are not compromised, it’s an economical choice to make. Use these 4 reasons as an eye-opener on why you should switch to LED lights!

CRISPR Gene Editing Set to Revolutionize Waste Management

When people think of waste management, gene editing probably does not come to most people’s minds. Yet the innovative CRISPR genome modification technology fits well within the confines of managing pollution and waste on the planet. In particular, scientists are looking at how CRISPR can help with bioremediation, or pollutant neutralization.

Why Neutralize Pollutants?

The planet is in dire need of help as the negative impact of climate change hovers on the horizon. One of the ways that researchers are revolutionizing waste management and environmentalism is by neutralizing the pollutants that are taking up space in our landfills and oceans.

Scientists have noticed that certain organisms are particularly good at removing toxins from pollutants while others have the advantage of immobilizing toxins. Researchers are connecting the dots in order to figure out how CRISPR can help make these processes more efficient.

CRISPR-Aided Bioremediation

While it is great that scientists have discovered microorganisms that can metabolize pollutants and produce less toxic matter, what if those properties could be expanded?

CRISPR researchers are trying to do just that by using genetic editing to transfer more advantageous genes to other organisms, thus giving them even more power over toxic pollutants. This would speed up the process of natural bioremediation techniques without adding high costs and dangers.

An Edge Over Traditional Techniques

Using CRISPR technology, especially the promising CRISPR/Cas9 lentiviral system, will not only speed up the process but it will do a better job than traditional methods of bioremediation. By using the gene editing technique, scientists can create more chemically superior microorganisms that have more advantageous enzymes. That results in better neutrality of harmful pollutants in the planet’s soil and oceans. In turn, this also ramps up molecular biodiversity, which improves the cleanup process.

Speaking of molecules, the CRISPR method targets different molecular processes within a microorganism’s cells, either to regulate an existing gene or to create an entirely new one. When looking at a particular gene, scientists analyze its ability to target pollutants as well as its process for remediation.

Enhancing Bioremediation with CRISPR

Experts need to keep several aspects in mind when improving the abilities of a remediating organism and ramping up its efficiency. First of all, they need to look at the molecular pathways that lead an organism to remediate or neutralize a pollutant. Are there changes or improvements scientists that can make to these pathways? What can they add or take away?

They do a similar thing with the organism’s enzymes. Next comes bioprocessing and biosensor development, which allows scientists to test the microbial cells for chemical testing and removal efficiency.

Removing Harmful Pollutants

Take mercury, for example, which is a metal that is harmful to the planet as well as those who live on it. The E. coli bacteria has a removal efficiency of 96 when it comes to eradicating mercury.

Scientists can take that Hg2 gene and transporter and perhaps transport it to another microorganism that can metabolize and neutralize another type of pollutant. Researchers continue to look at how this technique can help us clean up the growing number of pollutants in the environment.

It is not just microorganisms that they’re working on, either. Genetic manipulation in plants is another exciting endeavor that could help out in the bioremediation field. By looking at the detoxification processes in certain plants, scientists are trying to figure out how to use CRISPR technology to amp up bioremediation or, rather, phytoremediation efforts.

Some human genes could be especially useful to certain plants that can target heavy metals in the soil. Whether they enhance existing plant species or generate completely new ones, this is an exciting development in remediation efforts against pollutants.

Challenges in Hazardous Medical Waste Management

medical-waste-managementMedical waste management is a concern of healthcare facilities all over the world; about 10-20% of the facility’s budget every year is spent on waste disposal. According to the WHO, about 85% of the total amount of generated waste is non hazardous but the remaining 15% is considered infectious, toxic or radioactive. While non-hazardous medical waste poses less problems, the risks and challenges of hazardous medical waste management must be considered carefully, since incineration or open burning of hazardous medical waste can result in emissions of dangerous pollutants such as dioxins and furans.

For this reason, measures must be taken to ensure safe disposal of hazardous medical waste waste in order to prevent negative impact on the environment or biological hazards, especially in developing countries.

Health Risks

Biologically hazardous waste can be a source of infection due to the harmful microorganisms it contains; the most exposed are hospital patients, hospital staff, health workers. However, the situation is potentially harmful for the general public as well. The risks include chemical burns, air pollution, radiation burns and toxic exposure to harmful pharmaceutical products and substances, such as mercury or dioxins, especially during the process of waste incineration.

Other risks can also derive from the incorrect disposal of needles and syringes; worldwide, it is estimated that, every year, about 16 billion infections are administered. Unfortunately, not all needles are safely eliminated, creating risk of infection but also the possibility of unintentional reuse. Even though this risk has decreased in recent years, unsafe infections are still responsible for many new cases of HIV, hepatitis B and hepatitis C.

Environmental Impacts

Incorrect disposal of untreated healthcare waste can contaminate drinking and ground water in landfill, and also release dangerous chemical substances in the environment. Deficient waste incineration can also release hazardous pollutants in the air, and generate dioxins and furans, substances which have been linked to cancer and other adverse health conditions. Heavy metals, if incinerated, can lead to the diffusion of toxic metals in the environment.

The Way Forward

There is still a long way to go in order to ensure safe disposal of hazardous healthcare waste. A joint WHO/UNICEF assessment conducted in 2015 found that only 58% of analyzed facilities over 24 countries had appropriate medical waste disposal systems in place.

Strategies to improve healthcare waste segregation is an essential step in medical waste management

In the workplace, it is important to raise awareness and promote self-practices. Training in the areas of infection control and clinical waste management is important in order to maintain a clean, safe environment for patients and staff alike. Specialized industrial cleaning can also be effective in reducing risk of infection.

It is also essential to develop safe methods and technologies of treating hazardous medical waste, as opposed to waste incineration, which has already been shown to be ineffective and dangerous. Alternatives to incineration, such as microwaving or autoclaving, greatly reduce the release of hazardous emissions.

Finally, developing global strategies and systems to improve healthcare waste segregation is another essential step; since only about 15% of clinical waste is hazardous, treatment and disposal costs could be reduced significantly with proper segregation practices. Furthermore, these practices also reduce risks of infections for those workers who handle clinical waste.
