What do you think happened to all the old TVs and fridges that people replace every day? Sadly, most of them are lying somewhere in a dumpster idle and polluting the environment. Believe it or not, e-waste makes up almost half of the trash volume, but there are ways around it-recycling, repurpose, and reuse. Today, many initiatives like R3eWaste Electronics Recycling work tirelessly to see that e-waste is significantly reduced.

Below are the benefits we see so far.

The Conservation Of The Earth’s Resources

Most of these electronics are made of elements that are not easy to acquire. Things like silver copper and even gold take a long time to mine. And since they are being put back into the manufacturing system through reusing, this saves a substantial amount of the earth’s resources. Instead of resources being used to make more, they are redirected to creating other materials.

They Help Reduce Pollution

From the moment you dig the earth to get some of these components; you initiate a lifetime of pollution. There are noise pollution, water pollution, and soil pollution at one stage of creating these individual elements. When we recycle and reuse them, we significantly reduce these eventualities and even save on energy.

This Has Created A Lot Of Jobs

The collection, assembly, and sorting out of these materials have resulted in opening a whole new sector that was not there. This, in turn, has brought forth an opportunity for new employment channels, people depending on their expertise are getting new jobs to help with this process of making better use of e-waste.

Saves Land Space

These spaces that were used to dump these materials can now be put to better use, perhaps used for farming, agriculture, or settlement. Regardless, that piece of land that had only waste lying around can now be economically beneficial to the country.

E-waste Is A Great Income Generator

Scrap metal has always been a hot cake for a lot of companies in the past. These electronic waste materials can be sold off as spare parts to significant companies, becoming lucrative business ventures. Many companies have opened to manage only the collection of e-waste, others to transport it, and others to sort, sell, recycle, and repurpose it. All these new ventures are actively generating millions and millions of cash yearly.

The Take-Away

In an effort to lead better lives where we get to grow crops without the fear of getting poisoned or life in water coming to an end, we have to make sure that e-waste does not find its way to these locations. It is everyone’s responsibility that if we have something electronic that we want to get rid of, find companies willing to take them back in. Instead of throwing them in the trash to waste away, give the manufacturer a call and ask if they could take it. You never know, you might even get an upgrade of what you are disposing at a lower price.

In an era marked by the relentless progression of climate change, the pursuit of innovative solutions has led to the exploration of geoengineering technologies once deemed the province of science fiction. These ambitious endeavors, ranging from infusing clouds with sulfur dioxide to mitigate solar radiation, to the development of direct air-capture plants capable of removing carbon dioxide from the atmosphere, signify a pivotal shift in our approach to environmental preservation.

With last year recorded as the hottest in modern history, the escalation of natural disasters and the warming of oceans have underscored the pressing need for immediate and impactful action. In this context, the initiatives spearheaded by both new startups and established players in the fossil fuel industry highlight a complex landscape of innovation, ambition, and controversy.

The project undertaken by Occidental Petroleum in Odessa, Texas, exemplifies the potential and challenges inherent in direct air-capture technology. By sequestering carbon dioxide underground, this facility represents a significant step towards reducing atmospheric CO2. However, its dual role in facilitating further oil extraction raises questions about the long-term benefits of such technologies.

Contrastingly, Climeworks’ facility in Iceland presents a model focused solely on the reduction of greenhouse gases, without the complicating factor of contributing to fossil fuel production. This distinction underscores the diverse strategies emerging within the field of geoengineering, each with its own set of ethical, environmental, and economic implications.

The exploration of alternative geoengineering methods, including the release of sulfur dioxide into the atmosphere and the induction of phytoplankton blooms, further illustrates the innovative yet controversial nature of these interventions. While the potential to significantly impact global climate patterns is evident, the absence of comprehensive regulatory frameworks and international standards presents a formidable challenge to the responsible implementation of such technologies.

As we venture into this new frontier, the insights from David Gelles’ article in The New York Times offer a critical perspective on the evolving landscape of climate technology. With the market for geoengineering solutions projected to experience exponential growth, the dialogue surrounding these technologies is increasingly relevant to policymakers, scientists, and the global community at large.

In navigating the future of geoengineering, the balance between innovation and regulation, ambition and responsibility, becomes paramount.

Solar Powered Fresh Drinking Water

Chinese scientists have created a cheap and super-efficient sea water desalination solution that runs on solar energy.

The desalination system employs a Titanium-containing Layer that absorbs solar energy. The solar absorber consists of a unique paper on which they deposit the Titanium-containing layer which uses foam to float on the sea.

The Titanium layer heats rapidly when exposed to sunlight. It is this heat that vaporizes water. Sealing the unit within a transparent container with a slopy roof made of quartz allows the vapor to condense and the fresh water is collected.

Lead author Chao Chang explains that TiNO is already proven to be effective: “In the solar energy field, TiNO is a common commercial solar-absorbing coating, widely used in solar hot water systems and in photovoltaic units. It has a high solar absorption rate and a low thermal emittance and can effectively convert solar energy into thermal energy.”

Together, the scientists came up with an innovative way to deposit the TiNO using the magnetron sputtering technique.

The team worked with airlaid paper – a porous paper that supplies the contraption with seawater. It functions like a wicker.

They assembled three parts to create the evaporation unit: the airlaid paper at the very bottom, a thermal insulator, and the TiNO paper at the very top. Airlaid paper is a component of disposable diapers and is built from wood fibres.

The insulation is made using polyethylene foam and contains many pores filled with air that give the unit the buoyancy it needs to float on seawater. This keeps heat loss at a minimum.

“The porous airlaid paper used as the substrate for the TiNO solar absorber can be reused and recycled more than 30 times,” explained Chang.

The researchers wanted to minimize any negative impact of salt precipitation on the device’s efficiency. But they observed that there was no layer of salt on the TiNO surface even after a long while.

This might mean that the paper wicks are porous enough to keep salt from depositing on the TiNO, and that all the salt in the seawater goes back to the main reservoir of water.

Normal seawater is highly saline, at 75,000mg per liter. This is vastly different from normal drinking water whose salinity is only 200mg per liter. After going through the desalination unit, seawater goes all the way down to 2mg per liter of salt.

The Chinese team of researchers puts together a winning combination of affordability, high efficiency, and hygiene to create desalination that could help make fresh water available to people who face scarcity of water.

A Florida-based team of scientists suggested harnessing geothermal energy to desalinate water without using carbon fuels.
