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.
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.
Farming Could be Transformed by Self-Watering Soil
The Texas University engineers have created a new kind of soil at Austin that pulls moisture from the atmosphere and distributing it to plant. Potentially the land has increased that can be farmed across the globe to formerly inhospitable areas and decrease water used in agriculture when droughts are growing.
ACS Materials Letters Journal has published the team’s details of the irrigation systems that draws in water from the air. Moisture absorbing gels capture atmospheric water. The gels release water after the soil has been heated to some temperature availing it to the plants. Some of the water that absorbs into the soil eventually finds its way back to the air, and humidity increases, and the cycle continues.
‘’Enabling free-standing agriculture in areas where it’s hard to build up irrigation and power systems is crucial to liberating crop farming from the complex water supply chain as resources become increasingly scarce,’’ Guihua Yu said, a materials science associate professor in the Mechanical Engineering, Walker Department.
Every soil gram can extract about 3-4g of water. It takes around 0.1-1kg of soil to water one square meter of farmland, depending on the crop.
Gels draw water into the soil during cooler nights in much humid periods and release the same moisture into the soil during the day.
Experiments were run by the team on the Cockrell School’s Engineering Teaching Centre Building on the roof to test the soil at UT Austin. The hydrogel soil retains more water than sandy soils from dry areas and needs less water to grow crops.
The team found out that the soil retained about 40% of the water amount it started during a 4-week experiment. Sandy soil still had only 20% water retained after a week.
The team had planted radishes in another experiment in both the soil types. Radishes survived for 14 days in the hydrogel soil without irrigation. They were only watered at the beginning to take hold. The radishes planted in sandy soil were watered for the first 4 days and then left without any irrigation. They lasted only two days.
‘’Most soil is good enough to support the growth of plants,’’ Fei Zhao said, a postdoctoral researcher from who led the study together with Panpan Zhang and Xingyi Zhou. ‘’It’s the water that is the main limitation, so that is why we wanted to develop a soil that can harvest water from the ambient air.’’
The first significant technology application the Yu’s group has worked on for over 2 years is water-harvesting soil. In 2019, the team innovated the use of hybrid materials made of gel and polymer, so called ‘super sponges’ that could extract large volumes of water from ambient air and clean it before releasing it. The technology was powered by solar energy.
The researchers have envisioned several other technology applications. Potentially it could be used to cool data centers, solar panels, and distribute drinking water to individual households or institutions.
This technology will enable nations to grow food on previously inhospitable land and feed a growing world population. There is already too much pressure on the available farmlands.
There is need to relieve pressure on the environment. Significant shifts in food consumption and land use are termed as necessary to hit 2050 goals by the UK. Many farmers in the UK are already making their farm operations more climate-neutral n 2035, with reports from several farmers that they are keen to achieve sustainability. Farmers in the UK grappling with the Covid-19 pandemic and the aftermath of Brexit have realized just how important it is to think differently.
When the Agriculture Bill was introduced by the UK government, brings with it rewards for farmers who tackle climate change and protect wildlife as an example of ‘public goods’ work. Considering that the UK is about to depart from the EU’s current subsidy system, It was necessary to have the new bill.
Genetic engineering has probably become a necessity because it is expected to help ensure global food security in the future. Several countries across the world are grappling with under nutrition and hunger alongside obesity. A third of the world population is undernourished in some way.
In the meantime, the University of Exeter researchers have estimated that 2 degrees Celsius global warming could lead to approximately 230 billion carbon tones released from the existing soil in the world.
The world’s soils contain at least double the carbon in the atmosphere, where increased temperatures heighten up decomposition, decreasing the time spent by carbon in the soil (which is known as ‘’soil carbon turnover’’).
The newest international research study published in the Nature Communications journal, led by Exeter University, discloses the soil carbon turnover sensitivity to global warming and eventually halves uncertainty in future climate change projections.
The projected 230 billion carbon let out at 2 degrees Celsius warming (which is higher than pre-industrial levels) could be higher than 4 times that of China’s total emissions and more than twice the USA’s emissions over the last century.
‘’Our study rules out the most extreme projections, but nonetheless suggests substantial soil carbon losses due to climate change at only 2 degrees Celsius warming and this doesn’t even include losses of deeper permafrost carbon,” co-author Dr. Sarah Chadburn, said from Exeter University.
The said effect on the world’s soil is known as ”positive feedback” – as climate change results in knock-on effects contributing to further change of climate.
What is the future for printing?
From the humble printing press to 3D printers – this is an industry that has experienced big change. Even in a digital world, printing isn’t dead either. According to Quocirca’s Global Print 2025 study, 64% of businesses said they believe printing will remain important to their daily business even by 2025. So here’s what we can look forward to in the future.
It will become more environmentally friendly
Millions of trees are used for paper and millions of cartridges are sent to landfill each year – but that trend is being reversed. We can anticipate that printing will become much more environmentally friendly in the future to ensure it keeps up with the times. Whether that is only using recycled cartridges and paper or buying high-capacity XL ink cartridges which can last longer efficiency and green concerns will be at the forefront.
Eco modes will be common in every model and will offer ever-greater eco-friendly performance.
The composition of ink has even been reconsidered to help it last as long as possible too. New formulae have been created to help reduce the ink drying up in the cartridge and it getting wasted.
3D printing will become more advanced
Printing has traditionally been a 2D affair – on paper, card, fabric and plastic. However, in recent times 3D printing has come into the mainstream spotlight. These use materials in place of ink or toner and formulate solid products.
The technology is now even being used to create organs.
- Researchers at the University of Minnesota created a 3D printed prototype bionic eye and in the UK scientists have used stem cells to 3D print human corneas.
- The Netherlands have printed a tooth which can kill bacteria.
- Switzerland has been successful in creating a 3D printed silicone heart.
This is where there is room to grow, however. 3D printed organs will transform medicine and enhance people’s lives. Currently, the silicone heart can only beat up to 3,000 times (the average heart beats 80 times a minute, meaning the 3D printed organ will only last 37.5 minutes). While this is a short time, it’s progress. A foundation has now been set and the future will probably see fully-functioning organs coming off the printer.
Printing will become easier
Printing has already been made pretty easy. Once upon a time, it was impossible to print a document without your computer being tethered to it by a cable. Now printers have wi-fi capabilities meaning you can click print on your laptop, computer, mobile phone or tablet – regardless of whether you’re connected with a wire or not. Some printers even have the ability to print when you’re not near it. In fact, you could be out shopping and want to send something to the printer for when you get home via a designated email belonging to your printer. In the future, we may see this become the norm on all printers, making the whole process of printing quicker and easier – and taking the current cutting edge functions to the mainstream.
AI could be an everyday appearance
Artificial intelligence (AI) can play a huge part in the printing industry. In an office setting, for example, it could help to enhance security – with printed materials being scanned to auto approve entry to buildings or access to a printer restricted to employees with the correct permissions.
An ‘intelligent’ printer can also provide forecasts on when you can expect to run out of ink or toner, or when you may need the printer servicing – and your printer could even order more for you.
Printing has already transformed and evolved so much and as technology also grows, we can expect printing to continue. From the humble printing press to being able to create a heart – printing is not dead yet.
Here’s Why Your Home Needs a Backup Generator
Having a backup generator for your home is one of those things that you probably don’t think about until the situation arises where you need one, and by this stage, it is too late as the lights have already gone out.
For most of us, we are connected to the national grid and we live in built-up areas where there is little threat to our power supply. However, in these uncertain times of climate change, we see many more natural disasters that could lead to power outages.
Here we are going to take a look at the reasons why your home needs a backup generator.
To Preserve Food
When the power goes out we are more than likely to be faced with a fridge and freezer full of perishable goods, and the chances are we are not going to be able to replenish our stocks anytime soon. We are no longer using preserving techniques such as pickling and salting so our food will quickly spoil. If we were prepared and had a backup generator then this would kick in the second we lose power from the grid and our lifesaving food supplies would be saved. When you have a house full of children the last thing you want is to be without food, so make the sensible decision and install the generator.
To Continue Working
In these times of heightened mobility, we are working from home more and more and as the recent Coronavirus pandemic has shown us, normal routines can change very rapidly and we can find ourselves unexpectedly working away from the office. Our work will invariably mean using a laptop and phone so having a power supply is paramount. Without a backup generator, you will struggle to earn money and also run the risk of losing any unsaved work on your computer which could set you back years and end up costing you a fortune. Use the 10 Power Up calculator to figure out the size of the generator that you need to power your home.
As crime rates have gone up most of us have responded by installing security alarms and lights around our properties to protect us from intruders. However, in times of power outages, these will be useless and our homes and families will be left undefended. Furthermore, power cuts are often caused by natural disasters and sadly we often see cases of civil disobedience and rioting during these times so it is twice as important to know that your property is safe and sound.
Whilst you might primarily have bought a generator for your home, if you buy a portable one rather than a secured unit, you could use this for camping trips and excursions, or to power work tools away from the house. In this instance, it is wise to speak to professionals from https://krugerpower.com.au/ who will advise you regarding the best model to buy for your needs. This way you can be safe in the knowledge that your home backup power supply is secure, but you can also make use of your investment away from home, thus making a generator a more attractive purchase.
An Alternative Car Charger
We are all adopting greener ways to live our lives and one of the main ways we do this is by cutting down on fossil fuels. We are buying more electric and hybrid cars and these need charging, however, due to infrastructure problems it can often be difficult to find a convenient charging point, and when we do it can take hours to fully charge our car. If we had invested in a generator this could be stored in the car on long trips, thus allowing continuous travel without the need to deviate to find charging points.
To Preserve Water Supply
Some of us live in rural areas and we are not connected to mains water, therefore we rely on groundwater and a well to keep ourselves alive. Whilst some of these wells can be pulled by hand the majority need a pump to extract the water and then to filter it to make it potable. Without your backup generator, this becomes a much tougher task, so it makes sense to secure your water supply as well as preserving your food by investing in a backup generator.
These days we need our communications, even more than ever because we have become a 24-hour society that is highly connected through the internet. We don’t just use the internet for pleasure, we also use it to stay safe by always being in contact with the authorities and our loved ones. Mobile phones and fixed-line phones also require electricity to charge and work, so it is vitally important we keep these lines of communication open by investing in a backup generator, otherwise we would lose contact with the outside world.
To Safely Live Rurally
If you live rurally having a generator can mean the difference between life and death. The outback is an inhospitable place at the best of times, but when natural disasters strike, being left without power would be a disaster. It would mean no access to food, water or heating, and livestock would almost certainly perish. The more rurally you live the longer it would take for any would-be rescuer to reach you, so the only sensible option is to invest in a backup generator to keep yourself alive in the meantime.
As we have discovered there are a myriad of benefits to investing in a backup power generator for your home. In times of natural disasters, it could mean the difference between life and death, especially if you live in the outback, following a loss of power, your only access to safe food and water and communications systems is through having a backup power generator. There are also secondary benefits as a portable generator could also assist with charging electric cars and bikes and can also be used for leisure purposes such as providing a power supply to an outdoor party or when you are on a camping trip. All in all, buying a backup generator gives you peace of mind during turbulent times, so it is a very worthwhile addition to your home.
