Turning waste into valuables

Hi,
So this post was requested on Twitter after our September Top Tips about recycling. Today we will be talking about how to turn complete waste into something reasonably valuable. This is basically a form of upcycling but to a more extreme level.

1. Ecobricks

So, almost a year ago we did a post about ecobricks, but they are such a good example of turning waste into valuables that we decided to put it here anyway.
Ecobricks are a building material made from plastic. The waste plastic is washed and then compacted into a clean plastic bottle (also waste). The bottle becomes very hard and durable. Multiple bottles can then be used as bricks and cemented together.
The 'bricks' are strong and do not decompose. For more info, read our post where we go into more detail.

2. Metals

Although this may seem like something not worth the time. When you separate the metals in waste (for example an old car), you can get usable metal out of it. Seeing as metal doesn't decompose over time, it can be used again and again. Some manufactured items contain precious or rare metals which are actually quite valuable. So if these are separated from the rest of the waste, they can be sold for the same price as they were before being manufactured.

3. Leather

Some leather companies will use the hides of already dead animals for their leather production. These skins often come from the meat/dairy industry and would otherwise be considered waste. However, certain companies claim to use these skins and save millions of tons of waste from landfills. These claims cannot always be trusted, seeing as, after many meat production procedures, the animal skins would not be reusable. But at least it's a start.

4. Paper byproduct

There are now hopes of turning a byproduct of paper production into quite valuable chemicals that can be used to make nylon. This method would have environmental benefits when it comes to energy usage and chemical waste. About 50 million tons of 'kraft lignin' are created in paper production each year. It would normally be burned, producing carbon dioxide, which then fuels the climate crisis. So this new solution is very exciting.

5. Energy

So this is the most problematic option on this list. Turning waste into energy is a widely used solution. Normally waste will be burned creating light and heat, which can be converted into electricity. With the current energy shortages, this seems like a great solution. However, the burning of waste releases huge amounts of CO2. It also destroys materials that could have been reused. So, this is a quite controversial form of producing electricity. I am hoping to write a post where I talk about this in more depth, so keep your eyes peeled.

The life of ... an alcon blue butterfly

Hi everyone, Today we are going to be looking into the life of an alcon blue butterfly (Phengaris alcon). After mating, the females lay their eggs on marsh gentian, a blue-coloured wildflower. The eggs can only be laid on these flowers, as this is what the newly hatched caterpillars will eat. Although in some alp regions, they can also be found on willow gentians, a close relative of the marsh gentian. Once the caterpillars have hatched from the eggs, their main predator and danger are the ants that swarm below. But high on their plant homes, the caterpillars are safe. However, this isn't where the alcon blue caterpillars are going to stay forever. Eventually, they drop down to the ground using silk strings. With no protection, they are soon dragged off by the ants. The most amazing part is, the alcon blue caterpillars give off the same scent and chemicals as the ant larvae. So the ants take the caterpillars back to their brood chamber, wher...

Eco system Galápagos: Part 1 Geography

Hello and welcome to the first post about the Galapagos Islands. Currents and Winds The volcanic islands of Galápagos started to form 4 million years ago. Where they lie, is unique. They are situated directly on the equator, on the Nazca tectonic plate. The Galapagos Islands are on the crossroads of three currents. The cold South Equatorial Current flows westward towards Galapagos. The warm Panama Current runs in from the north. And finally, the deep sea Cromwell Current runs from the west. The Galapagos Islands are also where the Northeast Trade Wind meets the Southeast Trade Wind. Galapagos Hotspot 21 Volcanoes make up the Galápagos Islands with 13 still active. The reason for this volcanic activity is a giant hotspot under the island. A hotspot is a gigantic column of super heated molten lava, rising up towards the surface. It is immense; at least sixty miles (97 kilometers) across and 1800 miles (2897 kilometers) deep. It connects the islands to ...

Animals 11-15 in our '50 incredible animals' series

Hello, We have another five amazing animals for you today. Enjoy! 11. Dhole This is a dog species which looks rather like a red fox . They are difficult to put into any of the dog subfamilies. They aren't foxes, nor wolves, nor domestic dogs. Dholes are fast runners and live in packs of 5-12 individuals. Although sometimes, different packs will join forces to become a pack of 30 or more individuals! However, these super packs are broken up after a successful hunt. The different packs rarely attack each other as neighbouring packs are often closely related. Dhole packs live in burrows with multiple entrances. They can be found in eastern and southern Asia. They eat wild berries, insects and lizards and as a pack hunt deer, rodents and other wild mammals. Interestingly, unlike other dogs, they rarely kill by biting at the throat. They are also good swimmers! 12. Irrawaddy dolphin The Irrawaddy dolphin can be found in coastal areas of south a...

June 2021 Factfile - some news from the past month, animals and our first plant of the month!

Hi Everyone! We’re terribly sorry for missing last month’s fact file (May). We have all had a busy few months. This is actually the May fact file coming out very late. The June fact file is cancelled. Because of this, this factfile contains news from both months. We are very sorry for the delay in this post. As announced in our last factfile, this post has a new feature to it; plant of the month. We hope you'll enjoy it! News: Sierra Leone has sold a rainforest for a Chinese Harbour Sierra Leone has sold 250 acres of beach and protected rainforest for £39m to build an industrial fishing harbour. It was home to many animals, including several endangered species. This will also have a disastrous impact on local communities, tourism and as I've already mentioned, the environment. Just click here - It's an article about all the environmental disasters that happened in May. It shocked me. Red Squirrels were born ...

Sustainable food choices challenge

Hi everyone, Welcome back to our second challenge! Today we're talking about sustainable food choices. 1. No meat on Mondays challenge The production of meat, especially beef, is resource-intensive and contributes significantly to deforestation, greenhouse gas emissions, and water pollution. By dedicating one day a week to plant-based meals, you can decrease your carbon footprint and help to reduce the strain on natural resources. This challenge encourages a more sustainable and ethical approach to food consumption, gaining a better understanding of the environmental impact of meat production. Reducing meat intake is also associated with health benefits, including lower risks of heart disease and certain cancers, making it a win-win for both your personal well-being and the planet. 2. Local / seasonal eating challenge Choosing local and seasonal foods is important in helping to reduce the environmental impact of food production and transporta...

The life of ... Atlantic salmon

Hello everyone, Today we're talking about Atlantic salmon. Atlantic salmon are found in the north Atlantic and the rivers that flow into it. They can grow up to a meter long and are classified as Least Concern by the IUCN . Atlantic salmon start their lives in rivers. The pea-sized eggs are laid in autumn and hatch in April or May. The tiny salmon are called alevins. They feed on aquatic invertabrates and eventually devolop into parr. Parr are easily recognised by destinictive patterns and markings on their flanks. After up to several years, the parr develop a silvery sheen. These replace those characteristic parr markings. Their bodies change in preparation for the salt water and they are now called smolts. They swim downstream with the current all the way to the ocean. In the deep sea waters, the smolts feed on crustaceans and small fish for 15-50 months. However they are hunted by a number of predators including, sharks, seals and of ...

10 animals on the edge of extinction you didn't know about no. 9 - South Island takahē

Hello Today we’re talking about the South Island takahē, porphyrio hochstetteri . They are flightless birds, endemic to New Zealand. Takahē are brightly coloured and weigh 2.3-3.8 kg. They have red legs and a large red beak. Their feathers are coloured blue and green. They have wings, but these are only used during courtship or rivalry displays. They are territorial, with one family’s territory reaching anywhere from 4 ha to 100 ha (0,04-1km^2). Pairs will live in the same territory each year. They breed once a year and will raise 1-3 chicks (normally 2) each year. Both parents raise the chicks together. In the wild, takahē live in native grasslands and have a lifespan of 16-18 years. If snow covers the ground then they will move into nearby forests. They eat tussock grasses, sedges and sometimes rushes. But they are opportunists, so they will occasionally go for insects or even ducklings and...

10 Animals on the Edge of Extinction No. 10- The Javan Rhino

The Javan rhino is listed as the 1st animal on WWF’s list of the 10 world’s most endangered animals, and I for my part, had never heard of it! If you hadn’t either, we’re changing that now. A bit about the rhino’s lifestyle The Javan rhinos are now exclusively found on the island of Java in Indonesia, but were once found in vast regions of northeast india and Southeast Asia. They have a dark grey colour which looks almost black when wet, and their (often pink) skin folds look a bit like plated armor. Both males and females have lower incisors which resemble tusks that they use to fight. Males have one relatively short horn of about 25 cm (10 inches). Javan Rhinos live in tropical forests, marshy areas and in the thick bush. They are mainly browsers and eat over 100 plants species they find in the forest, weigh between 900 and 2300 kg (1984-5071 pounds) and are between 3 and 3.2 meters (10- 10.5 feet) long. How endangered are we talking? Javan rhinos are the most ...
