THE PACKAGING INDUSTRY’S PUSH TOWARDS PLASTIC-FREE PACKAGING

No Comments

The global push for sustainability is forcing the packaging industry to reassess its use of single-use plastics. In recent years, it’s become increasingly clear that these plastics are significantly harming the planet; particularly our oceans.

In a bid to reverse the damage, the packaging industry is now pushing towards plastic-free packaging. Here, we’ll look at the changes taking place in the industry, and what alternatives there are to plastic packaging.

What steps is the packaging industry taking?

There are a lot of changes taking place in the packaging industry in order to tackle single-use plastics. Major brands have also been doing their part to ditch their plastic packaging, opting instead for more environmentally friendly options.

Unilever, Procter & Gamble, Coco Cola, Nestle and Danone are just some of the big brands taking part in a Loop scheme. The scheme involves providing customers with reusable, returnable containers instead of their current single-use plastic packaging. The scheme is currently being trialled starting with New York and Paris. If successful, it will start to be rolled out worldwide.

What packaging alternatives are available?

Suppliers are also starting to focus on offering alternative packaging solutions. There are a number of plastic alternatives businesses can use, including paperboard, corn starch and even seaweed. The latter has been used to create innovative, edible plastic-free water bottles in the UK.

Courier companies such as TNT, have seen a notable change in the packaging used for parcels today. As businesses look to become more sustainable, they are exploring the different packaging options such as paperboard.

The benefits of utilising plastic free packaging

There are lots of benefits which come from switching to plastic free packaging. Mostly, it’s extremely beneficial to the environment. Reducing single-use plastics lowers our carbon footprint, while also protects the oceans. There has been a lot of media attention given to the shocking damage plastics are having on the planet’s wildlife, something we can all work to eliminate.

Another benefit is that non plastic packaging tends to be free from allergens and toxins. Consumers are always looking for products which are better for their health and wellbeing. So, companies which do offer plastic free packaging are going to see a rise in business. Customers will actively choose a brand which shows it cares about sustainability, than one which doesn’t.

One of the biggest climate threats is the most familiar: Rain

At least it wasn’t another Katrina.

That’s the silver lining many people seemed to cling to in the wake of Hurricane Barry (quickly downgraded to Tropical Storm Barry), which made landfall in Louisiana on Saturday. The storm had modest wind speeds — 74 miles per hour compared to Katrina’s 174 — but still delivered torrential rain, overtopping levees in several counties as it continued to crawl over parts of Mississippi, Arkansas, Missouri, and Tennessee at a lazy 9 miles per hour.

Though the big, soggy storm underperformed according to most forecasts and moved slower than your average bicyclist, government officials continued to urge residents to be cautious. When we talk about extreme weather — something the vast majority of experts say we should expect more of in the coming years — most people assume the greatest danger will be in the form of something new: record-breaking hurricane windsoff-the-charts heat waves, or regionally shifting conditions. But as Barry proved, one of the most insidious effects of climate change might be something with which most places are already somewhat familiar: rain.

The last 12 months have been the wettest in U.S. history. Spring flooding drowned huge swaths of the Midwest this year, wrecking communities and essentially turning farms into inland seas. Floodwaters overwhelmed levees in the nation’s heartland, drenching towns and causing billions of dollars in infrastructure and crop damage. During May, a stormy pattern boosted the national monthly precipitation average to the second-highest level on record, according to the National Oceanic and Atmospheric Administration. The seemingly endless rain proved to be a chaotic maelstrom for farmers: Farmers were able to plant only 58 percent of the corn crop (compared to 90 percent at the same time last year), and soy planting this May was forced behind schedule by over 30 percent.

Heavy rainfall can be just as damaging to crops and cities as drought and extreme heat, and the U.S is slated to experiencing more of both. This June, for example, a slow-moving storm unloaded more than a month’s worth of rain across parts of the Southeast while the usually chilly Bay Area (as Mark Twain reportedly said, “The coldest winter I ever spent was a summer in San Francisco”) hit an unheard of seasonal high of 100 degrees F.

In many regions with high precipitation, scientists predict we’ll continue to see more extreme rainfall. As NOAA stated in a 2018 report, “Annual flood records are expected to be broken again next year and for years and decades to come.”

More than 70 percent of the planet’s surface is water, and as the world warms, more water evaporates from oceans, lakes, and soils. As average temperatures rise, air acts like a sponge that can hold on to more moisture. For every 1 degree Celsius (or 1.8 degrees Fahrenheit) of warming, the air can hold 7 percent more water. That moisture then falls as extreme rain. Additionally, climate change makes storms migrate at a lazier pace, enabling them to drop far more rain on a given region, leading to an increased risk of devastating floods. In these ways, climate change forms an ideal brew for perfect thunderstorms.

Take Hurricane Harvey, for example. When the storm approached the Texas coast almost two years ago, it was clear it would be one for the ages. It dumped more than 30 inches of rain on 6.9 million people, while 1.25 million experienced over 45 inches and 11,000 had over 50 inches. The result was catastrophic flooding in the city and surrounding area that caused an estimated $128 billion in damage and killed 89 people. Four attribution studies have found that human-caused global warming likely made Harvey’s rains heavier.

“Harvey was the most significant rainfall event in United States history in scope and rainfall totals since rainfall records began during the 1880s,” U.S. Geological Survey scientists wrote in a study last year.

In more recent memory, Hurricane Florence lingered like an unwanted house guest after it plowed into North Carolina as a Category 4 beast last year. It unleashed a record-setting average of 17.5 inches of rain over an area of 14,000 square miles. At least 53 direct or indirect deaths were blamed on the storm. According to a first-of-its-kind experimental “pre-attribution” study done as the storm was approaching landfall, climate change made Florence’s most intense rains over North Carolina more than 50 percent greater in magnitude than they would have been otherwise.

In addition to passing legislation to reduce emissions, cities can invest in infrastructure to avert future weather-related disasters. After Hurricane Katrina, New Orleans beefed up its levees and floodwalls. New York City awarded funding to a massive flood wall along the southern end of Manhattan. Other flood-prone metros are, essentially, making room for excess water: Chicago has built more than 100 “Green Alleys” — permeable pavement that allows stormwater to filter through and drain into the ground. After Hurricane Sandy, Hoboken, New Jersey, rebuilt with future storms in mind — replacing concrete with spongy surfaces and installing a 200,000-gallon stormwater tank under one of the city’s big parks.

People can also take individual precautions when it’s really coming down outside. “Heavy rainfall forecasts should be taken seriously,” said Dr. David Novak of NOAA’s Weather Prediction Center in a 2018 interview. He recommends being aware of your flood risks, like living in a low-lying area. Knowing your evacuation routes and heeding official warnings are key to staying safe. “Most flood-related deaths occur in vehicles,” he said. “It only takes one foot of water to sweep your vehicle away.”

Hydro Powered Irrigation System to Enhance Food Security

No Comments

Today, more than one billion people in the world suffer from hunger. The only sustainable solution to the problem of food scarcity is to increase food production in existing arable land. Improving irrigation in the developing world where such facilities are not available due to economic and topographic reasons can be an effective way to increase food production because proper irrigation can increase food productivity between two to five times that of normal production.

For areas where irrigation facilities have not reached farmers despite having a water source nearby, aQysta has developed an affordable and sustainable solution: Barsha Pumps. Barsha pumps are a hydro-powered irrigation system, a sustainable solution that does not use any external source of energy like fossil fuels or electricity and can be used to irrigate lands within 25 meters from a flowing water source. Farmers throughout Asia, Africa and South America have challenges irrigating despite being near a water supply.

Barsha pumps work on the spiral pumping principle – developed during ancient Egyptian times – but have never been applied on an industrial scale before. The kinetic energy of a river is used to rotate a water-wheel powered spiral, which pumps water by the alternating compression and decompression of air.

Barsha pumps are designed by optimizing the spiral pumping principle. They are crafted to be compact and easy to handle, with multiple spirals instead of one, which helps transport a greater volume of water. Modular design and only one moving part make Barsha pumps easier to standardize and maintain.

Apart from the product innovation, the business model in which we aim to implement the solution is also unique, involving local communities in manufacturing and maintenance of the irrigation systems which help to increase socio-economic prosperity in developing countries.

The major benefits of Barsha pumps are:

· Zero operating costs

· Two to five times greater agricultural productivity by providing year-round irrigation

· Return on investment for farmers within one year compared to approximately 10 years of diesel pumps

· Low maintenance due to only one moving part

· Zero Emissions: Barsha pumps produce zero emissions and replace fossil fuel pumps which produce 150-300 kg Co2 per hectare irrigated land per year.

Barsha pumps are about 1.5 meters in diameter and can pump water up to a height of 25 meters at a maximum flow rate of one liters/second. The pumps can be used as a stand-alone water pump to supply water to the field or can be combined with other complementary irrigation technologies like drip irrigation system and sprinkler irrigation system.

The target market for Barsha pumps are agricultural economies in Asia and Africa where more than 72 percent of world population live. In those regions, only 20-30 percent of the cultivable lands are irrigated and urbanization is increasing.

The primary market for aQysta is Nepal, a south Asian country where only 4.5 percent of land in the hilly area is irrigated year-round despite having more than 6,000 rivers across the country. More than 76 percent of the population in Nepal is dependent on agriculture, but most people do not have access to irrigation for topographic and economic reason. We have estimated a potential market of around 100,000 pumps in the country.

Currently aQysta is working with IDE Nepal to install Barsha pumps in six pilot locations in Nepal. The pilot project is expected to be finished by March 2013.

After Nepal, aQysta is planning to grow globally and have already received interest from countries like Sri Lanka, Rwanda, Mozambique, India and Ecuador.
