Student uses catfish fat to create bioplastics

Last update 07:10 | 08/01/2018
VietNamNet Bridge – Vu Thị Mai Anh, 23, a student at the Hanoi University of Education, has conducted research on isolating and selecting bacteria capable of converting basa fish (catfish) fat into Polyhydroxyalkanoates (PHA).

After being subdivided and selected, microorganisms are cultured in catfish fat and converted into environmentally friendly bioplastics.

The research won first prize in the field of food technology at Euréka 2017, a contest for technology students organized by the HCM City Youth Union. Tiếp tục đọc “Student uses catfish fat to create bioplastics”

Top 10 HAPPY environmental stories of 2017

Mongabay.com

  • Throughout 2017, scientists discovered new populations of rare wildlife, and rediscovered some species that were previously thought to be extinct.
  • Some countries created large marine protected areas, while a few others granted land rights to indigenous communities.
  • In 2017, we also saw the ever-increasing potential of technology to improve conservation monitoring and efforts.

The past year may have seemed like doom and gloom for the environment, but there was plenty to be thankful for. So once again, we bring you some of the happier environmental stories of 2017 (in no particular order). These include rediscoveries of species that were once thought to be extinct, local communities being granted land rights, and the emergence of new technologies that are boosting conservation efforts.

1. New populations of rare wildlife were found

This year, conservationists discovered some new populations of threatened wildlife. Take, for example, the helmeted hornbill (Rhinoplax vigil). A research team recorded a new and “unexpectedly rich population” of this critically endangered bird in western Borneo. For a species that is now nearly extinct because of poaching, this discovery boosts hope for its future.

It was good news for the Grauer’s gorilla (Gorilla beringei graueri) as well. Surveys in the Democratic Republic of Congo’s Maiko National Park revealed several previously uncounted individuals of Grauer’s gorillas in just 1 percent of the park. The researchers think that there might be many more gorillas living inside the largely unexplored 10,885-square-kilometer (4,000-square-mile) park.

Mời tham gia khảo sát về chất lượng không khí tại Việt Nam

️MỜI THAM GIA KHẢO SÁT VỀ CHẤT LƯỢNG KHÔNG KHÍ VIỆT NAM 2017 tại đây  http://bit.ly/ONhiemKhongKhi

Quan sát trong hai năm qua cho thấy, ô nhiễm không khí là một trong những chủ đề môi trường, xã hội và kinh tế rất đáng quan tâm ở Việt Nam.
♻️ Chất lượng không khí ở Việt Nam đang trong tình trạng đáng báo động. WHO đã có thư gửi đến nhân viên của họ tại Hà Nội để cảnh báo về vấn đề ô nhiễm không khí đang ở mức nguy hiểm tại Hà Nội thời gian gần đây. Trong thời gian tới, không khí ở Hà Nội sẽ tiếp tục duy trì tình trạng này, và có khả năng đạt ngưỡng như các thành phố ô nhiễm nhất thế giới như Dehi (Ấn Độ), Bắc Kinh (Trung Quốc) và Ulaanbaatar (Mông Cổ).

Ocean plastic pollution – what role can social science play?

29 November 2017

IDS is partnering with the EU, UN, Chatham House and other organisations to host a high level side event on circular economy solutions to tackling ocean plastic pollution, during this year’s United Nations Environment Assembly in Nairobi (4-6 December). The event will showcase specific examples of collaborative action and policies that aim to reduce plastic waste, address unsustainable consumption and production patterns and redirect investment for a clean, efficient and circular economy. Ahead of the event, I want to highlight the importance of a universal development approach and transformative social science research, as solutions to the ocean plastics problem.

Ocean plastics pollution – not just an environmental issue

Plastics pollution of oceans has emerged as a major global environmental crisis. Between 4.8 and 12.7 million tonnes of plastics enter the ocean each year. It is devastating for marine ecosystems and the accumulation of microplastics in food chains pose a risk to human health. And the issue is becoming more serious.  By 2050, plastics production is expected to increase to over 2000 tonnes per year, up from 311 million tonnes in 2014.

Plastics end up in the ocean as the result of chains of human activities in different parts of the world. We are all contributing to it. China, Indonesia and the Philippines have been identified as the top three sources of ocean plastics pollution by the Ocean Conservancy. While litter found on the sea floor around the UK has risen 150% in the last year and UK plastic waste drifts to the artic where is has a very damaging impact on one of the most vulnerable ecosystems in the world.

Conserving Forests Could Cut Carbon Emissions As Much As Getting Rid of Every Car on Earth

Cantonal Hojancha was once a major cattle ranching region. Most of this area was cleared for pasture only 30 years ago. Now, many of the residents have moved into the service industry, and the pasture land has slowly converted back to forest. Photo by Aaron Minnick (World Resources Institute)

New analysis from The Nature Conservancy, WRI and others estimates that stopping deforestation, restoring forests and improving forestry practices could cost-effectively remove 7 billion metric tons of carbon dioxide annually, or as much as eliminating 1.5 billion cars—more than all of the cars in the world today!

In fact, forests are key to at least six of the study’s 20 “natural climate solutions,” which could collectively reduce 11.3 billion metric tons of greenhouse gas emissions per year. That’s as much as halting global oil consumption, and would get us one-third of the way toward limiting global warming to 2 degrees C (3.6 degrees F) above pre-industrial levels — the threshold for avoiding catastrophic effects of climate change — by 2030.

Stopping Deforestation Offers the Biggest Benefit

Plankton decline hits marine food chain

DW_Plankton is the basis for the entire marine food web – and it is under threat. From the Mediterranean to the Pacific, animals have been struggling to survive, due apparently to changes with plankton.

Food chains represent the greatest interdependency within the webs of life. The marine food chain, for instance, is essential for oceans – and depends on plankton. But environmental changes and human activities may be threatening plankton– and therefore all marine animals.

According to a recent study,the biomass of sardines and anchovies has been decreasing at alarming rates in the Mediterranean Sea. At the same time, sea lions are struggling to forage on the coasts of California. Both cases have shed light on how a single food chain element can affect all others.

While it is still unknown whether species will be able to adapt to new conditions, the marine food chain is already experiencing drastic changes – and plankton plays a crucial role across the board.

“If anything happens to the plankton, an immediate cascade effect will take place on the food chain,” Ivan Nagelkerken, a University of Adelaide’s biology professor, told DW.

Building blocks of life

Plankton are tiny aquatic organisms that drift through the sea, forming the basis of the marine food chain.

For plankton, both quantity and quality – in terms of nutrients – affect life up the food chain. Tiếp tục đọc “Plankton decline hits marine food chain”

E-Waste in East and South-East Asia Jumps 63% in Five Years

  • 2017•01•15     BONN

    The volume of discarded electronics in East and South-East Asia jumped almost two-thirds between 2010 and 2015, and e-waste generation is growing fast in both total volume and per capita measures, new UNU research shows.

    Driven by rising incomes and high demand for new gadgets and appliances, the average increase in e-waste across all 12 countries and areas analysed — Cambodia, China, Hong Kong, Indonesia, Japan, Malaysia, the Philippines, Singapore, South Korea, Taiwan, Province of China, Thailand and Vietnam — was 63% in the five years ending in 2015 and totalled 12.3 million tonnes, a weight 2.4 times that of the Great Pyramid of Giza.

    China alone more than doubled its generation of e-waste between 2010 and 2015 to 6.7 million tonnes, up 107%. Tiếp tục đọc “E-Waste in East and South-East Asia Jumps 63% in Five Years”

How environmental crime became an EU security priority for 2018-21

euractive_In May 2017, EU justice ministers decided that environmental crimes – including wildlife trafficking and waste crimes – would be one of the EU’s ten priorities for the fight against serious and organised crime during the 2018-21 policy cycle. Catherine Bearder evokes how this decision came to being.
