New sustainable way to create plastics from seaweed
By ISRAEL21c Staff
Israeli discovery overcomes need for fertile soil and fresh water in the creation of eco-friendly bioplastics by using saltwater seaweed.
Everyone knows plastic is bad for the environment. That’s why bioplastics – plastics made from renewable sources like plants or old waste – were invented. But these bioplastics can’t be created everywhere since the plants they use require fresh water, a scarce resource in many countries.
One such country is Israel, which does not have a surplus of fresh water. Other countries suffering from the same problem are China and India, whose size and resulting plastic consumption is very bad news for the planet.

By Paula Maccabee for Hadassah Magazine
Many of us dismiss Tu B’Shevat as a tree-planting holiday for children. And for those of us who live in the northern hemisphere, the holiday often falls during the depths of winter, making the “New Year of the Trees” seem misplaced. But Jewish learning and our natural environment require that we reclaim Tu B’Shevat—which this year begins the evening of January 20—as an important holiday to celebrate our relationship with Creation and take responsibility to protect the web of life on Earth.
6 Israeli Cleantech Companies Putting Sustainability at the Top of Their Agenda
By Klara Strube, NoCamels
For at least several decades, an overwhelming majority of climate scientists have agreed that global warming trends are occurring at a faster pace and are primarily driven by greenhouse gases emitted by human activities.
But the issue has become highly politicized, especially in the United States, even as new evidence emerges that urgent action is required. Hurricanes, floods, disease outbreaks are all set to worsen over the next decades if international efforts to cut greenhouse gas emissions are not fruitful. At the UN this week, 190 countries agreed to a universal, transparent set of rules on how nations can cut gas emissions but delayed more concrete, impactful decisions.
Hazon Perspective: Farm Bill Update
by Hannah Elovitz for Hazon
Our tradition teaches us to open up the corners of our harvest through pe’ah and to attune ourselves to the needs of land for rest and restoration through shmita. We at Hazon are therefore greatly relieved that the recently passed Farm Bill maintains food assistance access for those in need rather than imposing draconian work requirements and that it preserves programs that incentivize farmers to reduce erosion and increase soil carbon.
Novel gel propulsion to slash cost of communication satellites
By Abigail Klein Leichman for Israel21c
Cheaper, more environmentally friendly rocket-engine technology offers same level of performance and control as toxic ‘legacy’ fuel.
Watching a live event happening half a world away, or chatting with someone in another country, would not be possible without the hundreds of communications satellites orbiting Earth to relay telecommunications signals electromagnetically.
Propelling the largest of those satellites requires costly and highly toxic jet fuel, while launching smaller satellites requires other liquid fuels that could benefit from improvement.
