that the strain, which normally lives in mangrove wetlands, can also thrive on glycerol (an industrial byproduct), wastewater, and sewer sludge. Its ability to accumulate PHB when grown in such a variety of conditions makes it a promising candidate for transforming waste into bioplastics or into other useful products like fish food. A lofty load of bricks Around the world, treated sewage solids are still commonly burned or buried. But incinerating waste creates ash that, while reduced to a fraction of the starting volume, is still often dumped into landfills. Here too, researchers are actively investigating how to convert the solids and ash into useful products. Such recycling processes could yield a ton of bricks. Engineers at the Royal Melbourne Institute of Technology in Australia have focused on relieving the environmental problem of excavating clay soil for brick production, in part by exploring how to incorporate treated sewage solids, or biosolids, into fired bricks. If making poop bricks seems like an unusual application, consider that animal dung has been used to build homes and produce pottery for centuries. Piles of cow manure to be recycled by the Museo Della Merda pictured on March 28, 2017. When fired for 10 hours at nearly 2,000 degrees Fahrenheit, clay bricks with varying amounts of treated biosolids from Melbourne residents weren’t quite as strong as traditional counterparts. But they were lighter and better insulators — and otherwise indistinguishable in both appearance and odor. A 2019 paper from civil engineer Abbas Mohajerani and colleagues at the institute suggested that bricks made with at least 15% biosolids could still meet engineering requirements while theoretically recycling
Laboratory and a scientist at its host institution, Brookhaven National Laboratory in New York. In space, every ounce of cargo — including heavy but necessary water — is precious. “If you have it anyway, can you use it for something?” he said. “In theory, it should work.” A plastic proposal Now try to reimagine wastewater treatment plants on Earth doubling as multipurpose resource recovery facilities. As an alternative to plastics made from fossil fuels, for example, researchers are making headway in producing safe and biodegradable bioplastics from existing waste streams. Creating planet-friendly bottles, containers, and other bioplastic products from what we leave behind is still a work in progress, said Zeynep Cetecioglu Gurol, an associate professor of industrial biotechnology at the KTH Royal Institute of Technology in Stockholm, Sweden. Even so, developing an efficient and affordable method for recovering new products from wastewater could help offset the money, time, and effort spent by treatment plants to meet pollution limits in discharged water. “I think it’s a win-win,” she said. What really happens to the plastic you throw out Many wastewater treatment plants are already using a microbe-dependent process called anaerobic digestion to create biomethane gas, a sustainable fuel alternative, from sewage. Cetecioglu Gurol and other researchers have found that organic compounds created during that biogas production process provide a good source of carbon for creating bioplastics. The goal now is to ramp up production efficiency. “We are still in the baby steps,” she said. One type of bioplastic called polyhydroxybutyrate, or PHB, is naturally produced by some bacterial species as they feed on organic material. Tests suggest that PHB can replace a variety of petroleum-based plastics and that unlike them, it biodegrades rapidly under normal environmental conditions. A bacterial strain called Zobellella denitrificans ZD1 has attracted the attention of researchers like Kung-Hui Chu, a professor of environmental, water resources and coastal engineering at Texas A&M University. Chu and colleagues have found
from Mars, the space agency had initially looked at producing fuel from resources on the red planet, Sepka wrote in an email. But NASA is now considering whether repurposing waste from the crew itself could help the astronauts, well, blast off. As for protecting crewmembers from dangerously high radiation levels in outer space during an extended voyage, scientists have suggested that the density of molecules in wastewater could offer a solution. One multi-purpose NASA proposal, called “Water Walls Architecture,” envisions a space capsule lined with multiple compartments of water as well as sterilized waste deployed as radiation shielding. The primary ingredient of both urine and feces is water, and the tightly packed atoms of hydrogen and oxygen in water offer a higher density of cosmic ray-blocking nuclei than metals do. Think of it as a doo-doo deflector. A water-based shield could work well to block radiation particles, said Peter Guida, the liaison biologist for NASA’s National Space Radiation
