Recycling biosolids to make sustainable bricks

How can you recycle the world’s stockpiles of treated sewage sludge and boost sustainability in the construction industry, all at the same time? Turn those biosolids into bricks.

Biosolids are a by-product of the wastewater treatment process that can be used as fertiliser, in land rehabilitation or as a construction material.

Around 30% of the world’s biosolids are stockpiled or sent to landfill, using up valuable land and potentially emitting greenhouse gases, creating an environmental challenge.

Now a team at RMIT University in Melbourne, Australia, has demonstrated that fired-clay bricks incorporating biosolids could be a sustainable solution for both the wastewater treatment and brickmaking industries.

Published this month in the journal Buildings, the research showed how making biosolids bricks only required around half the energy of conventional bricks.

As well as being cheaper to produce, the biosolids bricks also had a lower thermal conductivity, transferring less heat to potentially give buildings higher environmental performance.

The EU produces over 9 million tonnes of biosolids a year, while the United States produces about 7.1 million tonnes. In Australia, 327,000 tonnes of biosolids are produced annually.

The study found there was a significant opportunity to create a new beneficial reuse market - bricks.

Clearwater's plan to turn wastewater to drinking water is on hold

After 10 years of study and a $6.2 million investment, Clearwater has the design and permits to break ground. But construction on the cutting edge plant is stalled due to costs.

CLEARWATER — Tampa Bay’s third largest city was supposed to be the first in the state to treat wastewater beyond drinking standards and inject it into the Floridan aquifer so it would make its way back into the drinking supply.

The endeavor began in 2009 with a feasibility study, then a pilot facility that tested the technology for a year. By 2016 Clearwater was the first in Florida to design a full-scale groundwater replenishment facility, modeling it on a similar pioneering plant that launched in Orange County, Calif, in 2008.

Now after 10 years and an investment of $6.2 million, Clearwater has the final design and all permits needed to break ground, still ahead of any other city in the state.

But higher-than-expected building and operation costs have delayed construction indefinitely, making Clearwater the first to be stalled by the expense and unfamiliar terrain of what could be the next frontier of drinking water in Florida. Just building the plant is now expected to cost nearly $7 million more than what was estimated three years ago.

Gov. DeSantis announces sweeping fixes meant to clean up Florida's water woes

Two days after he took office, Gov. Ron DeSantis unveiled sweeping measures to clean up Florida’s troubled waters Thursday, including spending $2.5 billion and launching more aggressive policies to address algae choking Lake Okeechobee and polluting the state’s coasts.

The newly minted governor, who angered environmentalists on the campaign trail by dismissing climate change as a significant threat, also promised to establish a resiliency office to address looming dangers.

“The people of Florida wanted to see action and this was action that was requested regardless of your party,” DeSantis said in a morning briefing at a Florida Gulf Coast University field station in Bonita Springs, north of Naples. “This is something that can unite all Floridians.”

DeSantis also ordered construction sped up on a 17,000-acre Everglades reservoir in farm fields south of the lake and said he would work with federal officials to end polluted discharges.

“I’d like to see no discharges,” he said. “We’re working with the White House and as difficult as it is, working with the Army Corps [of Engineers] to mitigate that.”

The new governor also promised to appoint a chief science officer so “we’re doing sound science making sure we’re getting ahead of the curve on these issues.”

Hurricane preparedness casualty of federal government shutdown

Weather models are not being updated and training sessions might be canceled during the budget standoff

The U.S. government’s partial shutdown is in its third week, and the pinch of the protracted standoff over funding for a wall along the country’s border with Mexico is starting to be felt—not only by workers missing paychecks, but also in terms of important science that is not getting done.

About 800,000 workers have either been furloughed or, if their jobs are deemed essential to protecting lives and property, are working without pay across dozens of shuttered agencies and departments. These include several that do significant scientific work such as the Environmental Protection Agency, the Interior Department, NASA and the National Oceanic and Atmospheric Administration (NOAA)—the parent agency of the National Weather Service. Although day-to-day forecasting operations continue at the NWS, key improvements to weather models have been put on pause. Data needed for research projects may be inaccessible; and if the shutdown continues much longer, preparedness training will be canceled for emergency managers in coastal communities looking warily ahead to the coming hurricane season after the devastating storms of recent years.

Eric Blake, a forecaster with the NWS’s National Hurricane Center in Miami spoke with Scientific American about the shutdown’s impact on the NWS and its employees (in his capacity as the National Weather Service Employees Organization union steward at the center).

Federal government spending $100 million to study desalination

The Trump administration is hoping to reinvigorate a technology long dismissed as too expensive or energy-intensive to help solve a water crisis that has seen drought grip swaths of the American West, sparking deadly wildfires and legal battles over supply.

The Energy Department last month declared that it's spending $100 million over the next five years to create a research and development hub on desalination, a process that converts seawater and brackish inland water into freshwater.

Announced roughly five years after Congress appropriated the funds under the Obama administration, the planned hub comes as once-periodic water shortages have become perennial, if not ever-present, in American communities, forcing policymakers to rethink how residents get freshwater – and reconsider technologies they'd once shelved.

The investment is widely seen in the research field as a moonshot effort, the best attempt yet to jump-start the kind of advancements that would make the elusive process energy-efficient and cost-effective and make a resource out of vast unusable deposits like the saltwater that covers two-thirds of the earth's surface.

"The significance can't be understated. Something like this has been a long time coming," says Jonathan Brant, associate professor of environmental engineering at the University of Wyoming.

"We're faced with a real water crisis, and the main solution to that is going to be able to tap – in an environmentally sustainable and economically sustainable way – saline water sources."

Desalination is costly and enormously energy intensive: Israel and Australia – two of the driest nations on Earth – are by far the world leaders in desalination, largely by necessity. While Israel draws more than half of its water from desalination plants – and more than 85 percent of its municipal water overall is reused – desalination plants in the U.S. provide less than 0.002 percent of the water consum

Senate panel briefed on septic tanks’ contribution to algae outbreak

Septic tanks are one of the primary triggers for toxic algae blooms throughout the state, the Senate Agriculture, Environment and General Government Appropriations Subcommittee was told Wednesday.

A presentation was given by Dr. Brian Lapointe, who has worked as a research professor at Florida Atlantic University and has studied water quality in the state for decades.

He has previously produced work, funded by the Florida Chamber of Commerce, showing that septic tanks are a large contributor to the pollution that allows algae blooms to spawn in Florida’s waterways.

“I personally consider this the most important and urgent issue facing our state,” Lapointe said.

That runs counter, however, to many environmental groups who put the blame mostly on phosphorus from fertilizer runoff from sugar farms.

Pinellas County asks court's help to deal with Redington Long Pier

REDINGTON SHORES — County officials are asking the Pinellas circuit court to order the owner of the historic Redington Long Pier to repair, replace or remove the structure as soon as possible

The request for an injunction was filed Dec. 26 by Assistant County Attorney Jared D. Kahn against JERMC, Ltd., the pier’s owner.

JERMC is headed by longtime pier owner Tony Antonious.

A number of allegations relating to the pier’s unsafe condition are made in the county’s request. The pier’s closing by a county judge in 2006 “until repairs are made to the pier that would render it safe for public use” is noted.

Despite that order, Kahn wrote, the current situation is that “the pier does not meet the Florida Building Code requirements for live and wind loads and is in a precarious state of structural functionality. As late as December of 2018, storm and high winds have caused the pier to take substantial damage, including causing portions of the Pier to collapse into the waters below.”

Jan. 8th public meeting set for Roosevelt Stormwater Facility improvements

Pinellas County will hold a Neighborhood Information Meeting regarding planned improvements at the Roosevelt Stormwater Facility near 43rd Street North and Lake Boulevard in Pinellas Park.

The meeting is set for Tuesday, Jan. 8, from 6–8 p.m. at St. Petersburg College EpiCenter, Rooms 1-451, 453 and 455, 13805 58th St. N., Clearwater.

County staff and consultant representatives will share information and answer questions about the project, which aims to improve water quality by reducing pollutants in the stormwater runoff that flows into Roosevelt Creek and eventually Tampa Bay. Citizens are invited to review engineering plans at this link and to provide feedback at the meeting.

In a related project, the County is in the design phase of planned improvements to Roosevelt Creek Channel 5. The existing salinity weir (concrete wall) will be removed to create a more natural connection to Tampa Bay and promote the passage of aquatic organisms and improve flood flows. This project will also include the removal of accumulated sediment in Channel 5 from Executive Drive north to the weir, stabilization of the banks where necessary and habitat restoration adjacent to the weir.

Residents who cannot attend the meeting and have comments or questions are invited to contact the project team at 727-464-8900 or SWProjects@Pinellascounty.org.
