Sludge Eaters.

first_img Photo:UGA CAES Earthworms eat and convert sludge into a more environmentally safe product. Earthworms have a healthy appetite. If you get enough of themtogether and don’t disturb them, scientists say they can safely,quietly dispose of many forms of waste.Vermiculture is a composting system that uses worms to processorganic waste, said Sid Thompson, a professor of engineering withthe University of Georgia College of Agricultural and EnvironmentalSciences.The process could be a viable alternative, he said, for currentwaste-management practices that continue to grow more expensiveand impractical as the world’s population expands.Goes in Bad, Comes Out Good The earthworms don’t have to be trained for vermiculture or doanything unusual. They just do what comes naturally: eat. As theworms eat organic materials, such as sludge from wastewater treatmentplants, they excrete it as castings. Worm castings, which look much like freeze-dried coffee crystals,make good fertilizer for plants. They also improve the waterand nutrient-holding capacity of the soil. “Castings are more microbially active,” Thompson said.”The nutrients are more available to plants.”The worms get rid of the harmful waste and in return provide amuch nicer product that’s not as smelly. Not only are the castingseasy on the environment, they can catch a good price as well.Castings are advertised on the Internet for as much as $4.25 perpound.Cities around the world are looking to vermiculture to combatwaste problems, Thompson said. Vermiculture in India, one of themost heavily populated places in the world, gets rid of as muchas 30 tons of waste a day.Thompson said vermiculture could work for Georgia, too. To beviable on a large scale, though, it must be proven economicallyfeasible.Worms take to sludge like mice to cheese. In fact, one worm caneat its weight in sludge every day. One pound of worms can eatand process one pound of sludge.However, a large land area would be needed for the worms to processlarge amounts of sludge, said Jason Governo, a graduate studentworking closely with Thompson’s research.A Pound of Worms Can Tell You More Most vermiculture research uses only one or two worms in smalllaboratory settings. Thompson and Governo are using pounds ofworms in their research.Their studies show that only 3 to 4 inches of sludge can be placedonto the worms at any one time, Governo said. With such a thinlayer, it would take too much land and wouldn’t be economicallyfeasible for Georgia.But Thompson said the land problem could be solved simply. Heproposes placing the sludge and the worms in trays and then stackingthose trays in a tall structure. “There are ways this canbe done for waste in the state,” he said.Thompson said worms can convert a range of organic material, aslong as the material is presented in an acceptable form.Georgia is one of the leading poultry producers in the world.It’s also one of the leading producers of manure from layer hens,the birds that lay eggs. Large quantities of this manure can strainthe environment.Worms, Thompson said, could convert layer manure into a more environmentallyacceptable product. However, the natural high salt and ammoniacontent found in layer manure dries up and kills the worms.Vermiculture could be the answer to the large volume of chickenlitter produced in Georgia, he said. Scientists just have to findthe right way to present it to the worms.last_img read more

Novel’s alleged attackers should be acquitted to restart investigation: Former KPK chief

first_imgTopics : Other former KPK leaders and Novel’s legal team members had urged the KPK to act upon the light sentence sought against the defendants, arguing that the attack on Novel was an attack on the national corruption eradication agenda as well. “If I were the judge, I would use my judge reasoning in addition to my legal reasoning and intuition,” he continued.If the judge were to acquit the defendants of all charges, Busyro suggested that President Joko “Jokowi” Widodo form an independent fact-finding team to reopen the new investigation instead of handing it over to the police again.State prosecutors had previously demanded a one-year prison sentence against the defendants, police personnel Chief Brig. Ronny Bugis and Brig. Rahmat Kadir Mahulette. The defendants allegedly attacked Novel with sulfuric acid, resulting in serious damage to Novel’s eyes.The light sentence demands had sparked public outcry questioning the prosecutors’ arguments that the defendants “accidentally” threw the acid into Novel’s face in April 2017.Read also: Baffled by light sentences sought for Novel Baswedan’s attackers, netizens turn to humorActivists and members of the public also raised suspicions that the two policemen were merely scapegoated, with the mastermind still at large.Novel had tweeted through his Twitter account, @nazaqistha, that the defendants should be released “rather than making things up”, expressing his disbelief that the accused were the real culprits.

He was later freed of all charges by the Bantul District Court in 1997 due to a lack of evidence.“The real culprit will not be revealed unless the judges free the defendants with their conscience,” Busyro, who led the antigraft agency from 2011 to 2015, said. Former Corruption Eradication Commission (KPK) chairman Busyro Muqoddas expressed support for the judges at the North Jakarta District Court to free the alleged attackers of graft buster Novel Baswedan in order to give room for a new investigation.“Hopefully the panel of judges will acquit [the defendants] so a new investigation can be carried out,” he said in a virtual discussion on Novel’s case held by Indonesia Corruption Watch (ICW) on Friday.Busyro said the new inquisition would hopefully reveal the real culprits and masterminds behind the case. He cited the murder case of a journalist of Yogyakarta local daily newspaper Bernas during the New Order era.last_img read more

UEFA president counts on full football stadiums for Euro 2021

first_img Loading… Euro 2020 football competition, which has been postponed to 2021 because of the coronavirus outbreak, should be able to take place with an audience, and without any change to the format in 12 cities, according to UEFA president Aleksander Ceferin. “We will have spectators in the stadiums,” Ceferin said in an interview with AFP on Thursday, adding that what people think is strange today might no longer be strange in December or January. “We still have time to think about it,” Ceferin said. “For the time being, we are keeping the same format and we hope and believe that we will have spectators in the stadiums.” Euro 2020 should have taken place in June and July of this year, but the coronavirus pandemic forced UEFA, the governing body of European football, to postpone its scheduled competition in 12 cities in 12 countries for a year. This postponement allowed the switch to club competitions, the Champions League, Europa League, and major national championships, to take advantage of the dates released to go ahead behind closed doors in late spring and summer, after several weeks of paralysis in European football in the face of the spread of the disease. read also:UEFA approves 210 bottles of water per team, cancels shirt swaps Ceferin assured that he did not entertain the question of playing behind closed doors. However, apart from France, where a maximum capacity of 5,000 people is allowed in the stadiums, most of the major European football countries are currently organising matches without an audience.

The man had not completed the designated form after returning from the red zone, and failed to go into mandatory quarantine. “The man was immediately arrested and placed in quarantine,” Haaltert mayor Veerle Baeyens said on Thursday, being satisfied with the police handling. “The man has been tested [for coronavirus] and we will know the results on Friday. Depending on the results, it may be necessary to take measures in his company,” she added. The company has also been contacted and informed. The man now faces a fine for violating Belgian measures to fight the spread of Covid-19. FacebookTwitterWhatsAppEmail分享 last_img read more
