And they know it delivers more nicotine than the cigarettes it's supposed to replace. But the social aspects of vaping drives young people to use Juul and other e-cigarettes, according to nearly two-thirds of teens and young adults in a new study. Less than 5% say the availability of fruity flavors drives use of e-cigarettes by members of their generation, and only 10% say addiction does.

The Government is actively exploring sustainable and innovative approaches to expand the city’s land resources. One viable source of land supply is rock cavern development.

The relocation of suitable existing government facilities to caverns can release above-ground sites for housing and other beneficial uses. This would reduce the amount of land occupied by them, as well as relocate facilities which do not need to be above-ground and are incompatible with the surrounding environment and land uses nearby.

Mountain move

Sha Tin Sewage Treatment Works is one such facility. It will be relocated to caverns in Nui Po Shan of A Kung Kok to release the existing site of about 28 hectares for housing and other uses that will enhance Hong Kong’s living quality and bring extended benefits to the community and environment of Sha Tin.

Drainage Services Department Sewerage Projects Division Engineer Brian Chan said that moving the sewage treatment plant to caverns minimises any adverse impact on the environment and community.

“The whole sewage treatment works will be put inside the cavern and the cavern will serve as a natural barrier fully enclosing the sewage treatment works. With the implementation of an effective odour management system, the odour impact to the community will be minimised.”

Mr Chan added that moving the existing plant, which has been in operation for more than 35 years, provides an opportunity to formulate a long-term strategy for the ageing facility.

High-tech solutions

The relocated Sha Tin Sewage Treatment Works will consist of several caverns.

A successful local example of accommodating facilities in rock caverns is Stanley Sewage Treatment Works on which the layout for the Sha Tin treatment plant is based.

To reduce the required cavern space and shorten the construction period, advanced sewage and sludge treatment technologies will be used.

Water recycling is a multi-stage process in wastewater treatment plants.

Mr Chan explained that moving bed biofilm reactors will be used in the secondary treatment process at the relocated Sha Tin plant as they require less space than the traditional wastewater treatment.

“Compared to the conventional method, there will be some biofilm carriers inside the reactor and this biofilm carrier will enlarge the surface area for the biological treatment and therefore, the overall size will be reduced. In terms of the sewage treatment process, there will be about a 20% reduction in the areas.”

Sha Tin Sewage Treatment Works serves a population of about 630,000 in Sha Tin and Ma On Shan, which produce 250,000 cubic metres (m3) of sewage daily. After the relocation, the facility will be able to handle 340,000 m3 of sewage per day.

The first phase of works to relocate Sha Tin Sewage Treatment Works to caverns began in February. The Drainage Services Department hopes to start the second phase from the end of next year to early 2021 with the excavation of the caverns. The department plans to move the whole sewage plant in five stages. The project is expected to be completed by 2031.

Members of the public can visit the department's website for more details about the project and its latest developments.

The Airport Authority expanded the scope of its food waste recycling programme in 2011 to cover Hong Kong International Airport business partners, including restaurants and lounges operating in terminal buildings, as well as airline catering companies, hotels and cargo terminals.

In 2017-18, over 2,000 tonnes of food waste from 17 airport business partners were collected for recycling.

Rainie Ho, the supervisor of one participating restaurant, said staff make every effort to collect food waste on a constant basis.

“We have three bins of recycled food waste, including eggs, toast, bread, chicken, meat, pork bones, tea and coffee every day.”

Ms Ho gave kudos to the Airport Authority for making the process simple.

“The Airport Authority provides us with garbage bags every month. We explain to our staff that the red bags are for food waste, while the black ones are for general rubbish. This makes it easier for them to remember and handle.”

Airport Authority Assistant General Manager (Sustainability) Mike Kilburn is the facilitator of the food waste recycling programme. He hoped to encourage more business partners to join by making the scheme as trouble-free as possible.

“This is an example of an easy, useful and free programme because the contractor comes to collect from each company and the contractor provides a clean rubbish bin for the food waste, they take the food waste away, they wash the bin and then they bring it back clean.

“And it is useful because the food waste is not just sent to the landfill, but it is turned into fish meal so it goes back into the food chain because the fish meal is fed to the fish and the people can eat the fish, so it is a very complete system.”

Surplus food collection

In addition to food waste recycling, the authority promotes the Food Rescue Programme in co-operation with a local non-governmental organisation called Food Angel.

In 2013, the authority helped Food Angel to purchase a refrigerated truck and covered the cost of collecting surplus food from business partners on the airport island.

By 2014, a central storage room was set up in the terminal building to collect even more surplus food from catering outlets.

By proving it can reduce its environmental impact by working closely with the entire airport community, the authority was recognised at the 2018 Hong Kong Awards for Environmental Excellence where it won the Gold Award for the Public & Community Services Sector.

Future prep

In 2018, the authority launched a voluntary municipal solid waste charging pilot scheme to achieve waste reduction.

It has assisted more than 200 tenants with measuring their waste generation and calculating what it would cost to dump it in the future.

Another participating restaurant manager Alfred Lau explained that the pilot scheme helps restaurants gear up for the polluter-pays principle.

“A mock monthly invoice was issued to us, showing the quantity of waste disposed and the estimated disposal charge. Now we understand that by reducing our waste, we will pay less in the end.”

Mr Lau believes the pilot scheme encourages eateries to alter their disposal behaviour by recycling as much food waste as possible.

“Our disposed waste amount fell sharply once we learnt useful ways to recycle. Our restaurant is located in the restricted area of the airport where drinks are not allowed to be brought inside. So many passengers buy bottled drinks and create a large amount of plastic waste. Just by recycling plastic bottles, our waste decreased significantly.”

The authority said it is proud to be the driving force behind waste reduction.

“We make it easy for them because we do all the organisation, we make it useful because they can help them to prepare, and it is free for them to join the programme. This is very important for us because as the Airport Authority, our job is to create a concept that other people can follow and if you address those three criteria, you make it very hard for them to say no to you. We take away their reasons to say no, so it is easy for them to join our scheme,” said Mr Kilburn.

The Hong Kong Awards for Environmental Excellence is led by the Environmental Campaign Committee alongside the Environmental Protection Department and in conjunction with nine organisations. The objective is to reduce Hong Kong’s environmental impact by promoting environmental management.

The Airport Authority’s current target is to reduce, recycle and recover 50% of all its waste by 2021.

Chief Justice Patience Roggensack faced backlash for her comment, with some people calling it "elitist" to separate meatpackers from "regular folks."

Senator Dianne Feinstein (D., Calif.) on Thursday attacked former Joe Biden staffer Tara Reade, who alleges she was sexually assaulted by Biden in the spring of 1993.Feinstein said the allegations were “totally different” than those against Supreme Court justice Brett Kavanaugh.“Kavanaugh was under the harshest inspection that we give people over a substantial period of time,” Feinstein told CNN on Thursday. “And I don't know this person at all [Reade] who has made the allegations [against Biden]. She came out of nowhere. Where has she been all these years? He was vice president.”Christine Blasey Ford, Kavanaugh's accuser, claimed that Kavanaugh sexually assaulted her in 1982, an allegation that was known by Feinstein's office before it was publicly reported in September 2018. Feinstein later denied that she or anyone in her office had withheld Ford's allegation for political purposes or had leaked the allegation to the press.Reade, meanwhile, called on Biden to drop out of the presidential race in an interview with Megyn Kelly released Thursday.“I want to say: You were there, Joe Biden. Please, step forward and be held accountable. You should not be running on character for the president of the United States,” Reade said.

The U.S. Navy is in “rough waters” and suffering from leadership failures, the diplomat tapped to be the next Navy secretary told a Senate committee Thursday. Kenneth J.

Braithwaite said that Navy culture has been tarnished and trust in the service's leaders has broken down.

As businesses slowly reopen, experts warn that social distancing may need to be dialed back up: ‘It’s not an on-off switch’ * Coronavirus – latest US updates * Coronavirus – latest global updatesSome California businesses on Friday began opening their doors for business – at least partially.As states and counties across the nation contend with pressure to lift the stay-at-home measures that have destroyed local economies, California is taking an especially cautious approach, walking a fine line between political and economic pressure to reopen and the public health imperative to stop the spread of disease.Public health experts told the Guardian that while no US state was equipped with enough coronavirus testing and surveillance to feel fully confident reopening, California’s slow, piecemeal recovery plan – though far from perfect – seemed like the least risky option. The planSeven weeks after the governor, Gavin Newsom, ordered his 40 million constituents to shelter in place and all non-essential businesses to close, California on Friday entered phase two of its grand reopening plan.Some retail stores, including bookshops, florists, music stores, clothing and sporting goods retailers, can reopen if they organize curbside pickup. Some manufacturing and logistics in the retail supply chain can restart as well, as long as they follow safety and hygiene protocols. And local authorities are allowed to ease regulations further than the state guidelines if they meet certain testing and sanitation requirements.Phase three of the plan – potentially months away – could see salons, gyms, movie theaters and in-person church services resume. Phase four would end all restrictions. The timingFriday’s reopenings come as California has avoided the surge of infections states like New York have seen. And although California has seen more than 61,000 cases and 2,500 deaths, its hospitals have not been overwhelmed.Last week, state officials reported the first week-over-week decline in Covid-19 deaths.The new guidelines also follow small but sustained protests across the state to demand a relaxation of regulations to revive the state’s crippled economy, and some rural counties have partially reopened in defiance of the lockdown measures. The caveatsHowever, California still hasn’t seen the two weeks of declining cases that the White House suggested as a criterion for easing restrictions and that several European countries have used as a benchmark.The state also lacks the robust testing and tracking systems that countries such as Germany and South Korea have used.The state has ramped up its ability to administer and process tests, although for now, its rate of 29,414 tests a day is below the figure required by some analyses.Authorities are working to put a robust contact tracing effort in place to make sure those who test positive get the care they need and are able to isolate themselves until they recover. Although some counties and communities have spearheaded community-wide testing and tracing programs, overall, the state isn’t at the point where its system is as widespread or efficient as a country like Germany’s.Experts say California should also have a system in place to make sure vulnerable, unhoused populations have access to shelter and medical care – to prevent infection flare-ups in homeless shelters and encampments. Progress on those measures heavily varies county by county.And ideally, there would be a treatment or a vaccine before reopening, said Dr Richard Jackson, a professor emeritus at the UCLA Fielding School of Public Health and the former head of the California department of public health. While we await a cure, Jackson cautioned, “no one should feel completely safe as we remove restrictions.” The trade-offsCalifornia’s reopening strategy stands in sharp contrast to the approach of states like Georgia, which suddenly allowed gyms, barber shops, hair salons, tattoo parlors and bowling alleys to welcome customers last week.“What certain places have done, where they’ve just thrown open the doors and said, ‘OK, we don’t have to keep our distance any more,’ is a colossal mistake,” Jackson said. Reopening businesses that put lots of people into close contact and speed the spread of disease will reverse the success of shelter-in-place rules, he noted, and overwhelm hospitals as cases surge. “Doing it very cautiously and carefully does make sense at this point in time,” he said.“I get that governors have to balance the public health goals with the economic goals,” said Dr Robert Tsai, surgeon and health policy researcher at Brigham and Women’s hospital in Boston and the Harvard TH Chan School of Public Health. “But this stage of the pandemic is really all about trade-offs,” he noted. The weeks aheadIn the coming weeks, state and local leaders will have to watch closely and prepare to dial the distancing back up if the number of cases surges, said Tsai.“Social distancing isn’t an on-off switch. What it needs to be is a dial, which can be turned up or down depending on what the data show on the ground in terms of how the Covid-19 epidemic is progressing.“Reopening is going to be a very complicated process, and it should be complicated,” he added. “Because this is about making sure that people don’t end up in the hospital or dying.”That California’s plan allows for counties to maintain stricter distancing guidelines or ease up measures could be both a strength and a liability.The flexibility has allowed hotspots like the Bay Area and Los Angeles to take a more cautious approach, but it has also already caused confusion. In San Diego, where curbside shopping has already begun, business owners were unsure what, if anything, would change on Friday. In Bakersfield, restaurants allowed patrons to dine in on Monday and Tuesday, in defiance of the state’s guidelines.A hodgepodge reopening could cause surges in cases; Californians who travel between more lax and more strict counties could spread infections. Moreover, a rush to reopen fast in some areas could be counterproductive to economic recovery, said Alessandro Rebucci, an economist at the Johns Hopkins Carey School of Business.“If you reopen when the pandemic is still out there, people and businesses will not just go back to normal,” Rebucci noted. Based on research from China, it seems clear that fear of contracting the illness will keep businesses owners and patrons home until they feel it’s safe enough, he said.
