Hong Kong environment professionals call for accreditation scheme to improve impact assessment quality

With more complex development projects, institute says improved accountability is also needed

A professionals institute has called for the creation of a government-recognised chartership scheme that would accredit qualified environmental impact assessors and raise industry standards.

It comes amid increasing demand for environmental impact assessment studies as more and more complex development projects are proposed for the city.

The Institute of Qualified Environmental Professionals (HKIQEP) said the scheme would be similar to those offered by professional institutes for local surveyors, architects or engineers.

“There are many ways to substantiate your technical expertise, but under the current system there is no recognition for the environmental discipline,” institute vice-chair Freeman Cheung Chun-ming, a senior environmental manager at engineering consultancy Aecom, said.

“The purpose will be to upgrade the professional recognition of environmental professionals… to make sure members are well qualified and have a good ethics and quality.”

Cheung said the HKIQEP would be empowered by ordinance to issue Qualified Environmental Professional credentials to members who meet the experience requirements and pass a trade test and interview. Project proponents could then request to hire only those who have the relevant qualification.

He said discussions had been held with lawmakers and the government on the proposal.

The HKIQEP is made up of a number of related institutions, including the staff union for the government’s environmental protection officers.

The quality of environmental impact assessments, has come under scrutiny in recent years with multiple judicial reviews lodged against different projects, including the most recent regarding the airport’s third runway.

Over 200 environmental impact assessment studies have been approved since the ordinance came into effect in 1998.

Clara U Kam-wa, who chairs the Institute of Environmental Impact Assessment welcomed the proposed scheme.

“Accreditation doesn’t necessarily mean things will be better, but with a qualified professional, environmental consultants would be held accountable for their work,” she said.

Ecologist Dr Billy Hau Chi-hang, a member of the government Advisory Council on the Environment also commended the idea, but hoped it would improve quality control in studies.

“It’s better than nothing,” he said, questioninghow the qualification would cover such a varied field of expertise, including air and water quality, noise or ecology.

Next frontier in recycling: food

As Americans generate unprecedented volumes of garbage, much of it food and yard scraps, large-scale composting is slowly gaining traction.

http://www.csmonitor.com/Business/new-economy/2017/0101/Next-frontier-in-recycling-food

At the end of a long, rural road 22 miles east of Washington, Prince George’s County’s composting facility is chewing through thousands of tons of leaves and tree branches that are trucked in daily from across the region.

In the past three years, the county has added a new ingredient to its compost: food scraps. Pizza boxes, coffee grinds, and vegetable peels from 25 commercial customers lie in neatly piled rows on this 55-acre, open-air site. They are working through a natural digestion process boosted by hungry microorganisms and freely available oxygen from the air.

On a frigid winter day, fresh from the decomposing routine, a rich-brown, almost clay-like humus was still steaming.

“We can’t grow fast enough,” says Adam Ortiz, director the Prince George’s County Department of the Environment. The facility will double its food-processing capacity next year to accommodate 30 more customers on the waiting list, including a university and an airport, and it could grow 10-fold in the long run. “We knew that there would be interest, but we didn’t realize the amount.”

This Prince George’s facility offers a peek into the next frontier of recycling. Food and yard trimmings account for a bigger share of America’s trash than anything else – about 28 percent – slightly ahead of paper and cardboard and twice the level of plastic. And while the US recycles more than half of its yard trimmings, food composting is in its early and costly stages.

But a dearth of landfill space, friendly public policies, social pressures, and other factors are beginning to spur industrial-scale efforts to turn trashed food into something useful. For example: California, Connecticut, Massachusetts, Vermont, and Rhode Island have banned some large food producers and other large businesses, such as convention centers and supermarkets, from throwing away food, making composting a popular alternative.

Cities including San Francisco, where composting food waste has been mandatory since 2009; New York City; Austin, Texas; Cambridge, Mass.; and Milwaukee are piloting residential food composting programs. In all, more than 180 communities now collect residential food scraps up from only a handful a decade ago, according to a 2014 report from the Institute for Local Self-Reliance.

From an environmental point of view, composting is a much better option than the alternative: overstuffed landfills, often located in poor neighborhoods, where rotting food spews greenhouse gases into the atmosphere. The third largest source of United States emissions of methane, a greenhouse gas significantly more potent than carbon dioxide, are landfills, according to the US Environmental Protection Agency. If diverted from trash, compost produced from leaves, branches, and food scraps can help fertilize soil on gardens, farms, gold courses, and elsewhere.

But barriers remain to making food composting widespread.

The chicken-and-egg problem

One challenge is the chicken-and-egg problem, says Samantha MacBride, Director of Research and Operations at New York City’s Department of Sanitation. “Firms are not going to invest in plants unless there’s a guaranteed supply, but cities won’t start [composting] until they know there’s a processor” to handle the waste.

Composting food – which, if not treated properly, attracts rodents and stinks up the neighborhood – is expensive and complicated.

“It’s not like it’s a massively profitable enterprise that a lot of people are jumping into,” points out Eric Myers, Director of Organic Recycling at Houston-based Waste Management, which runs about 40 organics recycling facilities around the country.

His company also turns food waste into a sludge that municipal wastewater treatment plants, huge energy hogs, use to create electricity by harvesting the the methane that naturally comes from rotting food. This is another popular solution for discarded food.

Making compost or energy out of food scraps is still more expensive than sending trash to landfill in many regions, even in Prince George’s County. Mr. Ortiz says his composting facility is operating at a loss now, though he hopes to turn a small profit from selling compost as the facility grows.

In some places sending trash to landfill costs as little as $25 a ton, according to Mr. Myers, compared with a national average $36 a ton for composting. “That makes it a lot harder to invest time and resources” in recycling food, he says.

Cities look to flip the script

But in cities like Cambridge, which piloted in 2014 a small food recycling program that now includes 5,200 households, composting food is cheaper than trash disposal, which in New England can run up to $85 per ton.

The expensive part is hauling, says Michael Orr, recycling director for Cambridge. If enough residents divert their food from trash – right now half of the pilot households send their food scraps for composting – the city could use freed trash trucks to collect food scraps.

Milwaukee also is trying to make the composting numbers work. Its one-month-old, 500-household food-composting pilot is the latest attempt in a multiyear effort to divert recyclables from trash to meet the city’s goal of reducing garbage by 40 percent by 2020.

The city is struggling to meet the goal, in part because Milwaukee charges a flat fee for trash collection, says the city’s sanitation services manager, Rick Meyers. “If you’re paying a flat fee … there’s no incentive for people to think more critically about the materials they generate and discard,” he says. The city council has been reluctant to approve a fee structure that ties the trash cost to the amount that residents generate, though, arguing that it would burden the large population of low-income residents and exacerbate the city’s illegal dumping problem.

Despite the challenges facing food recycling, Ms. MacBride urges patience. Food composting today is where curbside recycling of glass and paper was in the 1970s when it was first introduced, she points out. “Recycling programs didn’t start up overnight; they slowly ramped up,” she says. “Give it time is really the takeaway.”
