This past week I visited 2 of the 4 SWM facilities within my own county. LCSWMA (Lancaster County Solid Waste Management Authority) handles landfilling, recycling and waste-to-energy services for two PA counties (about 800,000 people in 2014). This past week I visited the Frey Farm Landfill as well as their Waste-to-Energy Plant.
My goal was to better understand how these kinds of facilities are operated, the pros and cons of certain approaches, and also see if there was anything I could learn from how these sites are managed that can help me better understand the challenges faced in India. I’ll describe my experiences at both sites in separate posts and then explore what might and might not work for similar facilities in India.
The Frey Farm Landfill
The Frey Farm Landfill is located about 20 minutes from downtown Lancaster in scenic farmland. As I approached the landfill I saw only a large green hill in the distance. The stereotypical images we have in our minds of what a landfill is “supposed” to look like didn’t apply here. I parked at the visitors center and waited for my guide. Another unexpected thing I noticed. There was almost zero foul odor in the air. Frankly, I wouldn’t have complained about it if there had been, since, again, I was expecting it. But on that sunny, clear day, I could have been standing in any rural neighborhood in Lancaster.
My guide Allison was kind enough to take me around (I was the only person signed up for the tour that day). We drove around the massive landfill as she explained the LCSWMA philosophy, history, environmental and safety practices, as well as what they call their “Integrated System” which allows them to provide energy, divert waste away from the landfill, and keep toxic pollutants out of the water, air and soil. Things I was impressed with:
- Waste-to-Energy solutions: Methane from the decomposition of waste at the landfill is siphoned off to a combustion generator to provide a source of electricity. This keeps it out of the air, reducing greenhouse gasses. Treated steam produced from the sites operations is piped to a local business and used in their sanitation process. 2 wind energy turbines are installed near the top of the landfill.
- Attention to environmental safety: Extra care is taken to make sure trash that blows from the landfill doesn’t burden the local people or wildlife. Large nets are placed along the perimeter to catch trash, and a small staff periodically treks 1 mile in each direction around the site to pick up any litter that may have escaped. The site is inspected randomly each month by the EPA. Ground water from the site is tested as well, to make sure no heavy metals or other toxins are leaking through the protective barrier underneath the landfill.
- Financial Sustainability: I was surprised by the fact that though the LCSWMA is a government run operation, it utilizes NO tax revenue. They maintain the site and the pay of their employees by the sale of electricity from their WTE solutions to local utilities as well as the fees for dumping at the site. This is particularly important to my research for India as lack of funds is sited as one of the largest barriers to many of the SWM solutions that have been tried or proposed in the past. If it’s possible to run a site like this without taxing an already poor population, while at the same time providing energy to businesses and homes, this may still be an option for India in some capacity.
- Efficiency: Remember that lack of odor I noticed from the landfill? Allison explained that most of the site is used to dump construction materials and other non-organic/non-food based waste. Between recycling and their WTE plant, they manage to divert 98% of the SW away from the landfill entirely. This has extended the life of the landfill and lead to more sanitary conditions at the site as a whole. Without organic waste, wildlife largely stays away from the site (aside from a few birds I saw) and the odor is reduced. Also between the 4 sites, there are only about 100 employees, another stat that surprised me.
- Community Engagement: LCSWMA goes to a great deal of effort to educate the local population about their operations, through providing free tours, educational materials and visiting schools and universities. This community engagement is particularly interesting to me because I see it as an area I could help improve when I continue my research in India in September.I don’t have pictures of either site to show you (I was permitted to take pictures) because honestly, there isn’t much to show that would be very descriptive of my experience there. What was far more useful to me was having someone to answer my questions.
In addition to my tour, Allison provided me with a lot of useful resource information to help me further my personal quest.
Lessons for India:
I think one big caveat to note is that between cities in India and Lancaster county there is a HUGE population difference. Hyderabad is home 3.6 million people – 3x the population of Lancaster and Dauphin County combined. I am not educated enough on the economics of scale to know whether an integrated system like this would function well under that kind of population density. Still, I find the Waste-to-Energy solutions at the landfill are worth exploring because India also has an energy crisis.
Another caveat is a cultural one: India has an informal waste management stream that doesn’t exist in the US. The nearly 4,000 rag pickers in Mumbai that make their living off the landfills would need to find another source of income, if the landfills were either suddenly more efficient, or properly covered at the end of each day (A US requirement by law. Uncertain of the laws in India regarding this). Many have said, give the waste-pickers jobs at theses new plants, but when 4 large facilities only require 100 employees, that is not a viable employment alternative for waste pickers. Any benefit from sites like these in India will be environmental and public health related. Job solutions remain elusive.
So the biggest take away for India would be the need for more environmental attention utilizing WTE technology such as the methane combustion method at Frey Farm Landfill and perhaps the wind energy generators depending on the site. Also, there is an incredible amount of monitoring and accountability at this site. I suspect the history of corruption (fueled by scarcity, in fairness) in this area in India will be a challenge to overcome, but it seems mitigated here in Lancaster by the fact that those in charge of the various roles sincerely care about the role they play and their responsibility to people and the environment. We need to find those people in India, and give them these important roles.
I feel fortunate to live in a county that has such an efficient WM system and what’s more I am happy they they are transparent enough to educate the public. Without access to formal education on the topic it’s a tremendous resource for me.
In my next post I’ll talk about LCSWMA’s Waste-to-Energy Plant.
