Soil Carbon Sequestration

This year has seen numerous unprecedented weather events, many of which scientists say are driven or exacerbated by climate change1. The vast majority of the scientific community are well aware that climate change is occurring due to excess greenhouse gas emissions, resulting in increased carbon in the atmosphere. However, did you know that soils actually contain more than 2 times the amount of carbon than is in the atmosphere?

Biosolids and Soil Health

At the recent Summit on Canadian Soil Health in Guelph, Ontario, Don Lobb, a farmer and conservation leader in Canada emphasized the importance of proper management of soils:

“No civilization has ever survived the consequences of exploitative agriculture. As soil was degraded, the survivors moved on to new frontiers. Today, there are no new frontiers. We must take advantage of the one opportunity left- intensive, scientifically sound, responsible soil management that accommodates a healthy soil biota community”.

When you are done eating an apple, you have a few different choices in terms of how to dispose of the core. If you simply throw it in the trash, it will end up in the local landfill and become just one more addition to the problem of global waste. However, if you compost that apple core, or place it into a green bin or equivalent organic “waste” collection unit,  the inherent nutrients can be returned to the soil as part of a more natural and sustainable, life cycle. Many of us have come to understand that this approach is far more sensible – and preferable, to landfilling. Moreover, new technologies and management methods are further expanding our field of options. Included in this are approaches like co-digestion of organics and biosolids at wastewater…

When seasick on the ocean, water will seem entirely overabundant. But not all water is equal and while seawater is great for fish, without expensive desalination, it doesn’t provide any of the drinking, cleaning or irrigation uses for which people need fresh water. That type of water – the kind that can be easily and safely consumed – is in relatively short supply.

Only a small fraction of the earth’s water resources is potable and the twin pressures of climate change and global population growth are squeezing our clean water supplies tighter than ever before. The developing world has been hardest hit, but North America is increasingly facing the same problem of maintaining both the quantity and quality of our precious clean water supplies. (more…)

In celebration of Earth Day 2017, let us reflect on the vital importance of wastewater as a widely available and valuable resource. Recently made available, the 2017 United Nation’s World Water Development Report recognizes wastewater as an untapped resource and an important contributor to the health of the planet.

The UN Water report is justifiably optimistic about the advancement of new technologies for recovering wastewater energy. (more…)

World Water Day is a great time to reflect on how fortunate those of us that have clean, safe, drinking water really are. Much of the world is not so lucky.  Therefore, it is critically important to think about how we care for our precious, water resources.

While having quality, drinking water is more appreciated than ever; wastewater is still often viewed as “waste”. We are honored and excited to be part of a team that is working hard to change this perception with innovative, safe and efficient solutions for better use of wastewater resources.

Here are 10 good reasons why properly managed wastewater resources should not be wasted;

Thinking About Biosolids; Joining the Movement from Class B to Class A

Historically, most of us did not think about biosolids.

For many years, this potentially valuable material was viewed as something we had to “get rid of”. It was dumped into landfills, over-applied to farmlands (i.e., not at proper, agronomic rates), buried in remote locations and/or otherwise “disposed” of. In those days, there were few choices in terms of the safe and proper treatment of this amazing resource. There were also legitimate concerns with things like pathogens and metals in biosolids.

Today, however, thanks to decades of careful research and advancements in the science of wastewater infrastructure and treatment, we know that it is possible to retain the good in these raw resources and produce of exceptional quality derived from biosolids. These advancements are allowing us…

The city has formally approved plans to implement Lystek Thermal Hydrolysis solutions for biosolids management

This project will play an important role in converting the facility into a Water Resource Recovery Center (WRRC).

“We are pleased to be moving forward with the implementation of the Lystek technology” says Justin Lawrence, Director, Environmental Services and City Engineer for the City of St. Thomas.

The city’s current plant is a conventional wastewater treatment facility. It provides wastewater services to St. Thomas and the surrounding area. Wastewater flows through the city’s sanitary sewer systems and 12 pumping stations and is collected at the WPCP for treatment.

With a current, rated average daily capacity of approximately 27,300 cubic meters or 7,212,000 U.S. gallons per day, wastewater is treated and subsequently safely released to the local waterway…
