From Poop to Power: The Possibilities of Decentral...

The world has a poop problem. According to the World Health Organization, 2.6 billion people lack access to any sanitation. For those that do, sewage infrastructure is often underdeveloped or unreliable. Globally, this leads to more than 200 million tons of human waste goes untreated every year. In developing countries, most of this waste ends up in lakes, rivers and oceans, where it contaminates sources of drinking water. Untreated sewage and polluted water sources are serious issues for public health, estimated to kill 1.4 million children each year. New, cost-effective technologies for handling waste hope to combat these startling statistics.
Singapore Sets Its Sights on the Future: A Pilot P...

Singapore is a country that is smart about recycling. With limited land space, this island city-state has had to get innovative when it comes to resource management. When it became clear that the rate of waste disposed by its citizens had risen six-fold between 1970 and 2000, Singapore decided to lay out an ambitious goal to achieve a zero waste, zero landfill future. The 2002 Singapore Green Plan 2012 (SGP2012) created a 10-year blueprint designed to address the challenges of sustaining Singapore's environmental vision despite increasing population and development pressures. It set a strict 60% target for ...
How Smart Green Cities Turn Waste into a Resource

Big problems call for smart solutions. By 2050, the world population is expected to grow from 7.2 billion to 9.6 billion and it is estimated that 66% of all people will live in cities (up from 54% today). Looking at these numbers, it's easy to understand how climate change can be considered the most important challenge of our time. Faced with a future of rapid urbanization, increased resource scarcity, and rising temperatures from greenhouse gas emissions, we are being forced to consider how urban environments will be designed to support the needs of our offspring while sustaining the ...
New Business Models in Waste Management
December 23, 2015
In our previous posts, we talked about how waste—which has long represented a cost center—is nowadays being transformed into a profit center. From this emerging circular economy, a multitude of new business models are arising. Each of them demonstrate how there are many profitable ways to turn trash into cash and simultaneously be kind to our planet.
In this post we'll dive into a few of these business models, using Regreen machines as an example of how new "smart" waste management technologies fit into the profit picture.
Typically, when businesses talk about corporate sustainability, they are talking about meeting regulatory, marketing, or public awareness goals while trying to minimize impacts on cost. They then use indir...
Turning Trash to Treasure (#3): The New Circular E...
November 24, 2015
As Einstein once stated, "Energy cannot be created or destroyed, it can only be changed from one form to another". The Law of the Conservation of Energy is one of the most basic laws of science and it means a whole lot when we apply it to the things we throw away. See, energy is stored in everything from the foods we eat to the plastic toys our children play with. This means that when our trash gets taken to landfills, it becomes not only an environmental burden, but a wasted source of energy.
Trash is simply treasure that is yet to be transformed into something valuable. In our last posts, we explored how organic waste is being converted into products like compost and animal feed. This time, we'll explore how waste can be used to power ...

November 10, 2015
As the saying goes: "One man's trash is another man's treasure". In our last post, we started to explore how a new economy is forming around the things we throw away. We looked at how emerging "smart" waste technologies can quickly transform organic waste into compost, creating savings for waste producers while forming a loop that takes food from farm to fork and back to farm again.
Compost isn't the only recycled waste product that completes the food loop. In this post, we'll explore how animal feed created from food scraps and plant-based materials (biomass) offers another innovative and profitable solution to the problem of organic waste filling up our landfills.

October 29, 2015
Let's face it; waste isn't what it used to be: a problem with no solution. Aided by the rise of new "smart" waste management technologies, trash is beginning to be understood as a renewable resource for material and energy recovery. As waste is transformed into commodities that boast both environmental and economic benefits, a circular economy is forming around the things we throw away.
Here's what it looks like:
Waste to fertilizer, compost, and mulch
Waste to animal feed
Waste to energy and fuel
This waste revolution is being driven in large part by environmental and political pressures that are pushing for diversion of waste from landfills. One of the biggest culprits of gr...
Did you know that United States landfills are clos...
April 08, 2013
Our largest cities are scrambling for alternatives.
While we wish the landfill closure rate were an indicator that we are producing less trash as a country, it is actually (and unfortunately) an indicator that we are running out of space for where to put it. It's a recipe for a train wreck, and the situation must urgently be addressed. Here's a look at three major US landfills that are closing this year and how that will affect the surrounding communities and environment.
Puente Hills Landfill, California
The Puente Hills landfill has serviced Los Angeles County for over 70 years, and now it has run out of space. It is one of the largest landfill sites in the country, and its closing is considered by many to be the beginn...
There may indeed be a way for hotels to become ene...
October 10, 2012
The problems hotels face with their energy bills are widely recognized throughout the industry and in the government as well.
A study conducted in 2003 by Energy and Environmental Analysis, Inc. has found the total energy bill for hotels in the US to be $5.2 billion 5% of total industry revenues. And the amounts have only risen since then. After all, not only does the industry have to power over 4.4 million guest rooms with electricity, heating, and air conditioning, many hotels also have restaurants, nightclubs, spas, health clubs, casinos, and multiple other attractions and entertainment venues. And they have to operate around the clock year-round.
The hotel industry is already exploring a possible solution for reducing their c...

Despite its history, fuel cell technology wasn't adapted for commercial and industrial use until the 1990's, and only began to be sold commercially around five years ago. Because of that, not many people know how fuel cells work.
A fuel cell is a device that uses hydrogen gas and combines it with oxygen from the air to create electricity and heat. It consists of two electrodes (which are plates capable of conducting electricity) called an anode and a cathode. These electrode plates sandwich a layer electrolytes.
When hydrogen gas comes from one side of the cell and hits the electrode plate, a catalyst that is integrated with the plate forces the hydrogen molecules to separate into protons and electrons. The protons pass through t...

Currently, over 65% of the world's electricity is produced through fossil fuels powering turbines.
But experts in turbine technology have already confirmed the enormous potential of replacing fossil fuels with biogas - gas made from the breakdown and recycling of organic materials such as food waste. Let's explore some of the environmental and economic benefits that can come from using biogas as a source of electricity.
Most of our electricity today comes from fossil fuels. It is produced either through steam turbines, in which the fuel is a heating agent that boils water to create steam that turns turbines. Or the fossil fuels could be used in gas turbines, which use burning gas to turn turbines directly (without the use of wate...
