Nicaragua biogas and coffe program help to mitigate climate change effects

the project has been implemented in a range of differently sized farms, and achieved results ranging from preventing local deforestation to better indoor environments for families who replaced firewood with domestic gas stoves for cooking.

Coffee farmers in Nicaragua are generating biogas and promoting eco-friendly environmental practices. Wastewater treatment systems and solid waste management plants have been installed in eight coffee farms in the country. Promoted by UTZ Certified, the Sustainable Energy and Coffee Waste Management project is helping to produce biogas, mitigate climate change and protect water resources.

Tailor-made coffee wastewater treatment systems and solid-waste treatment mechanisms were installed in eight coffee farms in Nicaragua, ten in Honduras and one in Guatemala. The positive environmental and economic impact of the project on over 5,000 people in the region has inspired UTZ Certified to replicate the initiative in other countries.

Additionally, coffee wastewater comes along with tonnes of organic waste and high toxicity, which UTZ said affects the soil and generates considerable amounts of greenhouse-gas emissions, particularly methane, heavily contributing to climate change. 

The organisation said that the project has been implemented in a range…

RENEWABLE ENERGY AND ALTERNATIVE FUELS

The cost of power generation is increasing and depletion of non-renewable sources is of great concern. We must continue efforts to improve technologies of renewable power to reduce the cost of infrastructure and delivery.

Cielotech Online

There is absolutely no doubt the entire world is dependent upon the generation and transmission of electricity.  Those countries without electrical power are considered third world countries with no immediate hope of improving lives and living conditions and yet there just may be alternatives to generally held methods for generating electricity.

If we look at the definition for renewable energy, we see the following:

Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

POWER GENERATION:

We are all familiar with current methodologies for power generation.  These are 1.) Hydroelectric, 2.) Nuclear, 3.) Coal-Powered, 4.) Oil-Fired, and 5.) Generation using Natural gas.  The graphic below…

From Hand to Land – Thoughts from the Landfill

Each trash heap represents the contents of one municipal trash truck. A compaction tractor then drives over the mounds, again and again, gradually flattening them. Finally, the flattened mounds are covered with a layer of dirt. Neither cement, nor plastic liners are used to protect the surrounding ground and water table, at this particular landfill.

I decided to take a short drive to the local landfill, this morning; with the intention of exploring my town’s waste management strategy.  I’d like to develop my understanding of what landfilled waste disposal actually looks like.  I want to create and maintain a visual reference point, of the ultimate destination for trash; so that I can truly comprehend the scope of what I/We are up against, in the War Against Waste. (#waragainstwaste)

When I think about trash, and what its’ life cycle looks like, (yes, believe it or not, trash has a life cycle), I imagine something like one of those connect the dots pictures, popular with children.

It is not that I desire to oversimplify the issue, because the topic of waste production and management is one of great complexity, and seemingly endless tendrils of cause and effect.

However, what we really need to do, if we want…

AIESEC India – Lucknow’s Waste Management Crisis

Equally important to a top down approach required by the government to put the correct municipal infrastructure in place, is a bottom up approach from the people of India. Having spoken to different generations of people from Lucknow, a range of attitudes was made apparent.

Global Interactions

During my time at the University of Sheffield I became involved with AIESEC, a global student run organisation facilitating youth leadership through international internships. My interest in environmental issues arising from human impact took me half way round the world to Lucknow – a city in the north west of India where fellow AIESEC members were involved in a project called Conserve. The project was tackling a huge range of environmental issues affecting the city, however our given role (along with members from many other countries) was to provide a fresh outlook – to focus on the most pressing environmental issue and develop a strategy to best tackle it.

One of the most tangible and obvious problems suggesting itself to us in Lucknow was the issue of waste management – a problem not just unique to Lucknow, but affecting India as a whole. It was clear from walking down any…

Do you purchase bottled water? Buy a water bottle instead

What is a good alternative to bottled water? Buying reusable water bottles made of either glass, metal or even plastic. The plastic for reusable water bottles is different than the one time use bottled water because it is durable (lasts longer), dishwasher safe, and in many cases it is BPA free. Reusable water bottles are also a one-time payment, whereas bottled water has a price for every bottle purchased.

Do you drink bottled water on a daily/weekly basis? If so, is it because you have to, or is it your personal choice? If it is a personal choice, perhaps it is time for you to choose a different alternative. Bottled water is convenient and for the most part it is easy to find. However bottled water has many negative effects on the environment. Did you know that although most bottled water claims to be from fresh spring waters, about 25-40% of it comes from municipal sources (tap water)? Bottled water also produces around 1.5 million tons plastic each year which is close to 50 million gallons of oil needed to produce the plastic. Although plastic bottles can be recycled, over 80% are thrown away. This is bad for the environment because plastic takes a long time to decompose in the landfill.

What are the differences between Biofuel, Bioethanol, Biodiesel, and Biogas?

Large-scale commercial biogas projects are proving viable globally. Nordic countries such as Norway and Finland are on board with 1/3 of Oslo city buses powered by biogas from sewage.

The Sustainability Co-Op

By Lauren DeMates.

Put simply, biofuel is energy made from living matter, usually plants. Bioethanol, biodiesel, and biogas are types of biofuels. Biofuels are considered renewable energies, emit less than fossil fuels, and have received increasing attention in the transition to a low-carbon economy.

Bioethanol (aka ethanol) is the most well know biofuel and is an alcohol produced from corn, sorghum, potatoes, wheat, sugar cane, even cornstalks and vegetable waste. It is commonly blended with gasoline. However, plants grown specifically for any type of biofuel are not ideal due to the energy required, environmental impacts, and emissions associated with harvest and transport; not to mention the subsequent increase in global food prices. However, bioethanol production in the U.S. (mostly corn) has been increasing since the 1990s. Almost all gasoline currently sold in the U.S. is 10% ethanol due to the Renewable Fuel Standard (RFS), which dictates the amount of renewable fuel that refiners…

Food Waste Wasted in Landfills

By the time your food waste gets to the landfill, it’s already begun to decompose as the microbes all around us begin to eat away at it. This process releases carbon dioxide and methane, both greenhouse gases. Inside the landfill, the process continues and the gas eventually escapes from the landfill.

FUELward Thinking

In the United States, most of the food waste we produce is sent to landfills. This is more than just the uneaten food you scrape off your plate at home, or the spoiling produce you forgot about in the fridge. Huge amounts of food are thrown away at restaurants, grocery stores, and institutions every day. Why do we still do this? Why is it O.K. to entomb this stuff in the ground together with all the other things we throw away that don’t readily degrade, many of which we know will not degrade for thousands of years? Food waste is readily degraded, but when it happens in a landfill mixed with all this other stuff, it causes some problems.
