Scientists Urge Caution On Underwater Mining

March 30, 2023 The Silo Leave a comment

For years the ‘bad ones’ have poisoned rivers, devastated forests and displaced communities, and now massive companies are rushing to dig up the seabed for precious metals.

MIT: “The ocean’s deep-sea bed is scattered with ancient, potato-sized rocks called “polymetallic nodules” that contain nickel and cobalt — minerals that are in high demand for the manufacturing of batteries, such as for powering electric vehicles and storing renewable energy, and in response to factors such as increasing urbanization. The deep ocean contains vast quantities of mineral-laden nodules, but the impact of mining the ocean floor is both unknown and highly contested.”

And yet, only twenty-four people have the regulatory powers to stop this type of plunder in our planet’s most fragile places: The International Seabed Authority. You’ve likely never heard of them because this group attracts as little attention as an underwater mine miles offshore.

A few countries have agreed to full or partial bans, and leading scientists have appealed for a freeze on deep sea mining contracts.

Mining companies claim they can mine the seabed safely, but authorities in Namibia, Australia and New Zealand have blocked seabed mining projects. Scientists point out that many deep water species are being discovered quite regularly, and that the ocean floor can take decades to recover from disturbances such as the creation of sediment plumes from deep sea floor bed mining.

Agrarians From Ancient World Knew About Biochar

January 26, 2023 The Silo 1 Comment

Agrarians from various ancient cultures around the world discovered the soil fertility benefits of charred biomass over two thousand years ago.

Now known as ‘biochar’, this ancient soil management practice has been enjoying a renaissance of late for a number of reasons largely related to the need for more resilient and productive soils and biochar’s ability to sequester carbon in a safe and beneficial manner.

Biochar is made by baking organic material in an oxygen-limited environment, called pyrolysis. Benefits vary depending on the soil, crops and climate where biochar is used with poor soils benefiting the most. Providing long-lasting organic material, improving water and nutrient holding capacity, and improving overall soil tilth are all potential benefits.

Due to its porous nature and cation exchange capacity, biochar can also be used as a filtration medium to prevent nutrient run-off from farms into local water bodies. In Europe livestock farmers are adding small amounts of biochar to feed rations to improve feed conversion ratios and overall animal health. Biochar as carbon fodder has also shown promise as a way to reduce enteric methane emissions.

Biochar is increasingly available to purchase but farmers can also convert their on-farm waste biomass in to biochar.

Farm scale equipment for making biochar is evolving and shows promise not just as a waste conversion technology which produces a valuable soil amendment, but also as a means for farmers to generate renewable energy in the form of heat, and in some cases electricity. For the Silo, Kathleen Draper.

Seen here: “…we focused on organic plant nutrients and started multiple tests with a wide variety of nutrient rich biomass wastes including: liquid animal manure, urine, feathers, yeasts, wool, vinasse etc. Over the past four years we have developed a panoply of organic carbon fertilizer that can be produced commercially or manufactured by farmers themself all over the world. One of our favourites is the sheep wool, vinasse, pyrolyse ash, biochar pellets with 7% Norg / 6.5% P2O5 / 6% K2O “

How Your Startup Company Will Benefit From Energy Consultant

July 3, 2018 The Silo Leave a comment

If you’re just starting your own company, then it’s understandable that you’ll be very busy at first. After all, you have so much to do to nurture and grow your business. But sooner or later (preferably sooner), your startup needs to take advantage of the services of a top-notch energy consultant.

Here are some compelling reasons why you should use an energy consultant right away.

1. Size doesn’t matter. Maybe you think your company has to grow bigger first before you can enjoy the benefits of energy consulting. But that’s not entirely true. Even a small company can enjoy huge advantages when an energy consultant is on board.

2. Unbiased advice. Since an energy consultant isn’t really part of your company, you can get independent advice. You won’t have to worry about getting recommendations and findings from your employees or departments which may or may not be biased.

3. Energy usage patterns. Every company has its own patterns of energy usage. Some days and time frames will see a very heavy use of energy, while during other times there may not be a lot of energy use at all. Your energy consultant can then identify these times as part of their examination, and that can eventually help your company become more energy-efficient.

For example, it may be possible to arrange the heavy use of electricity during the time of day when the cost of electricity is at its lowest.

4. Alternative energy sources. Your energy consultant will have the necessary knowledge and experience regarding other ways of powering your business. Your company can get a comprehensive analysis regarding your possible use of these energy sources.

The report may examine several alternative sources of energy regarding their suitability for your business, and these may be solar energy or wind turbine power. The energy consultant may find out exactly how much it will cost your business to buy and install these systems. They may also determine how long it will take to complete the installation, and how easy it is to operate these systems. At the same time, the consultant can also find out exactly how much money you can cut from your current energy bills.

5. Using green energy. Many businesses today focus on being environmentally friendly. It’s not just right for the world, but it’s also right for your business as you can include your use of green energy as part of your marketing plan. When your company can help reduce carbon emissions, you can make your place and your neighborhood healthier, while it also boosts the reputation of your company.

6. Regular advice. Your energy consultant may be asked to come in on a regular basis. Because of this, your company may keep current on the latest developments regarding the use of renewable energy. This means you’ll learn about new technology and changes in alternative energy laws. Also, your energy consultant can fine-tune your use of alternative energy and also make sure that your renewable energy system is running at peak efficiency. For the Silo, Dimitry Karloff.

Green Party Emphatic No To Proposed ‘Tar Sands Oil’ Pipelines In Ontario

July 24, 2013 The Silo 3 Comments

Ottawa – Green Party leader Mike Schreiner is pledging to fight two oil pipeline projects through Ontario. Joining Ottawa South candidate Taylor Howarth on a campaign tour, Schreiner and Howarth raised concerns about the health, environmental and economic effects of TransCanada Corp.’s proposed east coast pipeline, which travels through Ottawa, and Enbridge’s proposed Line 9 pipeline. Both projects
will pump tar sands oil east.

“Greens will fight for the health and safety of our communities,” says Schreiner. “If BC can say no to dirty oil pipelines, Ontario should too.” TransCanada’s proposed Energy East pipeline could transport as much as 850,000 barrels of tar sands oil per day. The project would require retrofitting a 55 year old natural gas pipeline to handle the heavy, more abrasive and corrosive tar sands oil.

“I don’t want to see a tragedy in my community, and I will fight to prevent it,” says Howarth. “This pipeline was not built to handle tar sands oil, and as MPP, I will push the Ontario government to oppose the project. Every vote for the Green Party sends this message to Queen’s Park.”

According to the Montreal Gazette- Municipalities and Counties strung along the Line 9b pathway received cash donations from Enbridge. CP

Studies in the U.S. reveal that pipelines carrying tar sands oil spilled almost three times as much crude oil per mile of pipeline between 2007 and 2010 compared to the U.S. national average. And heavy tar sands oil is more difficult and expensive to clean up than light crude or natural gas. “Both of these pipeline projects are a bad deal for Ontario,” says Schreiner.

“These pipelines are all risk and no reward.” Instead of projects that will increase pollution and greenhouse gas emissions, the Green
Party is calling for policies to support clean tech innovation. “Ontario must invest in where the puck is going, not where it is, to create jobs and clean prosperity,” says Schreiner. “Ontario should commit to building electric cars that don’t pollute and support made in Ontario renewable energy, not pipelines that threaten our communities.” For the Silo, Becky Smit.
