How Can You Produce Your Own Biogas?

The idea of biogas is anything but new. People have been experimenting with making biogas for many generations. Biogas is made by converting organic waste into energy. It’s a huge win for the environment because it utilizes what is otherwise considered waste, but it’s a big win for pocketbooks too.

Organic waste includes the byproducts of human food production (think potato peels, carrot peels, the tops of turnips, etc) but it also includes manure. Any manure is fair game, think about cows, pigs, chickens, rabbits, goats — virtually any farm animal produces mounds of this each day.

This manure produces very high levels of methane gas which is horrible for the environment. By using this manure to create biogas, we remove the danger of creating heat-trapping gases in our atmosphere that raises the temperature of the entire planet. Using it for biogas production can also help to reduce global warming.

How Do We Produce Biogas?

Biogas is produced from the breakdown of organic waste in an environment that is void of oxygen. We call this environment anaerobic and the process is process is called anaerobic digestion. Two products are created from this process. One is digestate. Digestate can be used for fertilizer and even as livestock bedding.  The other product is biogas. Biogas can be used for heating, electricity production and as a clean vehicle fuel.

It’s essentially like composting all of the materials, but in an environment without oxygen and in the temperature range of around 35 to 40 degrees Celsius and pH of around 7. This is optimal to produce biogas. Biogas can be converted into an upgraded form of gas by removal of carbon dioxide that can be used like natural gas. It can be used as-is as an engine fuel. It can be used as fuel in a vehicle, sometimes without modification.

How Can You Produce Your Own Biogas?

Just imagine being on your own off-grid property, running a hundred head of cattle, growing your own food and canning it. You’ve got meat covered, your food is stocked and you are prepared for just about anything. But what about fuel? Imagine what a game-changer it could be if you were able to produce your own fuel from the waste from your cattle and your garden scraps or food residuals! You can!

The Biogas Digester makes it possible, and fairly easy, for you to start producing your own biogas. Buy a ready-made biodigester for around $700-$1000 dollars and start producing your own biogas to meet your fuel requirements. They are containers designed to do the work for you and help you collect the fruits of your composted and digested waste.

Build your own! China has approximately 30 million Biodigesters in use in its rural areas. Rural Chinese areas are far removed from cities that have gas stations. It simply isn’t accessible as it is in the US. Many rural people have learned to make their own biodigesters to fill their fuel needs.

You need a tank that is sealed with an access hole on one side for adding organic waste. You have another access to an outlet. That is where you collect the liquid run-off that can be used for fuel.

The bottom of the main unit is the digestion chamber. From that is an outlet where the digestate can be collected and used as fertilizer. The main chamber typically has a domed top to allow for the room that will be necessary for the expansion of the gases formed inside. By being sealed, the unit creates that all-important anaerobic environment.

Zero Waste Trends to Watch

Most people have heard about concepts such as single-stream recycling, but there’s another approach known as zero waste. People who support the concept of zero waste agree that, in a broader sense, it means reducing dependence on landfills and increasing reliance on material recovery facilities. But, after that, the definition varies primarily based on industries, manufacturers and even entire countries.

Even so, there are inspiring trends that show how people and companies are working hard to reduce the amount of waste produced, thereby getting ever closer to that desirable zero benchmark. Below are some of the major trends taking place across the world in the field of zero waste:

More Reusable Packaging

We live in a world where it’s possible to order almost anything online and have it quickly arrive on a doorstep — sometimes the same day a person placed the order. And, society loves the convenience, but the dependence on delivered products causes an increase in packaging materials.

It is often astounding how many packing peanuts, layers of bubble wrap and cardboard cartons come with the things we buy. And, the manufacturers and shipping companies consistently bring up how boxes get dropped or otherwise mishandled during transit, making the extraordinary amounts of protective packaging products necessary.

On a positive note, a company called Limeloop makes a shipping envelope designed from recycled billboard wrapping people can reuse thousands of times. Another company called Returnity communicates with distributors to urge them to use the establishment’s boxes and envelopes, both of which people can rely on dozens of times instead of throwing them away after single uses.

Ceramic Mugs in British Coffee Shops

In some regions of the world, customers who visit coffee shops don’t get asked whether they’ll be drinking their coffee on site or taking it with them to go. However, many leading coffee shops in the United Kingdom find out that detail from customers who order drinks, then serve the beverages in non-disposable mugs to people who’ll enjoy their purchases on the spot.

Also, all 950 Starbucks locations in Great Britain recently began charging customers five cents for getting their drinks in disposable cups. Conversely, it rewards them by taking 25 cents off the costs of their orders when they bring reusable cups into the stores.

Creative Ways to Cut Down on Farm Waste

Manure (or fertilizer) is a reality on farms around the world. And, the commercially bought versions of it contribute to excessive waste and inflated costs. Some even harm future growth when farmers apply manure too heavily and negatively affect the soil’s balance.

But, besides avoiding commercially-sold manure and not applying it excessively if used, what else can people in the agriculture sector do to make farm waste more manageable? They can look for unique outlets that may want to buy it.

One startup uses a detailed manure-refining process to extract the cellulose from cow dung. Business representatives then use the cellulose — a byproduct from the grass and corn cows eat — for a new kind of fabric.

What about using animal waste for energy? A forward-thinking farmer did that with his manure lagoons, making them produce biogas that powers homes.

These unusual solutions highlight unconventional use cases for animal droppings, such as poultry litter, that support zero-waste goals, provided farmers want to explore them.

An Uptick in Reusable Food Containers

People often pack their lunches in plastic containers before heading off to work, but when they get food delivered or pick it up from a provider to eat at home later, the associated containers usually fill up garbage cans after people chow down.

Some facilities are trying to change that. At The University of California Merced campus, a pilot program occurred where students who stopped by dining halls for meals to take away brought reusable containers with them. After people ate the food from them, they could return them to get washed and ready for future meals.

Moreover, a pizza restaurant in Wales provides an aluminum box for people to use again and again when taking their pies home. One of the problems with cardboard pizza containers is they can’t be recycled when contaminated with grease. However, people can buy the metal ones for a small, one-time fee.

Opt for reusable containers for food and beverages

Then, by using them, they get 50-cent discounts on their pizza. The restaurant also backs the boxes with a lifetime guarantee and will replace them for no charge if necessary due to breakage or damage. Also, because metal conducts heat, the material helps pizza stay hotter for longer than it would in cardboard boxes.

Innovations to Complement Commitment

Adhering to a zero waste lifestyle undoubtedly requires dedication and a willingness to look beyond old habits. However, for people who show those characteristics, numerous inventions and improvements make it easier to do away with the throw-away culture.
