DIY Biogas Make and Use Your Own Renewable Natural Gas

Make your own homemade natural gas from food scraps, garden trimmings, and animal waste!

Understand how to craft a recipe to make your own renewable energy substitute for natural gas and propane.

DIY Biogas contains complete plans and parts lists with active links (Kindle edition only) to build two different biogas generators that help you learn, understand, and grow your biogas operation. With this hands-on, minds-on guide, you’ll gain the knowledge and experience you need to convert waste into energy. Whether you’re looking for a unique science project or want to cook meals with your own backyard biogas, this book is the most practical place to start.

With fuel prices and scarcity on the rise, it’s time to re-learn how to meet our own energy needs. Start today and harvest your own local, renewable energy resource tomorrow!

3 PRIME STAGES TO INITIATE BIOGAS

3 STAGES TO INITIATE BIOGAS:

1. Maturation of fresh cow dung starter

2. Acclimatization of matured starter to new waste

3. Optimization of feeding to obtain best ratio of waste to water, temperature and digester size for routine feeding

AT FIRST MY GAS IS BURNING BUT THEN STOP PRODUCING. WHY?

So, when the the first batch of biogas is produced, it showed that your dung starter is already matured and ready to produce next batch of biogas. But it is only the beginning. The number of microbes have already multiply several folds compare to fresh dung. Matured starter can produced biogas faster then fresh dung. However, you cannot jump to conclusion that you can add any waste in any amount. How would you push microbes from dung to suddenly adapt to digest waste from different sources? It is impossible! You have to start slowly introducing alien waste into this matured starter. So that these microbes could first learn to recognize then adapt to the new waste. Introduce the new different waste little by little until the sensitization process is complete. Introducing large amount of alien waste to a new digester will cause your starter became shock and stagnant. Give them time to learn. They are not machine but only living things like us. Have mercy ok.

WHY MY GAS IS NOT BURNING?

When I first initiate my digester with zero knowledge about biogas my favourite question was why is there no any gas produced? So you are very lucky if there is gas production by the new digester because carbon dioxide will come out first in the beginning before then methane. You have to understand that biogas is actually mix of several type of gas like carbon dioxide, methane and other inert gas. Along the process of biogas production, in the beginning of chain reaction, acidification will first occurr thus producing carbon dioxide. It is normal to have carbon dioxide in the very beginning. It is a positive sign that your digester is working well and will produce methane a bit later according to the chain reaction. Unless your digester is continuously producing carbon dioxide after months of starting then you have to start worry there might leakage somewhere along digester system.
