Do you want to reduce your impact to the environment? Or are opting for less-costly energy production?
Well, here on the Leafy Agenda,we had earlier discussed the benefits of Green Energy such as Biogas in the article Biogas in Kenya.
Did you know? Combustion of Biogas converts methane into CO2 gas. This greatly reduces the Green House Gases effect through the numerous Carbon Dioxide emissions, over 20 times. This is an effective way to reduce your carbon footprint.
Methane gas, which makes up 50-75%, and other constituent gases of Anaerobically produced Biogas can be hazardous if not handled correctly.
Here are some tips to ensure safety for Biogas users:
- No open flames should be allowed near the digester. Biogas,which also comprises of potent Hydrogen sulfide and ammonia, is highly flammable therefore lighting fires near the digester should be discouraged.
- Keep electrical appliances such as electric generators and big engines away from the digester. This is because any spark originating from these appliances, may ignite the gas and cause an explosion.
- Make sure the manure is stored in open-air environments, and not in enclosed or poorly ventilated spaces. Due to the accumulation of Methane gas, one may experience asphyxiation, or suffocation, as a result of lack of sufficient oxygen gas, leading to breathlessness or worse, death.
- Invest in a good biogas system construction, from a reputable company. A good biogas system should be :
- Tightly sealed with good aeration.
- Built with an expansion chamber to accommodate the released gases. Some biogas digesters are built as dome-shape designs for maximum capacity.
- Best constructed near the source of waste, i.e near cow shed or septic tank.
- Mixed with water to ease the flow of the manure down the biogas digester to the slurry pit.
- Constructed from high quality materials
- Maintain high levels of cleanliness around the biogas digester.
Last but not least:
5.Biogas is produced from various sources such as human and animal manure, and also organic waste. This environment is ripe for rapid multiplication of disease-causing Bacteria and thus:
- Biogas plants should be constructed away from drinking water, particularly if using human waste.
- Construct the biogas digester away from food crops’ garden.
- If near a garden, it should be layered well under-earth to prevent leakage that may leak to your food crops.
- Biogas digesters should be away from where animals feed, to prevent infection to your animals
- Biogas plants should be constructed out of reach from children. Children playing near the Biogas digester may be exposed to leachate or the harmful gases.
- Maintain high levels of hygiene when handling the manure: Wash your hands thoroughly after working around the Biogas digester, to prevent infection to you and your loved ones.
- Ensure to use PPE’s: Personal Protective Equipment such as gumboots and industrial gloves when handling the manure.
- You can install gas sensors that alert you in case of a leak. This will go a long way in preventing suffocation, explosions and other dangers associated by hazardous gases.
- Keep the area around the Biogas digester as clan as possible: this will minimise insects such as houseflies and cockroaches at an all-time low. This also gets rid of odious smells that emanate from the biogas digester.
Keep on Going Green. :-)
