• Biogas from waste digestion plants is used to make bio-methanol. 

• Fertilizers are chemical substances that are applied to crops in order to boost their yield.
• Farmers utilise these on a daily basis to boost crop productivity.
• The fertilisers include nitrogen, potassium, and phosphorus, which are all vital minerals for plants.
