Khyber Pakhtunkhwa is considered to be one of the greenest province of Pakistan. But the province is in a great threat of deforestation as majority of the population are cutting trees rapidly in order to meet their need of cooking fuel. Majority of the rural population are using firewood as their cooking fuel as they have no access to national gas transmission line and cannot afford the LPG cylinders. Installation of domestic biogas plant is one of the alternative green solutions to this problem. This research is conducted to evaluate the overall potential of biogas from cattle manure in KPK and to carry out the multi prospect assessment of current biogas plants in KPK. Potential of biogas from cattle manure was calculated from statistical data of KPK and literature review. Questionnaires were designed to conduct survey of 15 installed biogas plants in different districts of KPK. The total potential of biogas from cattle manure in KPK was found to be 532.9 million cubic meter per year. The equivalent potential of electricity generation from biogas is 1,344200 GWh per year. FATA regions have the highest potential of biogas which is 22 percent of the total whereas district D.I. Khan has a potential of 8 percent of the total. From the results of multi prospect assessment of current biogas plants it was found that 26.67 percent of the total plants were dismantled. 60 percent of the plants were fixed dome type while 40 percent were floating type. 40 percent of the plants were funded by the government, 33.33 percent by the NGOs and 26.67 percent were constructed by user on their own finance. 100% of the user agreed that biogas helps in firewood reduction. 92.86 percent of the users complaint about the maintenance of plant as a major challenge. 64.29 percent of the users wanted storage of biogas facility in the plant. On average, Rs. 2130 per month per household were saved in energy expenditure of cooking fuel with the help of biogas. 40 percent of plants users were satisfied, 33.33 percent were highly satisfied and only 26.67 percent responded as not satisfied.
