Dear Md Mostafizur Rahman ,

Since 1980 we replace fossil fuels worldwide by biomethane which we produce from a broad range of organic wastewaters and wastes at up to 99% efficiency (certified). Our AD+™ plants get paid back within 3 to 5 years by the savings in fossil fuels, in chemicals + electrical energy to purify the wastewaters and in wastewater sludge and waste to dewater and dispose. By adding solar PV panels we minimize the electrical power consumption of our bioprocess. More on https://modelengineering.eu/circulate

That the need for energy is in line with population growth and economic growth, the trend will continue to increase, while supply is increasingly running low and this happens in all countries and makes energy a global issue. Currently, the world's energy supply is still dominated by fossil-based energy which is claimed to be a contributor to greenhouse gases. The world realizes that over time the supply of fossil energy is running low and the trend has begun to shift to new, renewable energy. This energy is now a necessity, no longer an option, no longer an alternative. It's my opinition Bruno Peeters . Thank you.
