1. Energy crisis
With the continuous development and utilization of energy (Fig. 1), the earth's energy storage is crisis. Nothing has been found to be a perfect substitute to the energy consumption of coal, oil and other non-renewable energy resources.
A large number of energy consumption has seriously threatened the sustainable development of today's society [1]. When we keep looking for clean energy, a large amount of energy is being wasted because of our improper operations. So we have to reuse the often neglected wastes of our lives and turn them into the energy we consume.

2. Straw is an ideal renewable energy resource
Straw is an agricultural byproduct of cereal plants. It makes up about half of the yield of cereal crops such as corn, barley, rice and wheat. Take corn as an example, according to FAO statistics, global corn production in 2016 was approximately 1060 million tons (Fig. 2) [2]. Every kilogram of harvested grain produces 1.2 kg of corn stalks, giving an estimate global corn straw production is 1272 million tons in 2016.
