Abstract.
Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures without the participation of oxygen, or with very limited air [1].
A typical pyrolysis process chart for manure processing is shown in figure 1, as the fresh manure normally has high moisture, a pre-treatment process to dry the raw material is needed.
When the Qgas=Qin-NRS the input material moisture is 36.63%, and when the Qgas=Qin-VRS, the input material moisture is 48.18%, which is 11.55% higher than the former.

The excited CB and NB hole would reintegrate to eliminate the input energy and heat, the electron could be caught on the material surface state, the NB electron transits to CB, the NB hole takes the surrounding hydroxide electron and transforms hydroxyl into free radical, as a strong oxidizer to degrade the organics (or containing chlorine), and finally kill the bacteria and virus.

Sunlight greenhouse temperature impact factor
Sunlight of Greenhouse internal temperature of the greenhouse environment mainly by: the decision to outdoor weather conditions, the construction of the structure of solar greenhouse covering material materials, indoor control equipment operation, and other types of indoor cultivation of crops combined effects of many complex factors
Outdoor temperature, wind speed, light intensity and other external weather conditions have a direct impact on the solar greenhouse internal temperature, no doubt as a factor affecting the indoor temperature.
Greenhouse transmittance before roofing materials have a direct impact on the level of indoor heat, light transmission rate will change over time with the use of.

Rees [5] referred to the EF as the ‘appropriated carrying capacity’, and biocapacity (BC) is defined as the carrying capacity of local ecosystems to produce useful biological materials and to absorb waste materials generated by humans.
For example, Senbel [29] examined several scenarios for human consumption, ecological productivity and material efficiency to explore which variables would have an influence on the ecological budget of North America over the coming century.
