Application of Biochar on methane production through organic solid waste and ammonia inhibition

open access: yesEnvironmental Challenges, 2021
The present study discusses the role of biochar in enhancing methane (biogas) production from organic solid waste (OSW) employing a co-culture of Pseudomonas aeruginosa and Methanosarcina mazei.

Study on the best time of refracturing for Hancheng coal seam

open access: yesMeikuang Anquan
The old wells in Hancheng Block face the problem of production decline after long-term exploitation, and need to be re-fractured to form new fractures to communicate with CBM rich areas, so as to achieve stable CBM production. Due to the small difference

Carbohydrate Type and Level Affect in Vitro Methane Production from Cecal Contents of White Roman Geese [PDF]

open access: yesBrazilian Journal of Poultry Science
The type of carbohydrate diet is an important factor in methane (CH4) emission from livestock. In this study, a structural carbohydrate (rice hull) was tested as a feed ingredient and compared with the use of a non-structural carbohydrate supplemented to
