Agricultural mulch films, typically made of petroleum-based polyethylene, improve crop productivity by controlling weeds and providing microclimate. Extreme fragmentation of films imposes labor and disposal costs, not to mention environmental problems during and after service life. Although mulches made of biodegradable polymers such as cellulose, (nonbiobased) poly (butylene adipate-co-terephthalate) and polybutylene succinate are employed in the field, the fate of biodegradation of additives in mulches is still questionable in addition to service life until the harvesting. Nonwovens, made of biobased polymers such as poly (lactic acid) (PLA) and PLA-polyhydroxy alkanoate (PHA) blends, have been developed using nonwovens textile technology to …

Pretreatment is a unit operation in the conversion of biomass to valuable products that utilizes various combinations of conditions, including chemicals, heat, pressure, and time, to reduce the recalcitrance of lignocellulose. Many such pretreatments have been developed over the years, as the operating conditions can be adapted so that lignocellulose is modified in ways unique to each pretreatment. By tailoring pretreatment conditions to achieve these modifications, the types of final products produced can be controlled. The purpose of this review is to provide a consolidated source of information for sodium hydroxide effects on lignocellulose. The structural characteristics of lignocellulose and …
