“…In t, eggplants achieved the best growth rates and canopy in greenhouses cladded with 0% UV films [15]. Best tomato production was recorded in experiments where the biodegradable was used as mulching material in place of plastic film or bio-based films [30]. The results te that the type of plant dictated the choice of greenhouse covering or mulching material.…”

“…Even though cladding materials influence plant growth rates and the quantity of PAR and UV-A radiation, the performance of the greenhouse materials and microclimate is also predicted by the usage of plastic-based mulching or bio-based mulches [30,35]. Heat retention in greenhouse structures is dependent on the type of materials used in the construction of the greenhouses.…”

“…Heat retention in greenhouse structures is dependent on the type of materials used in the construction of the greenhouses. According to [30], the performance of wall materials varies depending on locality-greenhouses in arid and semi-arid areas require better insulation from heat, while pure and bioplastics have different levels of susceptibility to UV degradation. Plastic films experience the least deterioration (1.5.to.…”

“…The primary materials used in greenhouse cladding are glass, plastics (sheets and films), fiberglass reinforced plastics, biodegradable paper (synthesized from degraded coal or plant straw), shade cloth [36], polycarbonates, poly (lactic acid) (PLA), and polyhydroxyalkanoates (PHA) [18,30,37]. Glass is preferred as a cladding material for greenhouses due to its high transmission of PAR and reflectance of NIR leading to diminished greenhouse energy balance.…”

The fundamental objective of the review article was to explore the ecological sustainability of greenhouse covering material based on the following themes; considerations for greenhouse materials, properties of polymers and glass, additives, fillers, stabilizers and reinforcements, performance, Ultraviolet (UV) transmittance, phase change materials (PCMs), and environmental sustainability. A comparison of various polymers (polyvinyl chloride (PVC), acrylic, D-polymer, Linear low-density polyethylene (LLDPE), polyolefins), and silica glasses illustrated that each type of greenhouse cladding material has its unique merits and limitations. The performance of silica glasses, PVC, polyolefins was influenced by weather, greenhouse design, plant under cultivation, percentage UV transmittance, incorporation of additives and stabilizers, reinforcements, and integration of photovoltaic panels into the greenhouse roof among other factors. Polymers can be customized to achieve 0%UV transmittance, slow-insecticide release, and anti-microbial properties. In contrast, glass materials are preferred based on suitable photosynthetically active radiation (PAR) transmittance and near-infrared (NIR) reflection and less risk of photo-oxidation. From an ecological perspective, polymers can be recycled via mechanical and chemical recycling, closed-loop cycling, and polymerization of bio-based feedstock. However, post-consumer plastic films do not possess the same optical and energy properties as virgin polymers. The combined benefits of different polymers suggest that these materials could be adopted on a large scale over the long-term.

“…PE mulches are currently prepared from fossil fuels, a feedstock with an uncertain long-term availability whose isolation can potentially harm the environment. The choices available for disposal of PE mulches at the end of their service life are undesirable: illegal burning, stockpiling, or landfilling [3,4,[6][7][8][9][10][11][12]. PE mulch disposal is exacerbated by its frequent embrittlement due to exposure to sunlight and weathering, producing debris that is poorly biodegradable, difficult, laborious, and/or expensive to retrieve, and serves as an environmental hazard to animals and fish via ingestion or entanglement [3,13].…”

Soil Degradation of Polylactic Acid/Polyhydroxyalkanoate-Based Nonwoven Mulches

et al. 2015

The soil degradation of fully biobased agricultural mulches prepared from polylactic acid (PLA) and blends of PLA and poly3-hydroxybutyrate-co-4-hydroxybutyrate (polyhydroxyalkanoate, or PHA) using nonwoven textile technology was compared to that of a commercial biodegradable mulch film, BioTelo (Dubois Agrinovation, Waterford, Canada). The addition of PHA to PLA to the feedstock blend produced nonwovens that possessed lower tensile strength and molecular weight and increased the average fiber diameter of mulches. A meltblown (MB) nonwoven mulch prepared from a PLA-PHA 72/28 w/w blend underwent the greatest degradation, achieving a 78 % loss of tensile strength and a 25.9 % decrease of weight-averaged molecular weight during 10 and 30 week of soil burial, respectively. The mass fraction of PHA decreased during soil burial, suggesting the preferential microbial assimilation of PHA over PLA. BioTelo underwent a 29 % loss of tensile strength but no appreciable change of molecular weight for its chloroform-soluble components. In contrast, spunbond (SB) PLA mulches did not undergo any appreciable degradation during the 30 week soil burial studies. The results suggest that the MB-PLA
