“…Thus far, published articles on the mechanical properties of biodegradable seedling pots are considered limited. The tensile strength of three selected biodegradable seedling plug-trays made from peat moss, wood fibre, and cow manure was in the range of 1.0–2.0 MPa [ 15 ], which is lower compared to the optimum tensile strength found in this study.…”

“…Some of the known biocontainers are CowPots (East Canaan, CT, USA) made of composted cow manure, compressed and held together with a binder; Jiffy pots (Jiffy Products, Kristiansand, Norway) are made from peat and paper fiber; and paper containers (Western Pulp Products, Corvallis, OR, USA, and Kord Products, Lugoff, SC, USA) are made from paper pulp with a binder [ 10 ]. Furthermore, the tensile strength of three selected biodegradable seedling plug-trays made from peat moss, wood fibre, and cow manure were in the range of 1.0–2.0 MPa [ 15 ]. Biodegradable pots made from recycled wastes of tomato (90%) and hemp fibers (10%) with sodium alginate as binder demonstrated a tensile strength of 1.20 MPa [ 16 ].…”

This study evaluates the efficacy of using textile waste blended with paper waste to form biodegradable seedling pots. A bio-composite blend of cotton (20% cotton, 40% newspaper, and 40% corrugated cardboard) and polycotton (20% polycotton, 40% newspaper, and 40% corrugated cardboard) with an optimum strength was formed into seedling pots. The appreciated seedling pots (untreated blends of cotton and polycotton) were compared with the commercial pots (cardboard seed starter pot and Jiffy pot) in terms of mechanical properties (tensile strength and compressive strength), biodegradability (soil burial test and anaerobic digestion), and seed germination. The untreated blends of cotton and polycotton pots demonstrated a comparable optimum strength, while the Jiffy pot and cardboard seed starter pot obtained the least tensile and compressive strengths, respectively. The anaerobic biodegradability assay suggests that the cotton blend pot, polycotton blend pot, and cardboard seed starter pot can degrade anaerobically because of high biogas and methane generation potential. A 100% seed germination was observed from the four seedling pots tested. Thus, the results demonstrate the efficacy of utilizing textile waste and paper waste to develop seedling pots with desirable strength and biodegradability compared to the commercial pots.

“…Plug trays help to grow seedlings faster after sowing and before transplanting to the soil [ 35 ]. The advantage of plug seedling is the cohesion achieved between plant roots and the soil, whereby roots are effectively protected from damage during transplanting [ 36 ]. Early sporophyte seedlings form very thin roots and are vulnerable to minor damage.…”

Bracken fern (Pteridium aquilinum var. latiusculum (Desv.) Underw. ex A. Heller) has long been grown industrially in South Korea. Conventional propagation methods, including planting rhizomes and in vitro seedling culture, are labor intensive and expensive, and thus not commercially suitable. We aimed to develop a system to produce synthetic seeds using fern spores (SFS). Synthetic seeds were prepared by mixing bracken spores and alginate matrix. Spore germination and gametophyte and sporophyte growth and development from SFS proceeded normally. Spore density affected gametophyte and sporophyte numbers. SFS prepared using cold (4 °C) long-term storage spores (even 7-year-old spores) could effectively form sporophytes. The highest germination was observed at 25 °C. Soaking-treated SFS successfully formed sporophytes, even after 30 days of storage at 4 °C; indeed, sporophytes formed even after five days of storage at 25 °C during transport conditions. SFS were sown in plug trays for commercial use. Young sporophytes grown from plug seedlings were greenhouse cultivated, and transplanting within eight weeks was effective for root growth and growing-point formation. Developing synthetic seeds is a feasible solution for facilitating efficient transport and the handling of small-sized fern spores; furthermore, this SFS technology provides the basis for fern seedling culture and fern spore industrialization.

“…Moreover, biodegradable pots (biopots) are not harmful to the plant roots because they can be transferred directly from the nursery to the plantation without disassembly [3][4][5][6][7][8][9][10]. Various high fiber biomass, such as coconut frond and fiber, wood fiber, paddy husk and straw, mushroom substrates, banana peel, and also cow manure have been studied as reinforcing substances in the production of biopots [3,4,[11][12][13][14][15]. Oil palm empty fruit bunch (OPEFB) is one of the interesting and potential material for biopot reinforcement due to its high content of fibers (72%).…”

Efforts to overcome the problem of agroplastic waste (in the form of pots, polybags, and other planting containers) continue to be studied. This research investigated the use of oil palm empty fruit bunch (OPEFB) and sodium alginate in the production process of biodegradable pots. This study also investigated the comprehensive features of biodegradable pots which included physical, mechanical, structural (chemical), and morphological properties. Physical and mechanical characterization showed that the moisture content, specific gravity, water absorption, ultimate tensile strength (UTS), and elongation at break of the examined biodegradable pots increased with increasing sodium alginate content. Biopot-3 with 15% sodium alginate exhibited the highest UTS at 1.29 MPa and elongation at break at 6.77%. FTIR spectra in the 400-4000 cm -1 region showed that all examined biodegradable pots exhibited identical spectra which most of the peaks showed the characteristics of cellulose, hemicellulose, and alginate. While, XRD patterns showed that the biodegradable pot material has an amorphous structure with 2θ angles being 21.69º, 22.01º, HIGHLIGHTS• Oil palm empty fruit bunch is sufficient to be used as reinforcement on the biopot production.• Application of sodium alginate deliver a positive effect on the biopot's mechanical properties.• Properties of the developed biopot indicate the possibility to substitute the plastic pot use.
