Sugarcane waste pots boost pepper yields and skip the plastic

Every plastic nursery pot you've ever bought will outlast your garden by centuries, but these sugarcane-based pots feed the soil as they decompose.
Scientists built plant pots out of sugarcane leftovers from sugar production, then treated the fibers with a mild chemical wash to help them bond together more tightly. When they grew peppers in these pots inside a greenhouse, the plants produced 13% more fruit than plants in conventional containers. As the pots break down in the soil, they release carbon and plant nutrients rather than leaving plastic fragments behind.
Key Findings
Pepper plants grown in treated biocomposite pots yielded 13% more fruit than control plants.
SEM-EDX analysis showed pots contained 34.5-54.4% carbon and detectable plant nutrients, confirming nutrient-recycling potential as the material degrades.
Alkaline pretreatment with sodium hydroxide improved fiber bonding by reducing lignin and hemicellulose, verified by FTIR and XRD spectroscopy.

Researchers made biodegradable plant pots from sugarcane waste and tested them in greenhouse trials. Plants grown in these pots produced 13% more peppers, and the pots break down into the soil, releasing nutrients instead of leaving plastic behind.

Gene editing removes 97% of celiac-triggering proteins from bread wheat
It could mean that people with celiac disease — roughly 1 in 100 worldwide — may one day safely eat bread made from real wheat, without sacrificing the taste...
Sugarcane or sugar cane is a species of tall, perennial grass that is used for sugar production. The plants are 2–7 m tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the stalk internodes. Sugarcanes belong to the grass family, Poaceae, an economically impor...
