This theme considers AIR-POTS and BIODEGRADABLE POTS, exemplified by Superoots® of Caledonian Tree Company Ltd (gb) and Vipot® by Future Power Srl (I) respectively for reasons of enhanced root growth due to air-pruning and the ability of pots to naturally decompose in the soil due to manufacture from biopolymers and other biodegradable materials. These two product typologies demonstrate revolutionary (discontinuous) innovation.
Other plastic AIR-POTS are more rigid with air-spaces in the side walls. Examples demonstrate vertical corrugation and air slots in the side-walls. Another type has burlap side-walls with horizonal air-spaces as the diameter reduces. One final example, is made from a non-rigid porous fabric that can be folded flat and re-utilized. What types are best suited for ornamental horticulture and nursery-stock production?
For BIODEGRADABLE POTS, there are a great many variables to consider. Are they made of natural materials such as peat or bioplastics (biopolymers)? Are they sufficiently rigid for normal handling and mechanized production systems? How does the material perform under irrigation, especially when placed on capillary matting or under ebb-and flow irrigation? To what extent do they naturally biodegrade in the soil and how quickly do they biodegrade when discarded? Finally but not least are they internationally certified (certified as being environmentally friendly e.g. MPS). A look at this theme provides some answers and will raise new questions that address ecological aspects and the circular economy.
