Chlorophyll – film is a new type of mulching film for small-holding salad farms. By extracting from salad wastes from farm, Chlorophyll – film is able to absorb more heat from sun lighting during summer season. Combined with the pest trap, the local high heat area works as the target for pest control in an organic way.

The project Chlorophyll-film aimed at exploring how new materials and new methods can disrupt the farming activities in small-holding salad farms in a sustainable way. The project developed a sustainable solution combining a pest-control material, farming planning, and corresponding service to achieve a new salad farming concept.

The project took a disruptive innovation route ideating and testing around the new bio material from a real application perspective. The key innovation part of the project Chlorophyll-film is the new biodegradable material originated from farm waste, trying to meet the profits of all parties from farmers to manufacturers directly and indirectly. The new materials provide an unconventional way to control pest in salad farming, and to reduce the investments on pesticides. The innovative way to combine the new material with traditional reusable mulching film encourages farmers to farm in a more sustainable way. The farming planning of mulching film explores new possibilities for next generation farmers to reconsider scientific farming. A few technology demonstrators were developed in the project, which steered the project towards a commercially- driven brief.

The whole concept would be using the extraction of chlorophyll from salad waste to make a special film layer for pest control, by raising the film temperature largely.

The design of using chlorophyll for pest control is illustrated. The yellow part works to attract pest while the green part works for control pest.

The film with pest control function are designed with two main versions to meet the farming requirements under different circumstance.

Compared to the traditional mulching film that no one is responsible for film recycle. The chlorophyll-film company would be able to collect the film back with the package and recycle it.
