12,000 tons of food waste transformed a barren landscape in Costa Rica

In Costa Rica, 12,000 tons of orange waste transformed a barren landscape into a biodiverse forest, highlighting agricultural waste's potential for ecological restoration and carbon sequestration, though further research is needed.

12,000 tons of food waste transformed a barren landscape in Costa Rica

In Costa Rica, a remarkable transformation occurred when 12,000 tons of orange peels and pulp were dumped onto a barren landscape by an orange juice producer. This area, once a degraded cattle pasture, has since evolved into a vibrant, biodiverse forest over the past two decades. Timothy Treuer, a researcher from Princeton University, led a study published in Restoration Ecology that highlighted the stark contrast between the treated area and an adjacent untreated section. The treated land flourished with a variety of tree species, including those typically found in old-growth forests, while the untreated area remained sparse with only a few species. The study suggests that the organic waste not only improved soil quality but also suppressed invasive grasses, facilitating forest recovery. The findings underscore the potential of agricultural waste to enhance ecosystems and sequester carbon, demonstrating a successful synergy between industry and conservation. However, the study also raises questions about the long-term impacts and the mechanisms behind this ecological success, as further investigation is needed to fully understand the effects of the orange waste on the environment.

- 12,000 tons of orange waste transformed a barren landscape into a lush forest in Costa Rica.

- The treated area showed significant biodiversity compared to the untreated section.

- The study highlights the potential of agricultural waste for ecological restoration and carbon sequestration.

- Further research is needed to understand the long-term impacts and mechanisms of this transformation.

- The project exemplifies a successful collaboration between industry practices and environmental conservation.

I remember reading this in the past https://www.sciencealert.com/how-12-000-tonnes-of-dumped-ora... that came with more pictures to please our eyes!

It is amazing to think that so much of food waste is simply thrown into a landfill when it could actually be used for refertilising soil. but I do know of instances where people have actually bought food waste - including vegetable and fruit waste, from agricultural markets to put into their farms. However this is quite rare.

Something else which is wasted a lot of silt from the bottom of lakes, ponds, rivers etc. Often it is not sold to farms.

However, again, I do know of a single instance when a small reservoir was desilted by farmers in collaboration with the government. The government gave the farmers the permit to take away the silt for free if they made their transport arrangement to take the silt away and also if they worked with the government on the desilting work.

This enabled the government to get the desilting work done for free while the farmers benefited from getting high quality soil for their farms.

An indirect pointer to https://www.popsci.com/food-waste-fertilizer/ and the one thing it doesn't have is a before-and-after photo sequence. It does show the collection process and the peel piles. Thats a lot of peel and pulp.

Restoring the soil removed by wildfires anyone?
