Eco-friendly Hostel in QueposOnly one hostel Quepos Costa Rica is practicing sustainable living techniques. Owners at Villas Jacquelina, eco-friendly Hostel in Quepos Costa Rica, built this vericomposting structure that is home to hundreds of worms. This composting tower was made using all recycled materials, ( recycled plastic buckets, recycled metal wiring) and generates highly concentrated purely organic fertilizer for the Villas rooftop garden and all other plants. The way it works: At this hostel in Quepos, buckets are filled with the stuff that the worms love to eat. (grass, cardboard, leafs, compost, and dirt). All the worms are put into the bottom bucket of mixture. The worms over time eat everything in the bottom bucket and turn all the compost, grass, and leaves into "worm castings" (fertilizer). When they finish turning the food in the bottom bucket into fertilizer they move up to the second highest bucket to eat the next batch of food. We then remove the bottom bucket (which is now fertilizer), remove the fertilizer and refill the bucket with worm food. The fresh bucket of worm food is put on the top of the stack and is ready to attract the worms from below. One of the key attributes of our vericompost stack is the availability of oxygen. If the buckets are not well oxygenated, the bucket contents can change consistency and the worms can die. In order to keep the buckets well oxygenated, we have drilled small holes into each worm bucket. We have also ran a piece of PVC down the middle of each bucket to allow central entry of oxygen. The PVC has many holes in it and therefore breaths oxygen to the center of each bucket. Click here to learn more about the sustainable techniques used by this eco-friendly hostel in Quepos. Here is what wikipedia has to say about vermicomposting:
Vermicompost is the product or process of compostingusing various worms, usually re wigglers, white worms, and other earthworms to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast. Vermicast, also called worm castings, worm humus or worm manure, is the end-product of the breakdown of organic matterby an earthworm. These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than do organic materials before vermicomposting.As a fertilizer Vermicompost can be mixed directly into the soil, or seeped in water and made into a worm tea by mixing some vermicompost in water, bubbling in oxygen with a small air pump, and steeping for a number of hours or days. The microbial activity of the compost is greater if it is aerated during this period. The resulting liquid is used as a fertilizer or sprayed on the plants. The dark brown waste liquid, or leachate , that drains into the bottom of some vermicomposting systems as water-rich foods break down, is best applied back to the bin when added moisture is needed due to the possibility of phytotoxin content and organic acids that may be toxic to plants. The pH, nutrient, and microbial content of these fertilizers varies upon the inputs fed to worms. Pulverized limestone, or calcium carbonate can be added to the system to raise the pH.
