Quarries renaturation by planting cork oaks and survey with uav

Research aims to provide a strategy to start mitigate the over consumption of fossil energy in buildings and the inter connected over burning of energy fossil sources: methane; oil; coal. All this, through energy efficiency or “passivation” of all buildings in whole districts, quarters, cities using cork, a unique and very highly performing nature-based material. All this is sufficient to think that the post carbon city strategy is really possible. It even seems incredible to think that to mitigate and solve the huge problem of climate change for Europe and Mediterranean region it would be enough to use “simple” cork as natural-based (oil free; chemical free; ffff = free fossil fuel future) insulation panels! One additional innovation, among others, in the strategy above cited, is the production from cork of vegetable sand for mortars, substituting the mineral silica-sand extracted from river sand, crushed stone and stone quarries. One positive consequence of this further innovation is the decrease and fall of mineral sand extraction and the possibility of recovery (= renaturation) of quarries with different approaches and, among them, through terracing of overhanging rock walls and subsequent “naturation” through oak cork tree planting. To perform the important mission of quarry recovery and renaturation, a general quarry survey (not existing at present time) by UAV and an extracted volume valuation are needed and the research provides a first prototype Case Study.
