Background & Policy context
Rice is one of the most important crops worldwide. China is the world’s leading paddy rice producer; the EU also produces around 3 million tonnes/year. Each tonne of rice can produce up to 20 % of rice husk, which is considered agricultural waste. It is mainly disposed by combustion, producing rice husk ash (RHA), which causes respiratory damage to wildlife and humans. To increase rice production, the MSCA-funded VALZEO project aims to recycle RHA to produce composite materials (CM) of hierarchical zeolite modified by metal oxide nanoparticles and metal-organic framework materials. These will be used to remove pollutants from water and as biodiesel production catalysts. VALZEO will also emphasise the training of partners in analytical techniques to characterise these CM and foster novel exploitations.
Objectives
In EU, an average of 3.1 million tons of paddy rice is produced (ca. 450.000 ha). Around 80% of the EU rice production takes place in Italy and Spain, with a further 12% in Greece and Portugal. Globally, 750 million tons of rice husk (RH) are yearly produced, and it is estimated a continuous increase of 1.1% each year. Each ton of rice can produce 20% of RH, that must be eliminated since it accumulates in the environment due to its low degradability. RH generates 18-20% of RHA through a combustion process. The inadequate deposition of RHA pollutes the environment and deteriorates the respiratory system of humans and animals. During RH incineration, the burnt ash can spread into a large area facilitated by air, causing environmental pollution. According to these figures, large volumes of RHAs with low density are becoming a major challenge to the surroundings of dumping environment and dump fill areas.
VALZEO intends to employ RHAs as raw supplies to produce composite materials based on hierarchical zeolites modified by metal oxide nanoparticles (MON) and metal-organic framework (MOF) materials with a double purpose, the removal of pharmaceuticals, pesticides, dyes and microorganisms in water, and the catalytic production of biodiesel.
