During periods of drought, it is important to use fertilisers that provide plants with the right amount of essential nutrients, namely: nitrogen, potassium and phosphorus. When supplying these essential nutrients, care must be taken not to damage the roots or the soil, whilst ensuring that the soil’s water retention is improved and…
Read moreEnvironmental remediation aims to remove contaminants from the soil, aquifers, surface waters and sediments. From a regulatory perspective, the concept of ‘remediation of contaminated sites’ was introduced by Legislative Decree No. 22 of 5 February 1997 and by Decree No. …
Read moreWhen it comes to vineyards, the speed with which results can be achieved in terms of yield depends heavily on organic and mineral fertilisation. Fertilisation practices should be determined on the basis of the vineyard’s biological cycle, which comprises two phases: the early phase and the second, more mature, phase of adulthood. On average, the…
Read moreThe storage of municipal solid waste in landfill sites for long periods of time entails a number of drawbacks, which could be eliminated or drastically reduced by subjecting the waste to stabilisation processes, which may be followed by thermal compaction or the recovery of the stabilised material. Indeed, when left permanently in landfill, it causes: unpleasant odours that persist for years even after the site has been permanently closed; the presence of…
Read moreOil and Pollution Oil consists of a mixture of various hydrocarbons – substances composed solely of hydrogen and carbon – mixed with water and other impurities. Although this complex of substances is important from an energy perspective, it is extremely harmful to nature and to humans. In fact, it has a significant social and environmental impact…
Read moreLeachate and oily emulsions: what are they? Landfill leachates (liquids resulting from water seeping into waste masses or from the decomposition of waste) have a high concentration of ammoniacal nitrogen and a low content of available carbon despite the high COD (Chemical Oxygen Demand); in this situation…
Read moreAir pollution and purification. During many manufacturing processes, both in industrial and non-industrial settings, gaseous emissions containing pollutants and malodorous substances are produced. The need to limit the presence of pollutants in the air often requires the use of various abatement systems. Indeed, gaseous emissions contain polluting vapours and impurities…
Read moreMicrobiological imbalances and problems with water potability Agricultural soil with a low content of ‘stable’ humus is also microbiologically unbalanced. Beneficial microflora (saprophytes, degraders, mineralisers, etc.) are present in lower-than-normal quantities and are unable to biodegrade crop residues whilst simultaneously introducing…
Read moreThe issue of waste water Protecting the environment from waste water discharges is an issue that is becoming increasingly prominent in Italy. For years, there has been discussion about ways to tackle and prevent this troublesome urban problem. All social, productive and recreational activities make use of…
Read moreComposting: what we’re talking about Composting is the set of complex biological reactions that cause organic matter to decompose under aerobic conditions (i.e. where the biomass is in contact with air). The composting of organic waste involves a range of suitable materials: materials of animal origin (solid and liquid manure, residues from slaughterhouses, the tanning industry, the…
