AN ANSWER TO CLIMATE CHANGE
Although energy efficiency and renewable energy are on long term the
most sustainable solutions, both for the safety of resources and for the
environment, this reduction will not be possible if other solutions such as
capture and storage technology are not used. More than that, it is expected that
this technology will play a key-role in the global strategy against the effects of
climate change.

Setting emission sources, their values, substances that are
discharged, the effect of substances on the environment, are issues before the
establishment of measures to be taken to reduce or eliminate pollutant
emissions. Determination of pollutant emissions and assessing the degree of
pollution in a uniform manner in all European Community countries must use a
single method of calculating the level of pollution. Monitoring of environmental
factors on agglomeration is important because it highlights the level of pollution
in a city, established source of pollution and may recommend appropriate
measures for its reduction.

from human activity. CO2 emitted quantity must be reduced and even stopped
regarding to the global treaties. Carbon dioxide concentration and recuperation
from thermal installation emitted gazes is the first major step in carbon dioxide

RECYCLING INDUSTRIAL WASTEWATER WITH HEAVY

Removing heavy metal ions from industrial wastewater by ion
exchange is based on the properties of the ion – cationic exchanger to change
their own captions with those from the wastewater. The purification technology
by ion exchange consists of replacing the polluting ion from the used water with
another ion, which is much less polluted, or which results in obtaining an
insoluble chemical compound or one that is easier to remove. The ion
exchange between the zeolite and the heavy metal ions is a type of adsorption
-chemical reaction – denuding, and the transfer through the zeolite pores
determines the process. The process is favorite by temperature increase, by pH
increase of the solution from the wastewater, the heavy metal ion concentration
increase of the initial solution, the quantitative increase of the volcanic tuff.

CONSIDERATIONS REGARDING THE IMPACT OF

The soil crust is formatted as a result of excessive humidity absorbed
by soil, which exceed its capacity of retaining water.
This leads to additional expense for the works, which provide remedy.
In conditions of irrigation these are performed after each watering. The
sprinkling watering has a more negative effect than in furrow watering. Soils do
not form this crust contain sand 60-80 %, dust 10-20 % and clay 5-10 %.
The main factor, which generates formation of crust on the cultivated
land, is the lack of soil particle formations stable in water and big amounts of
clay colloidal particles.

method of recycling, with low environmental impact. A method that meets these
conditions and witch does not require any washing and separation of polymers
and/or waste materials based on these polymers, is the chemical recycling by
“pyrolysis”. By pyrolysis process, wastes are converted into liquid fractions
close to commercial fuels, in certain reaction conditions. The results obtained
