Respecting the ecosystem: these are the goals of Jolly Mec
Global warming is caused by serious imbalances in our planet’s eco-systems. The use of renewable energies as an alternative to fossil fuels offers advantages in terms of minimising the greenhouse effect because the use of wind, sun, water, etc. does not involve any combustion; the combustion of biomass is carbon neutral, because plants remove CO2 from the atmosphere by means of photosynthesis, particularly during growth, and convert it back into biomass. Viewed in this light, opting for renewable energy appears to be more than just an alternative. Thanks to the how emission levels, the Jolly-Mec products fully fall within the parameters fixed by the scopes defined in the Kyoto Protocole, the UE climate-energy Agreements 20-20-20 within Year 2020 as well as the European Guidelines for the use of Renewable Energies.
Jolly-Mec products use only entirely renewable and ecological fuels Using wood or its by-products for heating is a sustainable choice because the balance between the CO2 emitted by the wood during combustion and that absorbed by the plant during its life is equal to zero. Minimal emissions The design of the heating fireplaces and heating stoves is geared to reduce the particulate and all the harmful emissions into the atmosphere. The residual gas emissions remain far below the permitted minimum values, in favour of the air that we breathe. Extremely high efficiency: more heat with less fuel. Jolly-Mec heating fireplaces and heating stoves generate complete combustion with efficiency up to 92.74%. A smaller amount of fuel provides more heat, reducing the exploitation of forest reserves to a minimum. Ideal for homes with a low energy consumption. Jolly-Mec heating fireplaces are equipped with a combustion air pipe that can be connected directly with the outside to ensure correct combustion of the wood and not alter the exchange of oxygen in the room.

Combustibles and Definitions
Biomass Biomass is an umbrella term for a wide range of materials of an extremely diverse nature. Biomass covers anything of organic origin, with the exception of plastics and fossil materials. In scientific terms, the term biomass includes all types of material of biological origin, and hence linked with the chemistry of carbon, which derives directly or indirectly from chlorophyll photosynthesis. Chlorophyll photosynthesis Chlorophyll photosynthesis is the biological process by which plants and algae transform sunlight, water and carbon dioxide into carbohydrates and oxygen, according to equation: CO2 + H2O + Solar energy => Cn(H2O) m + O2 Biofuels Agro-forestry biomass refers to organic components obtained from the harvest and processing of agricultural and forestry crops: cuttings, straw, tree-felling and ligneous and cellulose-based residues and by-products, etc. Agro-forestry biomass constitutes a fully fledged fuel (biofuel) capable of supplying energy for residential and industrial applications. Biofuels, on the other hand, are solid, liquid or gaseous fuels derived directly from biomass (e.g. firewood), or obtained through a process of structural transformation of the organic material. The main biofuels are: biodiesel bioethanol wood chip pellets biogas Lastly, bioenergy is any form of useful energy obtained from biofuels. Biomass is the world’s largest source of renewable energy. Pellet Pellets are fuel obtained from dried sawdust compressed into the form of tiny cylinders, without the addition of any additives or other chemical substances. A natural fuel and high-efficiency renewable energy source, pellets have a heating power that, for the same volume, is approximately twice that of firewood. Pellets burn completely, leaving minimal residual ash that can be used as a fertilizer. They are marketed in handy bags of 10/15 kg or loose with a specific truck distribution service. Thanks to the reduced size of their elements, pellets can be managed as a liquid and stored in containers of even considerable, very large, dimensions, located in the most convenient room ensuring a high level of independence. Thanks to the physical properties of lignin, a component of wood, it is not necessary to add any type of binding agent or additive. Pellets can be used both in stoves for heating individual rooms and in boilers for central heating. The raw material of ecological pellets is made up of: 60% natural hardwood 40% natural softwood Good wood pellets have minimal residual humidity, thus yielding high heat value and low emissions. To ensure trouble-free combustion, pellets have to be stored in a dry environment before being placed in the stove. Wood Wood is nowadays definitely the most widely used renewable energy source available and the one with the lowest cost for the same heat production. Firewood heating is therefore the most cost-effective choice. Causes of variation The weight of wood can vary significantly, for the same humidity, as a result of a wide range of factors, chiefly: the species of wood: every species has its own weight per unit of volume (specific weight); the season: atmospheric humidity, and consequently the humidity of wood, changes with the seasons; the distance of the portion of trunk from the base: the closer to the base it is, the higher its weight, due to the compression exerted by the portion of trunk above; age: young trees have lighter wood then old ones; speed of growth the higher the speed of growth, the lighter the wood. How much does weight vary? The quantity of heat developed by the combustion of wood is expressed in terms of heat value. To be more precise, heat value can be: high or low, depending on whether or not the value includes the heat transferred as a result of condensation of the water that vaporises during combustion; absolute or relative, depending on whether it refers to weight or volume; theoretical or effective, depending on whether the material is in the dry state (anhydrous) or contains a given degree of humidity. Definitions heat value (HV): expresses the quantity of heat produced by 1 kg of fuel high heat value (HHV): HV which includes the heat transferred during condensation of the water vaporised during combustion low heat value (LHV): HV which does not include the heat of condensation LHV: LHV expressed per unit of weight absolute theoretical HHV: equates to the LHV of wood in a completely dry state (a state which cannot be achieved in everyday practice) LHV: refers to the heat value of wood in normal conditions of humidity (a little less than 20%) specific weight: expresses the density of a material, i.e. the weight per unit of volume, in this case the weight of 1 cubic metre of wood LHV: represents the heat value of the unit of volume, i.e. the heat generated by 1 cubic metre of wood anhydrous: a state of complete absence of humidity, which is practically unachievable in nature wet weight: the weight of wood in its unprocessed state of humidity.
