Biomass simba imwe yeaya anoshandiswa kupisa maorivhi makomba, zvisaririra zvezvirimwa, nezvimwe. Pamusoro pekukwanisa kushandisa zvisaririra izvi zvisingashandisike, tinogadzira simba rinowedzerwazve. Mumadhorobha mune huwandu hwakawanda hwemarara hunogona kushandiswa kugadzira simba rebiomass.
Ose ari mumapurazi e-agro-maindasitiri, maorivhi, nezvimwe Masara anoshandiswa kugadzira rudzi urwu rwesimba. Zvisinei, mukana we shandisa kukwesha kuburitsa kunyange yakawanda simba. Masango aya anogona kushandiswa senzvimbo yesimba remabhaira emoto?
Shrublands senzvimbo yemafuta
Enerbioscrub chirongwa cheEuropean chakatora nhanho dzacho dzekutanga muna Chikumi 2014 uye chiri kupera izvozvi, rinotevera Zvita, mushure memakore matatu nehafu ebasa. Ichi chiitiko chinotevera chinotora chikamu chinotevera: iyo Ceder Institute yeSoria, kana iyo Center yeKuvandudza Simba Rinovandudzwa (zvinotsamira paCentre for Energy, Environmental and Technological Research -Ciemat- ye Ministry of Economy); iyo Association yeiyo Energy Valorization yeBiomass (Avebiom); makambani Gestamp neBiomasa Forestal; mushandirapamwe weAgresta uye iyo Fabero City Council (León).
Makambani ese aya nemasangano anotsvaga chinangwa chekuziva kana zvichikwanisika kutora mukana wehupfumi pamwe neyakagadzikana nzira matete makuru iyo iriko muIberian Peninsula seinopa mafuta kuchizvarwa chesimba rebiomass.
MuSpain kune mahekita gumi emamirioni eecrubland (isina masango ivhu renzvimbo inokwana 18,5% yemasango ese). Sekureva kweUnited Nations, inenge 20% yenzvimbo dzesango repasi rose iri kukwesha. Yese iyi huwandu hwebiomass iyo isinganyatso kupa kukosha kwezvakatipoteredza kune ecosystems inogona kushandiswa kugadzirwa kwerudzi urwu rwesimba rinowedzerwazve.
Zvinangwa zveprojekti
Pakati pezvinangwa zvepurojekiti yekushandiswa kwemakwenzi sosi yesimba rebiomass yatinowana:
- Tora chikamu mukuvaka yakaderera kabhoni hupfumi uye kuderedza kutsamira pane mafuta. Iri idanho rakanaka kutora mukutarisana neshanduko yesimba inoenda kunogadziriswazve.
- Deredza huwandu hwemafuta anowanikwa mumasango, kudzikisa mikana yemoto wesango.
- Kukurudzira hupfumi hwesango manejimendi, kuratidza kuti inogona kuva imwe nzira inobvumidza kuumba mabasa kumaruwa.
- Wedzera marongero anochengetedza manejimendi anochengetedza uye uite masheya anobatsira epakati pesango.
Iyi purojekiti inoedza kuratidza kuti muchina wekukwesha unokwesha unogona kushandiswa. Uku ndiko kufunga kukuru kweprojekti: tarisa kuti michina inokwanisa here kujekesa nekukohwa biomass panguva imwe chete.
Nenzira iyi, nekuita bvunzo dzinoverengeka, zvinokwanisika kuziva kugona uye kuti mari iyi chirongwa chingave kana chisingave. Rabhoritari uye miedzo yekutyaira yakaitwawo nehukuru hwakaunganidzwa. Zvichienderana nerudzi rwemakwenzi, iwo anoonekwa uye anosarudzika zvinoenderana nemadota emukati, zvicherwa, ukobvu, nezvimwe. Kana mabhushi achinge arongedzwa, anopiswa mumabhaira, ese maindasitiri uye epamba, kuti azive mashandiro uye mashandiro emakwenzi sechinhu chinopa simba remafuta.
Purojekiti mhedziso
Mushure mekuita bvunzo dzakakodzera kuti uzive kugona uye hunhu hweprojekti, mhedziso idzi dzakatorwa:
- Masango ekuchenesa mabasa kuwana mabhushi anogona kuburitsa biomass zviwanikwa.
- Kana zvikaitwa nenzira yakarongeka uye nekuziva shanduko yezvakatikomberedza, kuchenesa kunogona kuitwa nenzira inogadzikana, pasina kukonzera zvinokanganisa pane zvimwe zvinomera nemhuka.
- Iyo biomass inowanikwa kubva mumakwenzi ndeye yepakati-yepamusoro mhando uye inogona kushandiswa senge simba sosi inokwikwidza nemapellets uye matanda machipisi.
- Kuti izvi zviitwe, zvinofanirwa kuti hutongi hweveruzhinji tora iyi nyaya zvakakomba.
- Izvo zvinodikanwa kuti utarisire ruzhinji rwunowanikwa. Naizvozvo, zvinodikanwa kuti uwedzere kuchengetedza silvopastoral uye kushomeka kuwanda kwevanhu. Izvo zvinodikanwa kuti utarisire ruzhinji rwatinarwo tisati tagadzira zvitsva.
