A b s t r a c t. Digestate from biogas plants can play important role in agriculture by providing nutrients, improving soil structure and reducing the use of mineral fertilizers. Still, less is known about greenhouse gas emissions from soil during and after digestate application. The aim of the study was to estimate the emissions of carbon dioxide (CO 2 ) and methane (CH 4 ) from a field which was fertilized with digestate. The gas fluxes were measured with the eddy covariance system. Each day, the eddy covariance system was installed in various places of the field, depending on the dominant wind direction, so that each time the results were obtained from an area where the digestate was distributed. The results showed the relatively low impact of the studied gases emissions on total greenhouse gas emissions from agriculture. Maximum values of the CO 2 and CH 4 fluxes, 79.62 and 3.049 µmol s -1 m -2

The article proves that application of biogas installations as an alternative method to receive energy is efficient; it shows that there are certain difficulties in biogas production. The use of biogas installations in Russia is a quite new energy production method. Despite indisputable benefits of their application, there are also problems connected the half-baked process of their application, rather big investments and, as a result, not a short payback period. There are no federal methods of rate calculations for biogas energy. Besides the fact that electric power and heat received from biogas processing are very economical for enterprises, this production is ecologically friendly; it prevents methane emission in the atmosphere, which is an important thing. One more great benefit is the associated products received in the course waste conversion. The article also points out special features of biogas and biogas installations from the point of view of ecology and efficiency. We have described the project how to use a biogas installation, which characteristics considerably exceed its analogs.

RESUMO -O composto metalorgânico Zn-ZIF-8 foi sintetizado e impregnado em tecido de algodão para aplicação no processo de captura de metano (CH4) devido sua capacidade de adsorção e armazenamento de gases. Como o CH4 aparece como um dos principais gases responsáveis pelo efeito estufa, reduzir sua emissão é de fundamental importância no controle dos problemas ambientais. A área específica da Zn-SIF-8 impregnada no tecido foi de 574,3 m 2 g -1 (BET) e área de microporos (t-Plot) de 553,9 m 2 g -1 . A fixação do material no tecido foi confirmada por DRX do tecido, da MOF e da MOF impregnada no tecido. Portanto neste trabalho foi avaliado a eficiência da Zn-ZIF em tecido, a 25 ºC e 1 bar, no processo de captura de metano sendo adsorvido 680 cm 3 do gás por área (m 2 ) do tecido. INTRODUÇÃOSegundo Baldé et al. (2016), o potencial de poluição do metano (CH4) faz desse gás um dos principais responsáveis pelo efeito estufa. Com isso pesquisadores de diferentes áreas buscam alternativas que visam diminuir a emissão desse gás e consequentemente os impactos ambientais gerados por ele. Os autores Anbia, Hoseini e Sheykhi (2012) apresentam as estruturas metalorgânicas como importante alternativa de controle ambiental devido sua excelente capacidade no processo de adsorção de metano.Compostos metalorgânicos ou metal-organic frameworks (MOFs), são estruturas cristalinas híbridas porosas, formadas por metais conectados a ligantes orgânicos, que podem ser em uma, duas ou três dimensões (Cliffe et al., 2014). Segundo Wu et al. (2013), as MOFs apresentam grande área específica, volume e uniformidade de diâmetro de poros, além de vários sítios ativos para funcionalização pós-síntese (FPS). De acordo com Rosseinsky (2003), as características estruturais desse material garantem potencial capacidade de adsorver e armazenar gases como, por exemplo, o CH4.As zeolitic imidazolate frameworks (ZIFs) é um subgrupo das MOFs, que devido sua elevada estabilidade química e térmica é preferencialmente aplicada na captura de gases (Yin et al., 2015). De acordo com Wang et al. (2016), Zn-ZIF são ZIFs que possuem como centro metálico o metal zinco conectado a ligantes orgânicos imidazólicos, e apresentam um microcristal com tamanho médio de 172 nm, volume do microporo de 0,4 cm³g -1 e área
