“…Biogas is recognized worldwide as a highly valuable renewable energy and it is produced and used extensively. In the ongoing search for new types of suitable feedstock, agricultural wastes and by-products such as manure and straw are receiving 3 more attention (Chen et al, 2014;Ribeiro and Raiher, 2013). However, the increased desire to put agricultural waste biomass to more complete use is not due to the demand for biogas production alone, but can be ascribed to the prosperous bio-based economy in general.…”

Effects of selected process conditions on the stability of hydrochar in low-carbon sandy soil

et al. 2016

Biochars have been found to enhance soil properties and to reduce atmospheric greenhouse gases due to their stable carbon fractions. It is known that stable carbon fractions of pyrolysis-derived biochars usually exhibit mean residence times (MRT) of at least several hundred years. However, only a few studies exist on the stability of hydrochars, which are produced by hydrothermal carbonization (HTC). This study examined the influence of two feedstock materials, straw digestate and poplar, and several processing and treatment parameters (carbonization temperature, washing of hydrochars and recirculating of process water) on the stability of hydrochars in a carbon-poor sandy soil. The results show that HTC leads to a product of variable carbon fractions with different stabilities as reflected in the different rates of CO2-C release from soil incubations within the first weeks. The carbon pool of the hydrochars 2 could be classified into a readily available and a fast-cycling decade-scale fraction. No slow-cycling centennial-scale carbon fraction was observed in this 120-day study. Moreover, a high reaction temperature and enhanced recirculation rate of process liquor lead to higher stability of the hydrochars. Based on the two-pool model, the more stable carbon had an MRT of 4-15 y depending on the reaction temperature and an MRT of 11-14 y for the recirculation of process liquor. The main hypothesis, that this short-term study of 120 days allows a reliable description of the long-term degradability of hydrochars, could not be confirmed.

“…This paper was included in the SLR because cooperatives in Slovenia were based on a similar model to rural condominiums in Brazil. Rural condominiums can be found in the following sectors: agroenergy (Almeida et al , 2017; Ribeiro and Raiher, 2013); pig production (Anjos et al , 2011; Wilkinson et al , 2017); and milk (Kiyota et al , 2012).…”

Purpose The purpose of this paper is to analyze the development of rural warehouses condominiums (or “condos”) as new rural configurations in the Brazilian agribusiness from the perspective of the theory of collective action. Design/methodology/approach A systematic literature review was complemented with multiple case studies based on interviews and direct observation. Content analysis was used to interpret the secondary and primary data. Findings Rural warehouse condos can be characterized as a collective action which is a new business model in Brazilian agribusiness. This new initiative has several advantages: reduction of the warehouse deficit and other logistical bottlenecks; strategic commercialization of production; reduction of logistical costs; inclusion of smallholders in the economy and, consequently, the generation of income for smallholders and their participation in the market. Research limitations/implications The study used a qualitative approach and findings and discussion are inherently interpretative. Social implications Understanding the organization of rural warehouse condos supports the inclusion of smallholding farmers and income generation. This creates a social benefit through rural growth and economic development. Some constraints related to the lack of public policies, specific credit lines in financial institutions, the problem of non-regularized rural areas, lack of transparency and conflicts among the members can limit expansion. Originality/value Rural warehouse condos are expanding mainly in the south region of Brazil, where smallholders are concentrated. In this new configuration, they can engage in an association to obtain several benefits, such as reduced logistics costs, better access to financing and increased bargaining power with suppliers. As this research dealt with a relatively new and poorly studied topic, it contributes to the development of new studies to map innovative warehousing practices.

“…Essa mesma característica sustentável também é notada nos Condomínios de Agroenergia. Formação mais atual encontrada na literatura internacional dentre os tipos de Condomínios, os Condomínios de Agroenergia objetivam gerar bioenergia a partir da união de propriedades rurais vizinhas, que usam o acúmulo do biogás de suínos ou gado (ALMEIDA et al, 2017;RIBEIRO;RAIHER, 2013). Ambos os trabalhos foram estudos desenvolvidos no estado do Paraná, Brasil.…”

A agricultura sofre com intensas mudanças a cada dia, provenientes da esfera econômica, social, política e tecnológica. As organizações rurais necessitam então se transformar para atender a um cenário dinâmico e um mercado cada vez mais exigente e competitivo (BUAINAIN; GARCIA, 2015; BUAINAIN; GARCIA; VIEIRA FILHO, 2018; SAES; SILVEIRA, 2014). É nesse sentido que os Condomínios Rurais ganham destaque. Os Condomínios Rurais são organizações de produtores rurais vizinhos e/ou próximos, que visam desenvolver atividades agrícolas e/ou pecuárias em conjunto, geralmente com o auxílio tecnológico, e proporcionam obter melhores ganhos e benefícios, superar dificuldades no campo e aumentam a competitividade no Agronegócio (FILIPPI, 2017). O tema é relativamente recente, com pouca literatura acadêmica acerca do assunto e pertinente para o Agronegócio. E também exibe pluralidade e
