“…Gasification is understood as a process of thermal degradation fed by a sub-stoichiometric amount of oxygen to promote the autothermal partial oxidation of the feed, operating at temperatures above 750°C (Vieira et al, 2021). The main product is a synthesis gas and other gaseous components with a calorific value between 4 and 10 MJ/Nm 3 .…”

Environmental issues weigh heavily on international economic relations with demands for stricter environmental regulations for the deforestation of forest areas and the generation of urban solid waste (USW). These demands drive research in the area of USW to reduce the waste volume and to its use in various fields such as power generation. In 2020, the legal milestone of the National Solid Waste Policy (NSWP) in Brazil was updated, opening space for private initiative in the management of systems related to USW. This work aims to carry out a technological prospection on gasification developed in Brazil using translational research and databases from CAPES, Web of Science, and ESPACENET portals to verify research incentives in universities, public and private, from 1984 to 2022. The search strategy first maps the search for dissertations (master's) and theses (doctoral) documents, called non-patented literature on biomass gasification, and it verifies the relationship with the production of articles in the area, and secondly, it correlates with the production of gasification patent documents. Implementation trends and factors that influenced gasification research were analyzed which generated 357 academic documents (thesis and dissertation), petitioners of patent applications and granted patents in Brazil, and academic research that reached society in the format of 189 articles and one patent.

O objetivo do trabalho foi avaliar o desempenho do milho cultivado com diferentes doses de dejeto líquido suíno (DLS), comparado à adubação mineral (NPK) e sem adubação. Foram avaliadas quatros doses de DLS a partir da necessidade da cultura (50%, 100%, 150% e 200%), NPK e sem adubação (testemunha), com cinco repetições para cada tratamento, com delineamento de blocos casualizados em condições de campo. Foram determinadas a produção de matéria seca total (MST), colmos (MSC) e folhas (MSF), os componentes de produtividade comprimento de espigas (CE), número de fileiras de grãos por espiga (NFGE), número de grãos por espiga (NGE) e número de espigas por metro quadrado (NEMQ), a produtividade de grãos (PG) e o índice de colheita (IC) do milho. As doses de 100%, 150% e 200% de DLS se equipararam ao NPK, tanto para produção de MST (média 6.077 kg/ha), quanto para MSC (4.000 kg/ha) e MSF (2.076 kg/ha). O milho fertilizado com 50% de DLS apresentou maior NEMQ (23) se comparado à testemunha (19) e não houve diferença significativa entre as doses de DLS e NPK (média 20,9). A dose 200% DLS se equiparou ao tratamento NPK no NGE (média 412), no NFGE (12,1) e PG (12.674 kg/ha). As doses de DLS 50, 100 e 150% da recomendada não são equivalentes à adubação NPK, reduzindo, respectivamente, 175, 115 e 114% a PG.

Pig slurry doses affect plant growth and corn grain yield ABSTRACT: The aim was to evaluate the performance of corn grown with different doses of pig slurry (PS), compared to mineral fertilization (NPK) and without fertilization. Four doses of PS were evaluated from the need of the crop (50%, 100%, 150% and 200%), NPK and without fertilization (control), five replications each treatment, with a randomized block design under field conditions. The production of total dry matter (DM), stems (DMS) and leaves (DML), yield components ear length (EL), number of rows of grains per ear (NRGE), number of grains per ear (NGE) and number of ears per square meter (NESM), grain yield (GY) and corn harvest index. The doses of 100%, 150% and 200% of PS were equivalent to NPK, both for DM production (mean 6,077 kg/ha), and for DMS (4,000 kg/ha) and DML (2,076 kg/ha). Corn fertilized with 50% PS showed higher NESM (23) compared to the control (19) and there was no significant difference between the doses of PS and NPK (mean 20.9). The 200% PS dose matched the NPK treatment in NGE (mean 412), NRGE (12.1) and GY (12,674 kg/ha). The PS doses of 50, 100 and 150% of the recommended are not equivalent to NPK fertilization, reducing, respectively, 175, 115 and 114% of GY. Keywords: Zea mays; organic fertilization; animal manure; fertilization efficiency.
