The efficient and sustainable disposal or value addition of waste plastic has major importance. Recent studies on the char produced via pyrolysis have demonstrated that it is a valuable additive with multiple applications ranging from soil water amendment, improving agricultural yield, supercapacitors, fuel cells, in support/catalysts, chemistry, carbon sequestration. Thus, essential to ensure quality efficacy biochar any combination feedstock process maximum benefits. However, very few focussed techniques parameters optimize yield. This study aims review techniques, reactor types, identify could enhance generation co-pyrolysis biomass feedstock. discusses production mechanism technology, types. followed by factors can be used production. Accordingly, identified temperature, heating rate, bed height type, residence time, pressure, type blending ratio as determinants had highest influence stability, content biochar. Most importantly, technology readiness level (TRL) pyrolysis, discussed. necessitates further these ascertain accuracy optimization achieved configuring processes

Biochar and Its Broad Impacts in Soil Quality and Fertility, Nutrient Leaching and Crop Productivity: A Review

Agronomy, Год журнала: 2021, Номер 11(5), С. 993 - 993

Опубликована: Май 17, 2021

Biochar is gaining significant attention due to its potential for carbon (C) sequestration, improvement of soil health, fertility enhancement, and crop productivity quality. In this review, we discuss the most common available techniques biochar production, main physiochemical properties biochar, effects on including physical, chemical, biological parameters quality fertility, nutrient leaching, salt stress, addition, impacts addition salt-affected heavy metal contaminated soils were also reviewed. An ample body literature supports idea that amended with has a high increase concomitant in structure, use efficiency (NUE), aeration, porosity, water-holding capacity (WHC), among other amendments. However, increases biochar-amended are frequently reported coarse-textured sandy compared fine-textured fertile soils. effect microbial community composition abundance. The negative polluted have plant growth yield components such as aggregation stability can be ameliorated by application biochar. Moreover, positive been observed when was applied organic inorganic amendments fertilizers. decrease nitrogen (N) leaching volatilization well NUE. some biomass activity reported. There evidence sorb retain pesticides long periods time, which may result weed infestation control cost.

Biochar surface functional groups as affected by biomass feedstock, biochar composition and pyrolysis temperature

Carbon Resources Conversion, Год журнала: 2021, Номер 4, С. 36 - 46

Опубликована: Янв. 1, 2021

By testing 92 different biochars, this study had the objective to determine relations between simple physico-chemical characteristics of biochar (elemental composition, ash fraction, specific surface area, process parameters) and infrared sorption revealing presence functional groups. The results Diffusive Reflection Fourier Transformation Infrared Spectroscopy were statistically analyzed with multiple linear regression techniques Principal Component Analysis (PCA) characterization parameters as model inputs. dominant affecting group signals pyrolysis temperature, H/C-ratio area fraction. Regression models able explain 60–90% data variance for peaks in DRIFTS-spectra. application PCA could further reduce input three main factors explaining 70.8% total variance. Biplots first two showed similarity spectra biochars produced at 300 450 °C, whereas a temperature 600 °C lead partial 750 nearly complete loss

Prediction of Soil Heavy Metal Immobilization by Biochar Using Machine Learning

Environmental Science & Technology, Год журнала: 2022, Номер 56(7), С. 4187 - 4198

Опубликована: Март 15, 2022

Biochar application is a promising strategy for the remediation of contaminated soil, while ensuring sustainable waste management. heavy metal (HM)-contaminated soil primarily depends on properties biochar, and HM. The optimum conditions HM immobilization in biochar-amended soils are site-specific vary among studies. Therefore, generalized approach to predict efficiency required. This study employs machine learning (ML) approaches biochar soils. nitrogen content (0.3–25.9%) rate (0.5–10%) were two most significant features affecting immobilization. Causal analysis showed that empirical categories efficiency, order importance, > experimental properties. this presents new insights into effects can help determine enhanced
