seaweed-based biomass Articles

Green alternatives to hydrocarbon-based fuels are increasingly derived from recycled waste materials, including paper and packaging materials; residues from other industrial processes, and perhaps most importantly, biomass. Biomass comprises plant waste and plant by-products, and currently represents one of the most exciting avenues of research in the development of alternatives to fossil fuels. ...

In-depth analysis in Minnesota assesses the feasibility and cost-effectiveness of regional biomass generated electricity projects that tap into local feedstocks. The Center for Energy and Environment (CEE) in Minneapolis, Minnesota undertook a multiphase research project to create a framework that communities and legislators can use to determine the feasibility of biomass-generated electricity in ...

Seaweed (fresh, dry) or its products (extracts, composts, soil conditioners) have been long used in agriculture to enhance plant growth and productivity. In this study, we evaluated the effects that seaweed composts at different doses and degree of maturation had on the yield of tomatoes (Licopersicon esculentum Mill. cv. platense) grown on a horticultural soil in northeastern Patagonia. We used ...

We performed a multiple‐pulsed atrazine experiment to measure responses of autotrophic endpoints in outdoor stream mesocosms. The experiment was designed to synthetically simulate worst‐case atrazine chemographs from streams in agricultural catchments to achieve 60‐day mean concentrations of 0 (control), 10, 20, and 30 µg/L, respectively. We dosed triplicate streams with pulses of 0, 50, 100, ...

Calculating forage availability is challenging for managers of grazing systems due to the spatial heterogeneity of swards. Remote sensing applications may help to overcome this problem through estimates of biomass made with reflectance data. The objectives of this study were to (i) estimate herbage mass using an active, on-the-go, ground-based, narrow band sensor to calculate the normalized ...

Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

Making the stuff of bio-based plastics, identifying new value chains in "forest" biorefinery, finding the perfect method for quick drying sludge or pinning down the best kind of pine for making bio-based products. These are the topics of four research projects whose instigators, all Bio4Energy researchers based in northern ...

The capacity to predict time to silking relative to anthesis in maize (Zea mays L.) has important implications for breeding and seed production. We developed a theoretical quantitative framework for simulating the anthesis to silking interval (ASI) based on plant growth and biomass partitioning to the ear. We tested this framework to simulate the progress of silking relative to anthesis in nine ...

Abstract The biomass carbon (C) stock of forests is one of key parameters for the study of regional and global carbon cycles. Literature reviews shows that inventory-based forest C stocks documented for major countries in the middle and high northern latitudes fall within a narrow range of 36–56 Mg C ha−1 with an overall area-weighted mean of 43.6 Mg C ha−1. These estimates are ...

BC Bioenergy Network ("BCBN"), a provincially-funded leader in the growing bioenergy sector in British Columbia and the Wood Pellet Association of Canada ("WPAC"), have released a report that documents Canada's contribution to the EU's renewable energy targets. The study modeled forest carbon dynamics and determined that the production of energy from sustainable solid biomass rapidly mitigates ...

In recent years, the use of agrochemicals has increased because they are essential for profitable agricultural production. Herbicides are heavily demanded compounds and among these, the most marketed are 2,4-D, atrazine and acetochlor. They have characteristics that can cause problems to humans and the environment. Therefore, it is necessary to design systems that can reduce these compounds to ...

Biosorption is an effective method for removing heavy metals from effluent. This work mainly aimed to evaluate the adsorption performance of the widely cultivated novel mushroom, Pleurotus eryngii, for the removal of Cu(II) from single aqueous solutions. Kinetics and equilibria were obtained using a batch technique. The sorption kinetics follows the pseudo-second-order model, whereas the ...

The surface-flow constructed wetland (CW) located in Nonsan City, South Korea, and constructed as the final stage of a piggery wastewater treatment plant that aims to treat high nutrient content effluent during dry days and stormwater runoff during wet days was monitored from October 2008 to November 2011. This research investigated the seasonal nutrient uptake of plant biomass in the CW and ...

In every Greek island there is at least one town with more than 20,000 inhabitants. Several smaller towns and villages range from a few hundreds to a few thousands in population. Usually in the larger towns there are sewage treatment facilities providing at least secondary treatment of wastewater. In most cases the effluent produced is drained to the sea and the sludge is dumped in landfills. In ...

Pearl millet [Pennisetum glaucum (L.) R. Br.] single cross hybrids, bred from high-yielding parental lines in favorable environments, are not well adapted to northwest India's arid zone. The objectives of these experiments were (i) to measure grain and stover yield heterosis in testcrosses of six landrace-based restorer populations and (ii) to understand how heterosis for biomass and harvest ...

A research group from Michigan State University (Department of Plant Biology) is using the UniSpec-DC to analyze biomass dynamics and changes in species composition across a California grassland system, as they relate to management techniques including prescribed burning, prescribed grazing, and reseeding of native grasses. They are interested in enhancing the understanding of grassland dynamics ...

Water recycling is an effective way to reduce water consumption in the industrialization of microalgae-based biomass/bioenergy production. The soluble algal products (SAP) which inhibit the microalgae growth will accumulate in the recycled water. Therefore, the ozone oxidation treatment of SAP produced by Scenedesmus sp. LX1 was studied to reduce the inhibition of SAP. The experimental ...

Duckweed offers the promise of a co-benefit culture combining water purification with biomass production. Acinetobacter calcoaceticus P23 is a plant growth-promoting bacterium isolated from a duckweed, Lemna aequinoctialis. This study quantified its growth-promoting effect on three duckweeds (L. aoukikusa, L. minor, and Spirodela ...
