Poplar trees

Another option for a biofuel source in the Northwest is growing poplar trees. Poplar trees can be grown on marginal agricultural land, used to improve water quality, and cleanup chemically polluted sites. Poplar trees grow quickly and can be ready for harvest 2-3 years after planting.


How much biomass is produced in the EU?

Agriculture has a central role among the biomass producing sectors, providing valuable sources for the EU bioeconomy. Each year, an estimated 956 million tonnes (Mt) of agricultural biomass are produced in the European Union. 54% are primary products, such as grains, fruits, roots and tubers. The remaining 46% are residues, such as leaves and stems.

Is biomass a renewable resource?

Biomass. Biomass is commonly cited as a renewable energy source. The term also is used by biologists and ecologists to describe living and dead carbon-based biological material that is part of the environment’s carbon cycle.


What is biomass in plants?

Plant biomass is the weight of plant dry matter production dried to a constant moisture. It is usually measured on a plant or unit of land basis. Total biomass of a plant is closely related to the capacity for carbon assimilation of the plant.


What is biomass in biology?

Biomass refers to the mass of living organisms, including plants, animals, and microorganisms, or, from a biochemical perspective, cellulose, lignin, sugars, fats, and proteins. Biomass includes both the above- and belowground tissues of plants, for example, leaves, twigs, branches, boles, as well as roots of trees and rhizomes …


How does biomass generate electricity?

Biomass combustion to generate electricity is a simple way to produce bioenergy. The lignin in plant biomass has a high energy content for this application. This allows the option of converting the carbohydrate fraction of the biomass to biofuel or biomaterial and burning the residual lignin to generate electricity. The relative value of electricity and liquid fuels will determine the optimal use of the biomass. This may vary regionally and over time being influenced greatly by the price of oil.


Why is biomass used as a fuel?

Biomass has been used as a fuel source ever since humanity learned to make fire and served as the primary source of energy before fossil fuels became common in the twentieth century. Biomass is still the dominant source of energy for one billion of the poorest people. Biofuels are attractive for a number of reasons – plants act as `solar panels’, capture carbon, and store energy. Their large-scale adaptation as energy source for modern industrial societies hinges on the solar utilization efficiency of plants. Plants appear to have similar efficiencies in capturing solar radiation as the most efficient solar panels that can be deployed at large scale, but the plants’ own metabolism combined with the ‘metabolism’ of the infrastructure to produce biofuel from biomass yields a very low solar utilization. The climate vulnerability of biomass as renewable energy source is largely similar to food crops. Slight differences might be expected for different biofuel types. First generation biofuels might be more vulnerable due to constrains on deploying often energy intensive agricultural practices that can offset adverse climate impacts. Second generation biofuels are likely to be more resilient than food crops since their feedstock comes from marginal lands that are more close to natural vegetation.


How does biomass accumulate before genetic limits?

The environmental limits to biomass accumulation come into effect before genetic limits by affecting photosynthesis. This article reviews the environmental regulation of biomass accumulation. First, the major environmental influences, radiation (sunlight), temperature and water, are discussed.


How much of biomass is converted into organic compounds?

About 90% of biomass is derived from the incorporation of carbon into organic compounds via photosynthesis. It is estimated that 200 billion tonnes of CO2 is converted to biomass annually; 40% by marine plankton and 60% by higher plants.


Does biomass require land?

From an economic standpoint, generating a large amount of biomass requires a large amount of land ( Pimentel et al., 2002 ). This is true for all forms of biomass. Indeed, land economics is required for the development of biomass.


What is biomass energy?

Biomass energy can be derived from agricultural and forestry residues or from crops grown specifically for this purpose, i.e., dedicated energy crops.


What are the advantages of trees as biomass crops?

Since one of the attractions of trees as biomass crops is their tolerance for marginal planting sites, breeding or other strategies intended to genetically improve biomass potential may include the targeting of root traits that can facilitate good performance under limiting conditions. One of the most limiting soil nutrients for agriculture worldwide is phosphorus (P). Roots therefore have evolved multiple strategies for acquiring, storing and remobilizing soil P, and it now appears that storage and remobilization of some of that P directly involve cell wall pectins (Zhu et al., 2015; Zhu, Zhu, Zhao, Zheng, & Shen, 2016). Those authors reported that under P-deficiency, ethylene-induced increases in root pectin level correlated with remobilization of cell wall-adsorbed P in rice (O. sativa ). The specific molecular events surrounding either the ethylene-promoted pectin increase or the P release in those roots were not described, but were found to be ABA-sensitive ( Yu, Zhu, Li, Kronzucker, & Shi, 2016 ). Although a mechanism for solubilizing certain P-immobilizing salts by pectin carboxyl groups was proposed, pectin methylesterification was not reported ( Zhu et al., 2016). It may be enlightening that in ripening fruit, ethylene promotes PME activity which in turn exposes carboxyl groups, facilitates access by other hydrolytic enzymes to the pectin matrix, and promotes expansion of middle lamella and tissue softening (Tucker et al., 2017 ).


How often are grasses harvested?

The grass species are harvested annually. Trees that have the ability to grow back after being cut close to the ground may be harvested every 3–8 years, i.e., coppice. Biomass crops may consist of native species traditionally used for energy production, e.g., willow coppicing in Europe.
