Methods of separating renewable materials, such as lipids, from microorganisms, such as oleaginous yeasts, may include conditioning cell walls of the microorganisms to form, open or enlarge pores, and removing at least a portion of the renewable material through the pores. These methods may result in delipidated microorganisms with cell walls that are substantially intact and with mesopores. These delipidated microorganisms may be used to produce biofuels.

A polyether polyol based on renewable materials is obtained by the in situ production of a polyether from a hydroxyl group-containing vegetable oil, at least one alkylene oxide and a low molecular weight polyol having at least 2 hydroxyl groups. The polyol is produced by introducing the hydroxyl group-containing vegetable oil, a catalyst and an alkylene oxide to a reactor and initiating the alkoxylation reaction. After the alkoxylation reaction has begun but before the reaction has been 20% completed, the low molecular weight polyol having at least 2 hydroxyl groups is continuously introduced into the reactor. After the in situ made polyether polyol product having the desired molecular weight has been formed, the in situ made polyether polyol is removed from the reactor. These polyether polyols are particularly suitable for the production of flexible polyurethane foams.

A polymer, optionally made from renewable sources, comprising a specific chemical structure that is a result of the polymerization of α-hydroxycarbonyl compounds (alpha-hydroxycarbonyl compounds), particularly α-hydroxyaldehydes (alpha-hydroxyaldehydes) and α-hydroxyketones (alpha-hydroxyketones), or glycolaldehyde. A method of polymerization, the method comprising the step of reacting trimethylsilyl trifluoromethanesulfonate with the cyclic dimer of one or more α-hydroxycarbonyl compounds. A method of making said polymer, the method comprising dehydrating a cyclic dimer of one or more α-hydroxycarbonyl compounds.

The present invention relates to a polymer composition comprising polylactide and, based on the weight of this polymer, from 17 to 25 wt % of a chain modifier, from 30 to 55 wt % of an elastomeric polymer and from 20 to 45 wt % of a plasticizer. The invention also relates to the method of preparing said composition as well as to the method of manufacturing an article starting from said composition and the article per se.

A thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density is provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive to form a precursor material in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor material is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). This creates a network of voids located adjacent to the discrete domains, which as a result of their proximal location, can form a bridge between the boundaries of the voids and act as internal structural “hinges” that help stabilize the network and increase its ability to dissipate energy. The present inventors have also discovered that the voids can be distributed in a substantially homogeneous fashion throughout the composition.

The power of DC electrical sources is combined onto a DC buss, such that each source behaves independently from any other source attached to the buss. In one embodiment, a converter module is attached to each of a plurality of solar photovoltaic panels and its output is attached in a parallel manner to a common buss that forms the input to a DC AC inverter. The converter module includes a Maximum Power Point Tracking component that matches the output impedance of the panels to the input impedance of the converter module. The converter also includes a communication component that provides parametric data and identification to a central inverter. Data generated by each converter module is transmitted over the power line or by wireless means and is collected at the inverter and forwarded to a data collection and reporting system.

System and method for sustainable economic development which includes hydrogen extracted from substances, for example, sea water, industrial waste water, agricultural waste water, sewage, and landfill waste water. The hydrogen extraction is accomplished by thermal dissociation, electrical dissociation, optical dissociation, and magnetic dissociation. The hydrogen extraction further includes operation in conjunction with energy addition from renewable resources, for example, solar, wind, moving water, geothermal, or biomass resources.

A process for producing a renewable hydrocarbon fuel. The process can include providing a feed including a lignocellulosic material to a pyrolysis zone to produce a stream including a pyrolysis oil, providing the pyrolysis oil stream to a refining zone producing a refined stream, providing at least a portion of the refined stream to a reforming zone producing a stream including hydrogen, providing at least a portion of the hydrogen stream to the refining zone; and recovering the renewable hydrocarbon fuel from the refined stream.

Techniques, systems, apparatus and material are described for generating renewable energy from biomass waste while sequestering carbon. In one aspect, a method performed by a reactor to dissociate raw biomass waste into a renewable source energy or a carbon byproduct or both includes receiving the raw biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction. Waste heat is recovered from an external heat source to heat the received raw biomass waste. The heated raw biomass waste is dissociated to produce the renewable fuel, carbon byproduct or both. The dissociating includes compacting the heated raw biomass waste, generating heat from an internal heat source, and applying the generated heat to the compacted biomass waste under pressure.
