What do supermarkets do with their products when the expiry date has been reached? Surprisingly, there are only a limited amount of options. Belgian retailer Colruyt has found a sustainable angle: they convert it to green power.
Pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon dioxide. Depending on the thermal environment and the final temperature, pyrolysis will yield mainly biochar at low temperatures, less than 450 0C, when the heating rate is quite slow, and mainly gases at high temperatures, greater than 800 0C, with rapid heating rates. At an intermediate temperature and under relatively high heating rates, the main product is bio-oil.
Does Jatropha risk a backlash from public opinion? Jatropha proponents have justifiably been promoting its benefits as a sustainable source of oil crops for years, but from the agro-business side it seems to be evolving in the opposite way: monoculture, hurting biodiversity, causing deforestation and competing for land with food crops.
The aviation industry produces only about one-ninth as much carbon dioxide as motor vehicles do. However, environmentalists are vocal about emissions from aviation, because they tend to go into the upper atmosphere, where some scientists say the impact is greater.
Biomass can play a major role in helping reduce reliance on fossil fuels by making use of efficient thermo-chemical conversion technologies. In addition, the increased utilization of biomass-based fuels will be instrumental in safeguarding the environment, generation of new job opportunities, sustainable development and health improvements in rural areas.
Middle Eastern oil sheiks move over. There's a new kid on the energy block!
The livestock industry is a vitally important contributor to the economy of any country, regardless of the degree of industrialization. Animal manure is a valuable source of renewable energy; additionally, it has soil enhancement properties.
Generally, the greater the economic prosperity and the higher percentage of urban population, the greater the amount of solid waste produced. Reduction in the volume and mass of solid waste is a crucial issue especially in the light of limited availability of final disposal sites in many parts of the world.
We're making biomass briquettes using forest residues or agro-waste which include a wide-range of residues: dry leaves, grass, unwarranted weeds, (Lantana) forest residue, cow dung, sawdust from local sawmills, and highly inflammable pine needles that cause forest fires. These briquettes are then supplied to brick kilns manufacturers, boiler operators for steam generation, and food processing industries that use coal for heating purposes. The low cost and guaranteed availability of the densified biomass is the main motivator for the clients to switch to the clean energy alternative.
Denmark has installed a number of garbage plants that take trash and make it into energy. These plants are at the forefront of waste/energy technology.
GE announced today that they have just joined an $8 million funding round for California-based start-up CoolPlanet, which is developing a unique thermal/mechanical processor technology that converts low-grade biomass - such as grass, woodchips, crop residue and algae — into high-grade fuel. With this recent upsurge in funding, can biofuels be a viable reality…
On average we throw away 2.7kgs of food per person, per week. Now, a leading environmental solutions company has developed a technology to convert this waste stream into green renewable energy.
Renewable energy technology is powering farms and small communities while controlling organic waste volume and odor.
