UPM creates renewable and responsible solutions that replace fossil-based materials by making the best use of residues and byproducts.
The chemical company is seeking Chinese partners to commercialize its technology named Sunliquid that converts agricultural residues such as cereal straw, into cellulosic ethanol for vehicles, a form of renewable energy that can be produced from crops such as corn and potatoes.
With the Sunliquid technology, the cellulosic ethanol yield is increased by around 50 percent compared to conventional process by efficiently converting both cellulosic and hemicellulosic components from agricultural residues into ethanol, said the company.
As the energy required for the entire process is generated from the residue instead of fossil-based sources, the technology could reduce greenhouse gas emissions by about 95 percent compared with fossil fuels, according to Clariant.

"But a strict requirement for us is that our fruit has to be safe, which means having no pesticide residues that are harmful," he said.
Biotechnology opens the path to a bio-based society in which renewable agricultural residue is converted into biochemicals and is partly a substitute for the role petrochemical industries have played since the Industrial Revolution, said Han Jianxin, a professor at the School of Economics and Management of Beijing University of Chemical Technology.
Xiao added that sites where construction residue was disposed of must be cultivated into orchards or arable land, which not only reduces the effect on the environment, but can create new agricultural businesses for local farmers.
For roses, it checks on the glossiness of the flowers, if there is any physical damage during processing and if there are any pests or pesticide residue.
While the largest contributing sources are estimated to be residues from annual crop production like wheat straw, much of the straw and stalks are presently used for cooking and heating in rural households at low efficiencies, according to BioEnergy Consult, an international consulting service provider based in Aligarh, India, in the waste-to-energy sector.

In Heilongjiang province, State Power Investment Corp has been working on a technology to compress corn straw, residues and agricultural and associated processing wastes into fuel to provide clean heating to local residents.
As the country's first domestic biomass green energy particle technology, it will make better use of the availability of large quantities of corn straw and other residues, breaking the bottleneck of inconvenient transportation and storage for biomass energy utilization, said Ma Mingjun, general manager of Shanghai Power Equipment Research Institute Co Ltd. Biomass, such as agricultural and forestry products, organic household waste as well as livestock and industrial refuse, are some of the biological materials used as fuels in producing electricity and heat.
State Power Investment Corp's attempt to compress corn straw, understory residues and agricultural and related processing wastes into fuel, however, is expected to represent a breakthrough for biomass heating in the country, said Luo Zuoxian, head of intelligence and research at the Sinopec Economics and Development Research Institute.
