Research and evaluation of the possibilities of various lignocellulosic biomass constituents to be upgraded mainly to transportation fuels. Working in various projects as a lignocellulose chemistry expert together with other researchers, engineers and business people. Planning and executing laboratory trials, mentoring and introduction of new analysis methods

Research in fractionation of biomass compounds using pressurized hotwater extraction (PHWE). aiming was to optimize yields and purity of the fractions, and evaluate the commersialisation potential of the different materials produced. Responsible of laboratory operations and reporting to corporate stakeholders.Introduction of multiple chemical biomass analysis methods, used as support in publications using microbiological data by the ecology researchers at the unitPublications at LUKEhttp://jukuri.luke.fi/discover?rpp=10&etal=0&query=spetz&scope=10024/395546&group_by=none&page=1&filtertype_0=author&filter_relational_operator_0=equals&filter_0=Spetz%2C+P.

Technical sales of mainly pulping defoamers. Technical service, performing mill-trials and product development.

TEKES funded research in improving the runnability of papermachines by enzymatically render detrimental substances derived from wood to less harmful forms. Practical laboratory trials, analysis, reporting and presentation of the results to the industry partners. Deep and profound knowledge in wood-chemistry was gained during this timeSome co-authored publications shown below.

" Isolation, and identification of emulsifiers used in paper coating latices"

Chemical analysis of pulp and process waters, by assignment of the paper industry

Chemical analysis of hemicelluloses in early- and latewood of spruce and pine
